same here!! since those old time videos!! i do it as a job because of this dude toooo!!! its amazing to see the evolution of all these! i wish we had easy composites in BRASIL!!!
SAME!!! been following since i was in college and couldnt afford anything. now i just started to create molds and was able to produce carbon fiber parts for my motorcycle. I owe it to this man and his company. greetings from Philippines.
Agreed with all the above, I wish we had Easy Composites in Australia. It's difficult to get all the right gear, dodgy tacky tape and peal ply, trying to make do with whatever you can find! The previous bloke with Mini bonnet absolutely blew my mind 10 years ago, this information is absolutely priceless!!
I am honestly more excited for new Easy Composites videos than Hollywood movies these days. Thanks for delivering outstanding content and making the world a smarter and more capable place.
Been following since i was in college and couldnt afford anything. now i just started to create molds and was able to produce carbon fiber parts for my motorcycle. I owe it to this man and his company. greetings from Philippines. i guess learning CAD is our next goal haha
You know, as a truck driver, that had nothing to do with anything you guys do, and consequently will never be a customer, I just want to thank you for the high quality videos you put out on the process. I'm obsessed with them. It's incredibly interesting how it all works, and I appreciate you guys being so thorough. I literally watch every video you guys come out with. The dude in the video is a great presenter. Just wanted to let you guys know that your video's reach even those who aren't potential customers, and provide a great deal of entertainment.
I've become a composites expert over the past decade thanks to your incredible video. Thanks for your passion and dedication to teaching. I haven't made a single part from composite, but I know I could thanks to you.
you guys are single handly describing every step of a very complex manufacturing technique in such a comprehensible and great way one video at the time. Without you guys, formula student teams around the world wouldn't be able to make the carbon fiber parts of their cars 🤣👏
Glad it timed in well for you, yeah the design doesn't quite stop at the component, we had a look around and realised that this was a subject that had not really been covered before.
Incredible, man. I'm so glad y'alls business model allows and encourages free knowledge of how to use the product to it's fullest. These are invaluable videos. Thank you so much.
This was really good, im a journeyman tool and die maker with about 5 years of experience designing injection molds in solidworks. Fun watching those skills applied to carbon composites
The fundamental value of knowledge you are teaching in these videos is incredible ! As a start-up maker I'm following closely. As payback, I'll be sourcing materials from you. Thanks and Regards !
I used to build composite tail rotor blades for attack helicopters. This channel is always a joy to watch as the information and techniques are spot on!
Im a member of my university's baja sae team and I wish i had this video sooner. Making the molds has been a trial and error process for us and a lot of the tips in this video were things I found out after machining a ton of molds. Hopefully in the future our molds come out much better!
Thanks so much for continually producing content like this. It's unimaginably informative and helpful. Now I just wish you guys had a US-based shipping hub available!
Every single video you release is such a pleasure to watch. The work you all do is brilliant. Thank you for all the free advice and different guides and tutorials. I always leave your videos feeling inspired and with more knowledge and understanding than I arrived with. Awesome mate.
Fantastic video! I would love for the next episode in this series for you to cover CAD Techniques for ply design/creation for complex parts. Thank you for all of the hard work and amazing knowledge!
Some CAD packages will have advanced composite tools within them, or available to buy, to help with some part of the design process. The same goes with FEA tools to help you analyse the design. Similar with ply template and cutting tools.
I'm mainly a 3d printing guy with no composite making experience nor appetite to do one. Making mold is so complicated I think I need a degree just to do it. But this video proves me wrong. Thank you for the free education
This is amazing!!!! I’m looking to 3D print molds, and this will be useful. Thank you for making these videos, the quality keeps getting better and better!!!!
Thanks for the comment, yeah you get what you pay for! I was surprised that Fusion didn't have the functionality for parting lines (that I could find) most packages do.
Superb detailed runthrough, always appreciate the effort you put into making these videos. The backcatalogue of knowledge is getting quite comprehensive.
I love my luck and what the universe brings me. I have been trying to learn how to cut a body from a meshbody and I asked the 'experts' about it a few weeks ago, on numerous facebook groups. I was getting a lot of useless answers and my project got stalled because I had an uneven surface and I needed to use it as a tool to cut another body from. I have spend this last weekend also looking for the solution, without success (reading about b-rep and boolean stuff). So, out of boredom and frustration, I've decided to just watch some composite-related stuff and relax and vent my frustration. I thought I was going to lose consciousness when the video reached the 13th minute and I accidentally saw the solution to my 2-3-week search. THANK YOU!!!!!!!!!!!!!!!!!!!!!
Its our pleasure - we really get a kick out of making these videos and the help it can give so it is always great to hear they're working for people :)
Watch your video at the beginning of your channel years ago and just got back into carbon and wow same persone same amazing knowledge probs sir big giant props
Thanks for coming back to us after all this time. Yep as one of the founders/owners of the company Paul's been here from the very start. Although we like think we've improved the production quality of the videos a little since then, our dedicated studio has certainly helped.
The engine cover we will laminate in a future video, the component itself is something we’ve made for another TH-cam channel (V8Creative). The fuselage will feature next in a video about the machining of the pattern and laminating the mould. No current plans on laminating the fuselage but you never know.
Well done for presenting this topic with such clarity. I guess one thing to add would be scaling of the pattern since you are curing at an elevated temperature, unless i missed this point within the video.
It depends how precise and relevant that is for your specific application, but most CAD packages have a relatively simple scaling function should you need to do this.
Its great to see the old video's and see how far he has come in 10+ years and what is now possible to what was possible over 10 years ago. I have spoken to this guy over messages a few times and he is always so helpful. Is there a way of doing any injection moulding with carbon fibre yet or are you just making parts on the computer for plugs?
Plastic injection moulding is not a composite process at this level yet. Resin infusion and resin transfer moulding processes do exist albeit they are slightly different in both the approach and technique. There are some overlap with some composite processes, eg infusion uses vacuum in a bag to draw resin into the mould. Forged carbon fibre is a compression moulding process between 2 tools. So there is some cross over in some areas albeit there is not injection moulding in the traditional plastics sense.
Impressive. I feel like you could probably teach entire courses for people/ companies who want to go into composites. A lot of the trial and error could be avoided by attending classes with hands on experience. A lot of insanely overpriced niche parts could get so much cheaper if more people had the skills to design and produce these parts. Especially if using fiberglass instead of carbon fiber, for example.
Always a good day when there's a new Easy Composites video. One question. Is there any scaling factor that needs to be applied to the parts to fit precisely to the intended application or are the as measured dimensions accurate because there's not an issue with shrinkage when molded and laid up in this fashion?
It depends how precise and relevant that is for your specific application, but most CAD packages have a relatively simple scaling function should you need to do this.
What, no pictures of the drone flying gracefully over a local lake? Once again, this was a very helpful video. I liked the simple way of finding a split line on an uncooperative part, and the introduction of the mold clamping bushes along with best practices for using them.
Haha not in this one, but I'm going to need to make some wings for that bird in a future video, I don't think I'll resist taking it up! Glad you liked the info on the bushes, not something that's been well covered before so I hope people will find it useful.
@@easycompositestv I do think that when you talk about patterns and molds and parts, you need to motivate a bit more why (and when) we need to make molds off the patterns vs just making parts off the patterns.
Thank You so much for all of the information over the years. Is there any chance of a video for bladder molding into an aluminum split mold? I am on the hunt for bladder making materials at the moment. Thanks again!
Its something we might cover in a future video. The bladders are generally bespoke to each application with different people having different preferred materials and methods so it is hard to give an easy solution that works for all/most.
Hello. Are you planning to make a second part of this video? It would be great if you continued making the drone. Namely the wings and tail. Thanks for your work. I'm looking forward to the new videos, they're like a breath of fresh air in the world of composites.
There will be another video that features the UAV fuselage but that one will cover the machining of the pattern and the laminating of the mould sections. We do also plan to do something on wing construction so you might be in luck there!
Could you guys do a video on how you went about designing the brake lever mold you used in your 3D printed mould video? I think that would pair greatly with that video!
Hello, I really love your videos. There is a lot of useful information inside a the videos are well put together. Could you show, how the fuselage would be laminated ?
I have watched so many of your companies videos you guys made me choose motorsports over aeronautical for BEng, thankyou! Is it possible for you guys to make a video on design considerations on the final parts themselves? Like how to plan the structure for known loads and then testing with finite element analysis? I have looked around and there seems to be only a few solutions available (at huge cost lol) for composite FEA? Thanks!
Generally CAD tools with such features are only available on the higher end CAD packages or as paid add on features which makes availability not easy. You may be able to access through your uni engineering department such software.
Thanks for another perfectly well done video.. as someone working with CAD daily my brain hurt watching the flanges getting made.. with a direction of Z and am angle of 90° the flanges would be perfect and would turn around the whole part.. but apart from that, the video was good as always!
Thanks for your comment. In this case with this model and Fusion, we found this method worked best without causing any geometry issues or the tool failing to work correctly. Other models and other CAD packages may work in a more simple way.
Loving your content 😍😍 I think after multiple tutorials, I found myself in this world😅 Just out of curiosity, can you make a suspension control arms using forged carbon? Would be it applicable on the normal car? And how would you need to reinforce it? Thank you😊🥰
It would entirely be down to specific design calculations. Its unlikely to be seen on any road cars as often cost dictates the retention of traditional steel pressed parts. It may theoretically be possible on some race parts.
i love that joystick thingy you have for moving in 3d, mind sharing what that is? been doing 3d work for years as a hobbyist and yet to see such a stand alone controller!
For the parts shown, we have not added dimensionally or scaled the part for machining purposes. The parts are not super critical dimensionally so no additional tolerance is needed for the CNC machining and finishing processes being used.
Thanks for the feedback. Yes the features are pretty small so bridging wasn't really an issue due to the way it was lamainted. The laminating video will be ready soon so keep an eye out for that. It'll probably go live on the website first, so check back in the next week or so to see how we did it.
When you had the mould on the screen (34:00), you then went on to make a pattern (and then, physically, a mould from it). Can you please tell us why you didn't just CNC the model of the mould straight away, and use that to make your part?
This is a valid question which quite a few people ask. This is for a couple of reasons, firstly the longevity of a tooling board will only allow for a small number of demoulding before the tool begins to wear. For some, very low level production runs, it is possible to machine a mould directly from tooling board however, a composite mould will last much longer and allow for a higher number of mouldings to be made. The second is the CTE of the materials, Ideally the mould should be made from the same material as the parts to be made, this means that they will expand and contract at the same rates. This helps to reduce pre release of the part during curing which can occur if the mould and part and tool expand and contract at different rates during the cure cycle.
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
I'm sorry if this is not the appropriate comment section for this question. But what are the chances that you will explore basalt fiber composites in a video or as a product? I find it really fascinating that, what's basicaly a spun natural rock can have almost as high of strength as carbon fiber, and I would love to see a deep dive from you guys into that topic.
It isn't out of the question that we'll do something in the future but currently it isn't a product we carry in our range so unlikely to be a topic covered in the very near future.
Helllo ECL, really great video! I have a question, if I want the same dimensions between my orginal part on CAD and the final composite part, should I adjust the scale of the part when I create the mold? Thank you
In general no, as the pattern should be the same size as the CAD drawing, and the mould will be an exact negative of the same dimensions. For some very precise applications, scaling can be done to take into account machining tolerances, CTE during curing processes etc.
I was hoping to see what will be done to the backside of the engine cover. I'm trying to figure out a good way to add the parts that will be attatched to the top of the engine.
We aren't quite finished with the engine cover just yet so keep an eye out for the next installment. Generally speaking the mounting features can be one of the more complex challenges to overcome as the injection moulding process usually used for these components is allows for much more intricate geometry to be produced. Quite often it's a case of salvaging mounts off an original part and bonding them in place or fabricating a bracket in place of the original.
We have done this in a few of our other videos and it's a good method for ambient temperature cures, I'm sure we'll be revisiting it again in the future! Thanks for watching.
If you are planning to use CNC machining to make the pattern, I don't see why you can't just machine the mold and skip the whole process of making the pattern. You will still need to do some hand working to remove the machining marks and prepare a suitably smooth mold surface. You may even want to apply a hard surface coat. I'm just saying I think that making a pattern is obsolete now that we can use CAD and CAM.
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
On the topic of drones, the website shows that the lightest weight glass and carbon fiber sheets are ideal for RC model aircraft. Could we get a video or series demonstrating that process? If possible it’d be greatly appreciated.
Question/suggestion: Pls show how you design the actual part figuring out the fiber layers, their shape, total thickness etc. Is there a feature in Fusion which can design a laminated object calculating for layers of thickness and their shape, split the shape into shapes that can be cut on a plane surface, create cutting stencils for the plies and so?
Some CAD packages will have advanced composite tools within them, or available to buy, to help with some part of the design process. The same goes with FEA tools to help you analyse the design. Similar with ply template and cutting tools.
*Abstract* Composite mold design is a fundamental aspect of producing high-quality composite parts. This video outlines key design considerations within CAD environments for creating effective molds. It emphasizes the importance of features like trim allowance, flanges, parting lines, and strategic use of draft angles to ensure easy part release. Additionally, the integration of mold clamping elements for accurate alignment is discussed. The video covers both single-piece and multi-piece mold designs, with specific techniques for generating stock, creating mold cavities, and adding clamping features. While the provided instructions are tailored to Fusion 360, the underlying principles can be broadly applied to other engineering CAD software. Disclaimer: I used gemini ultra 1.0 (on 2024.02.24) to summarize the video transcript. This method may make mistakes in recognizing words
Hey, i would like to 3d print a multi-part mould and do a vacuum bag, wet layup. What filament would you reccomend to use for printing the mould? My first thought was to pick something that does not bond with your polyester resin (i got a bucket of that and need to use it on something haha) so i could coat the mould in polyester resin and then laminate the epoxy part onto it. This would propably be relatively easy to de-mould but the issue is that the polyester resin will deform pla prints. Have you done any research on wether, for example petg is compatible with being coated in polyester resin? Greetings from germany!
PETG is generally great for moulds and patterns as the PETG naturally releases from most resin systems meaning the main concern is mechanical grip around the layer line detail.
I've learned so much from this dude over the past 10+ years its actually crazy, and its free! unbelievable great work
Thanks for sticking with us, let's see where we're at in another 10 years!

Generally CAD tools with such features are only available on the higher end CAD packages or as paid add on features which makes availability not easy. You may be able to access through your uni engineering department such software.
@@easycompositestv thanks, I'll check!
great content thanks
helpful thanks
Like before even the video start 🙏✌️
I use freecad working on a rear diffuser hopefully everything comes out good lol
You may find the tools used work differently or have slightly different flow paths between different CAD packages.
Thanks for another perfectly well done video.. as someone working with CAD daily my brain hurt watching the flanges getting made.. with a direction of Z and am angle of 90° the flanges would be perfect and would turn around the whole part.. but apart from that, the video was good as always!
Thanks for your comment. In this case with this model and Fusion, we found this method worked best without causing any geometry issues or the tool failing to work correctly. Other models and other CAD packages may work in a more simple way.
Loving your content 😍😍 I think after multiple tutorials, I found myself in this world😅 Just out of curiosity, can you make a suspension control arms using forged carbon? Would be it applicable on the normal car? And how would you need to reinforce it? Thank you😊🥰
It would entirely be down to specific design calculations. Its unlikely to be seen on any road cars as often cost dictates the retention of traditional steel pressed parts. It may theoretically be possible on some race parts.
If you guys ever want to open a branch in Brasil, count me in.
i love that joystick thingy you have for moving in 3d, mind sharing what that is? been doing 3d work for years as a hobbyist and yet to see such a stand alone controller!
It is known as a "Space mouse" and there are a few different models.
Hey Easy Composites, awesome video! I had a quick question, regarding mold cutting - what tolerances do you typically need for a CNC machine/router?
For the parts shown, we have not added dimensionally or scaled the part for machining purposes. The parts are not super critical dimensionally so no additional tolerance is needed for the CNC machining and finishing processes being used.
Thanks for the great videos.
Did you manage to avoid bridging on the locating features/Clamping bushes (35:00) without any radius?
Br
Thanks for the feedback. Yes the features are pretty small so bridging wasn't really an issue due to the way it was lamainted. The laminating video will be ready soon so keep an eye out for that. It'll probably go live on the website first, so check back in the next week or so to see how we did it.
@@easycompositestv Thank you for the quick reply.
I will look forward to the upcoming video.
Finally I saw someone using 3D mouse... 😅
Thanks very informative !
Glad you liked it. Thanks for the comment!
When you had the mould on the screen (34:00), you then went on to make a pattern (and then, physically, a mould from it). Can you please tell us why you didn't just CNC the model of the mould straight away, and use that to make your part?
This is a valid question which quite a few people ask. This is for a couple of reasons, firstly the longevity of a tooling board will only allow for a small number of demoulding before the tool begins to wear. For some, very low level production runs, it is possible to machine a mould directly from tooling board however, a composite mould will last much longer and allow for a higher number of mouldings to be made. The second is the CTE of the materials, Ideally the mould should be made from the same material as the parts to be made, this means that they will expand and contract at the same rates. This helps to reduce pre release of the part during curing which can occur if the mould and part and tool expand and contract at different rates during the cure cycle.
very cool!
Amazing content, thank you!! if you have a branch in America I would only by from you guys
We can ship most of our products to the US with the major couriers.
Great video! Why don’t you invert the cnc mold and use that as a final mold instead of making two? 😄 thanks for all the knowledge you shared 😄
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
@@easycompositestv Great response! Thank you 🙏🏻😄
This video makes me appreciate my silent-click mouse.
I'm sorry if this is not the appropriate comment section for this question.
But what are the chances that you will explore basalt fiber composites in a video or as a product?
I find it really fascinating that, what's basicaly a spun natural rock can have almost as high of strength as carbon fiber, and I would love to see a deep dive from you guys into that topic.
It isn't out of the question that we'll do something in the future but currently it isn't a product we carry in our range so unlikely to be a topic covered in the very near future.
Helllo ECL, really great video! I have a question, if I want the same dimensions between my orginal part on CAD and the final composite part, should I adjust the scale of the part when I create the mold? Thank you
In general no, as the pattern should be the same size as the CAD drawing, and the mould will be an exact negative of the same dimensions. For some very precise applications, scaling can be done to take into account machining tolerances, CTE during curing processes etc.
I was hoping to see what will be done to the backside of the engine cover. I'm trying to figure out a good way to add the parts that will be attatched to the top of the engine.
We aren't quite finished with the engine cover just yet so keep an eye out for the next installment. Generally speaking the mounting features can be one of the more complex challenges to overcome as the injection moulding process usually used for these components is allows for much more intricate geometry to be produced. Quite often it's a case of salvaging mounts off an original part and bonding them in place or fabricating a bracket in place of the original.
Will there be a video on 3D printing moulds as well? This was a great video but a bit out of my budget...😅
We have done this in a few of our other videos and it's a good method for ambient temperature cures, I'm sure we'll be revisiting it again in the future! Thanks for watching.
If you are planning to use CNC machining to make the pattern, I don't see why you can't just machine the mold and skip the whole process of making the pattern. You will still need to do some hand working to remove the machining marks and prepare a suitably smooth mold surface. You may even want to apply a hard surface coat. I'm just saying I think that making a pattern is obsolete now that we can use CAD and CAM.
For very short production runs or proof of concept/prototyping, machining the mould from tooling board would be fine; however, for production runs and repeated heat cycling of the tools, you need much more durability than a machined model board tool could offer. You can also use the pattern to make a number of tools rather than machining multiple tools.
On the topic of drones, the website shows that the lightest weight glass and carbon fiber sheets are ideal for RC model aircraft. Could we get a video or series demonstrating that process? If possible it’d be greatly appreciated.
Sure thing, we have a few videos on drones (multi rotor and fixed wing) in the pipeline so stay tuned!
Question/suggestion: Pls show how you design the actual part figuring out the fiber layers, their shape, total thickness etc.
Is there a feature in Fusion which can design a laminated object calculating for layers of thickness and their shape, split the shape into shapes that can be cut on a plane surface, create cutting stencils for the plies and so?
Some CAD packages will have advanced composite tools within them, or available to buy, to help with some part of the design process. The same goes with FEA tools to help you analyse the design. Similar with ply template and cutting tools.
cool to know, thanks!! @@easycompositestv
Your flying wing likes like Skywalker X8 but smaller, also I found that the nose is a bit sharp than in original X8.
Yes it's very similar to the X8, about 20% smaller but being carbon the internal volume is larger. Thanks for watching!
She practical CAD technique on my mould design till I composite pattern
*Abstract*
Composite mold design is a fundamental aspect of producing high-quality composite parts. This video outlines key design considerations within CAD environments for creating effective molds. It emphasizes the importance of features like trim allowance, flanges, parting lines, and strategic use of draft angles to ensure easy part release. Additionally, the integration of mold clamping elements for accurate alignment is discussed. The video covers both single-piece and multi-piece mold designs, with specific techniques for generating stock, creating mold cavities, and adding clamping features. While the provided instructions are tailored to Fusion 360, the underlying principles can be broadly applied to other engineering CAD software.

Could you please do a video about layup in such cavity moulds?
It is something we may cover in future videos.
Hey, i would like to 3d print a multi-part mould and do a vacuum bag, wet layup. What filament would you reccomend to use for printing the mould? My first thought was to pick something that does not bond with your polyester resin (i got a bucket of that and need to use it on something haha) so i could coat the mould in polyester resin and then laminate the epoxy part onto it. This would propably be relatively easy to de-mould but the issue is that the polyester resin will deform pla prints.
Have you done any research on wether, for example petg is compatible with being coated in polyester resin?
Greetings from germany!
PETG is generally great for moulds and patterns as the PETG naturally releases from most resin systems meaning the main concern is mechanical grip around the layer line detail.
