- In this video, we design some hardware handles for mass production 3D printing and discuss crucial considerations to ensure optimal functionality and strength. Traditional handles, historically crafted from metal or wood, have evolved with the advent of mass production 3D printing. By embracing the capabilities of this technology, we unlock endless design possibilities and the ability to reinforce parts with additional material. Join us as we demonstrate the process of creating handles that are both aesthetically pleasing and structurally robust

About Slant 3D
🏭 High-Volume 3D Printing: Scalability Meets Flexibility
Slant 3D's Large-Scale 3D Print Farms utilize 1000's of FDM 3D printers working 24/7 to offer limitless scalability and unparalleled flexibility. Whether it's 100 or 100,000 parts, our system can handle it reliably, while still allowing for real-time design updates, ensuring products evolve with the times. This adaptability is key in today's fast-paced world.
🌿 Sustainable Manufacturing: Eco-Friendly Efficiency
Embrace a system that drastically reduces carbon emissions by eliminating carbon-intensive steps in the supply chain, such as global shipping and warehousing. Our approach minimizes this footprint, offering a more sustainable manufacturing option.
⚙️ Digital Warehouses: Parts On-Demand
Think of print farms as a "Digital Warehouse", meaning we can store your parts digitally on a server rather than physically on a shelf. parts are available on-demand, reducing the need for extensive physical inventory.

I'm a Blender modeler. I don't use CAD software. But I am amazed every time I see a video of symmetrical modeling without the use of a mirror. Doing each step twice is very inconvenient.
You can mirror in the software they are using they just.. chose not to.
I've just started using blender and it feels like when I started Photoshop, but with the complexity squared. Super powerful software, but might type a CAD software too as I'm only using it for 3D prints.
I use fusion360 and it’s a no brainer that only 1/4 of this should have been done.
@@VV-om8vv I'll try it out, thanks for the recommendation 😊👍 Ive been using the software that comes with the flash forge to splice and bodge things together because I'm just making toy gun parts for my sons. But I do want to get into more functional exact stuff so this might help 👍
Great video! On the subject of texturing the part since it is low cost.
One application that immediately came to mind was making the texture provide additional value - use the pattern to embed braille for sight-impared users, or simply to give a tactile indication of what you've grabbed in a dark room for example
That is certainly an option
Very underrated channel! These construction infos are pure gold. Thank you so much for sharing your expertise!
Glad you like them!
I printed something which used a functional screwhole and it had the surprising property that with PLA a screw which fits but whose threads do not will naturally make the threading as it screws in and stay extremely well. Notable quirks include that that the screw hole must be sized perfectly and you specifically don't want to get it very tight or use a washer because that will just destroy the plastic without holding it in place any better.
This is much better than the prior cup example, more practical and a likely real-world usage scenario. 👍 It's interesting needing to balance print orientations between keeping the screw from splitting layers, or on its side for maximum pull strength.. I almost wonder if tipped ~45 degrees would give a good median between sideways and standing up. But if torquing the screw still splits layers there's no point. Just haven't seen 45 degree printed screw holes ever tested prior.
Another good video. Some thoughts:
1. As the grip on the inside just needs to be perpendicular to the top of the handle to counteract the forces from someone gripping it, a simple wavey pattern parallel to the handle will not only provide sufficient grip, but will also be a *LOT* faster to print than a lot of little cylinders, as the extruder can just fly from end to end without stopping, with the waves formed from layer offsets.
2. Most handles are designed to be fastened from the back, so incorporating a hole that includes a larger opening for inserts and threaded the full length for the most popular screw sizes will ensure that the front is completely smooth and it is still well-secured.
3. Even faster and cheaper to print would be designs that are intended to be used with standard metal tubing/dowels/etc. End-users could then choose for themselves how long the handle will be. (There would need to be a way to firmly anchor the grip to the standoff, obviously.)
Cheers!
Great example where a new manufacturing method enables better design!
Great video! As it happens for the last couple of weeks I have been struggling to design a handle for a tool box.
You mention that layer lines are aligned for strength but this would require printing the handle standing on it's side -- and not sure how you would do that without significant support for the side of the handle that extends. I'm pretty sure that if you printed this in the lengthwise direction that you would not have enough strength to hang from due to layer lines.
Really love these design videos. Even for me, Joe Hobbyist, they make sense. Thanks a million.
Thanks for watching
Shall I ask about which printing orientation did you use for this handle? Tank you
Saw a post on reddit a while ago about printing handles that can carry your bodyweight. But even the moderators felt the need to intervene the comment section and said that "it's not safe do on a 3d printer". Just a bunch of kids with untuned, 3d printers.
Design is everything.
in my defense, tuning things right is hard
Looked like a VW van handle in your right hand in beginning of the video!
Liking these videos much better than the ones complaining about other manufacturing processes. Sometimes 3d printing isn't the best option but some of your other videos seem like you get mad about it. Just my opinion.. I'm still here so you're doing good haha
Great example of how durable PLA can be. I have a dust pan I printed in September of last year and it is still going strong, when even the metal ones would break after 6 months or less.
Design is more important than material.
I never thought that Pablo Schreiber would one day give me advice on 3D-printed door handles.
Are chamfers better than Fillets? Structurally?
Yes
No, filets are stronger. Any sharpncorner creates stress risers, and parts ultimately fail at those points. In 3d printing, filets are much more difficult to create properly, so chamfers are preferred and within Abe 3d printing bubble are more effective.
You are really really really really really really Amazing🎉
Really? lol
Yes yes yes yes
You work really hard to guide us you are really really really amazing❤❤❤🎉🎉🎉
Thanks
