ONE MORE VIDEO TO FUEL MY FUTURE PROJECTS...I get so much great info from watching these things...and it's all helped me to achieve some pretty serious items...I now have a silicone tarantula mold that I reproduce resin tarantulas from, as well as having made silicone molds of Ballet Flats for a client to make resin Ballet Flats for her customers...SO DANG COOL...I APPRECIATE YOUR WORK 🔥🔥🔥
Clean work! Thanks for dropping in the cost of a project like this. Insightful. Keep up the great work Eric!
Thanks
We like that stand you made for dealing with the bottom fill and tubing management. That can be a tricky configuration to hold and fill everything and not make a mess. Another good tutorial, Eric!
Thanks! And thanks for your continued support and excellent products
Appreciate the content as always! Bravo- would love to see the process of reverse engineering what urethane or moldable plastic to choose from "old" or obsolete parts... As always- be safe- and at peace!
Very cool! I am only subscribed to a few channels and this is why I am to yours. There is a difference between a pro and wanted be. I stared to molding when I was 7 years old with friends, from oil cans we created a furnace that we melt all kind o of plastics that melts into the sand mold in the ground, we created difference products and parts that where better than the original.
Am I glad I found your channel! Am I am much less skilled tinkerer, but this stuff is exactly my speed :)
I see the young man in you, Eric, who's curious about things and experimenting with stuff. This early Millennial recognizes you. Thanks for sharing! :]
What a beautiful thing to say! As his daughter, I agree ❤
Nicely done Eric! Having the 3D model beforehand is blessing, speeds up the process tremendously. I'm battling with a project where I have to fit panel inside fairly complicated blowmolded case and the hours just fly.
Very, very interesting and informative video. Loved how it turned out. Thank you.
Really Enjoy These. Like the process your using, including 3d and resin real good use scenarios Thanks for posting
Informative and entertaining as always. You frequently show methods I'd never have thought of in my hobby molding projects. The animation of text sliding up from the bottom of the screen is different! It used to have a little "hitch" in it that would make me stop breathing until it recovered and hit its mark.
Always making adjustments
Nice video. Great job.❤
Thanks
Out of curiosity, when you say that it costs around $1000, is that your cost or your cost plus time spent (as in what you charge your customers)?
Very interesting seeing that resin part to be used with platinum silicone right out of the printing process - is there any process that you follow to minimize silicone cure inhibition while using resin print?
Shellac works very well
I think you need a small injection moulder tbh.
I've loved your videos for years now, thanks for adding in cost. How did you get into doing this line of work?
This part of what Industrial Designers do.
Another excelling piece of art. Congrats.
I am in the process of creating a hard mold either from epoxy or urethane resin that will be used to create small silicone parts. The silicone parts will have many small holes (1mm diameter) in it and I am wondering if the 1mm diameter molded pillars in epoxy or urethane will be strong enough to not break while demolding the silicone parts. What hardness do you recommend for such a mold?
I would not use anything above a shore 40
@@EricStrebel Thanks. Also, can i mix PTFE nanopowder in urethane as a permanent easy release? I cant use standard mold release coatings like vaseline or other additives due to the application sensitivity.
Hmmmm, not sure, test it out and see how it works. Let me know.
Thanks for sharing! Great project. If you weren't filming, besides the tin cure, would you have solid sides for the mold support to help limit the flash?
Maybe just additional key lock on the edges
@@EricStrebel I guess you could throw that into the 3d printed midplate. Easy!
Correct
Is the syringe a consumable of the process or can you clean that up to reuse?
Reusable 😀
@@EricStrebel I can't work out if you are laughing at the absurdity of the idea that it would be reusable or if it just plainly is reusable. I'll look it up!
It's very reusable
No joke, you blow some compressed air in the nozzle side of the syringe and it pops right out. And sometimes across the room too!
Yup
Would love to see over moulding in small batches
Does pcbway do polyurethane as well? If not do you know of a company that does polyurethane molding or printing?
For such a small mold would it be possible to pour the silicone and then place the whole mold into the degassing chamber? Or are their other reasons that wouldn't be a good idea?
I tried that once on a project I was working on. Half of the silicone ended up in the bottom of my vacuum chamber. Had to redo the mold. It was a mess. Lesson learned.
Молодцом!
💪👍
AWSOME work 👏 👌
What is this vibration sensor for?
Secret
Is that a challenge coin......
When you say a project like this runs about $1000 are you talking about how much you charge, or how much the materials cost you to make this parts?
What I charge
@@EricStrebel got it, thanks again!
Have you considered hot glue instead of PVA? Hot glue is ridiculously easy to remove with a spritz of alcohol.
not an option, to thick and not easy to control.
So cool. This is a really great process.
I have to say though, $500 OFF a Formlabs, when you can get printers that produce far better surface quality for LESS than $500… 🤔
Not likely
WOW! That top part looked awful out of the printer. You should not have to do so much rework if your printer settings are good, you should get a nearly smooth part right out of the printer. This looked horrible!
Yes, the heater is broken on my form 2, failed print parts in the resin, causes print issues
Right? It looked like a bad FDM print not resin. If Form is giving him discount codes to pass out they should send him a fully dialed in printer.
The form 2 is an older machine, the form3+ is the new machine.
It cost you $1000 to do this? I think there are several other techniques you could have chosen for less.
I think he charged 1k for the job.
damn 1k is a ripoff lol
Absolutely, you're right. , I should change more.
Great delivery and insights!
(2:38) Man, you have the worst luck with 3d printing. Those parts look....how do I say this nicely...well, I guess I won't say anything. But it's bad man. That's really bad.
Eh, some bits in the resin from a failed print, not an issue for that part.
@@EricStrebel I was speaking to the over all quality. Is your form 2 heated?
The heater has failed in the form 2....it's an issue I have to deal with.
