How to Make Silicone Parts: Silicone 3D Printing, Silicone-Like Materials, and Silicone Casting

[@Formlabs]

Are you looking to produce silicone parts quickly for prototyping or short runs? It’s never been easier, thanks to 3D printing! Read more: bit.ly/429yJQj #sla3dprinting #formlabsresin #stereolithography #silicone40A #silicone3Dprinting

The irony of talking about how these materials and manufacturing process can take your lead time form 2-3 weeks to 8 hours. Yet to buy the materials the lead time is currently 8 weeks from you guys. LOL...

[@TheSunChaserUS]

Thats to start, if you have a production/bizz then its just ordering at the right timing

[@damian-offthegrid4092]

It’s currently 12 weeks fyi… 😒

[@seekertosecrets]

This presentation is very impressive.

[@rescuemethod]

What about labor costs? This is why companies use automated injection molding. Tooling costs are high up front but then material and labor costs are much much lower compared to resin so the overall price is lower. If Formlabs could automate the process affordably and sell Resin for a price in line with production parts then I might be a customer.

[@bhengineering]

This is for low volume fab. Automated injection molding isn't worth the upfront cost for most prototypes or short production runs. It's why people do silicon casting now, which is far more labor intensive than just printing the finished part and post processing it.

[@rescuemethod]

@bhengineering yes, very short production runs... I'd like to use resin printing for short production runs of 100-400 parts but still hard to justify due to resin and labor costs.

[@automan1223]

will 40A silicone resist high voltages found in automotive ignition systems ? Did I see that ?

[@ovalwingnut]

I feel like I'm not getting the whole story.. just saying.

[@ilwhana]

I thought that I have to use support material always for each printing. 😮

[@yveslegrand9826]

Unfortunately silicone like materials is NOT real silicone....

[@bhengineering]

Then print with the 40a silicone instead of the alternative budget friendly option #2. They are just sharing both options as people don't always need to spend the extra $ for silicon when all they need is 'soft' parts. Silicon printed parts are for applications that need soft + high temp + high chem resistance + black, or any combination of those.

[@ovalwingnut]

Yes. Lots of red flags.. it's what they are "not saying" me thinks.

[@ericlajoie8028]

Bad dragons for allllllll!!!!!

[@jkl970]

i would assume this isnt PLATINUM CURE silicone. might be tin cure. i wouldnt do it this way. if you wanted to use a resin printer to make that, you can print it in hard resin, then cast it in silicone. repeat silicone molds using a pressure pot.

[@noway8233]

Very cool but the Devil is on the details , as always😊

[@ovalwingnut]

Yes. My spidy senses are tingling...

[@timhofstetter5654]

Your writer has obviously never used a 3D printer.

[@MUNDHIRALKIYUMI]

Your material price are very high!

[@KyleFalconer1]

When they're the only ones supplying that kind of solution, they can charge whatever they want. 🤷‍♂

[@NUeB_RCFPV]

​@@KyleFalconer1 Other companies offer Shore A-43 resin at about half the price e. g. - they just don't advertise it as silicone, because it isn't.

[@Liberty4Ever]

I have a product that would be much improved with 3D printed 40A silicone, but only at a cost of 10 cents per gram or less.

[@daleolson3506]

I wouldn’t use dorman as a benchmark. Kill th music

[@karlosss1868]

Yerrrr.... a lead time of 8 weeks and no viewable pricing lol.

[@Cryous]

They listed it awhile ago at $350 or $450 a liter I can’t remember.

[@johnlocke3481]

Dorman Automotive is a terrible company.
