Not many printer can print silicone, but do remember that silicone is very hard to post proces, and any structure in the print will not be able to smooth out.
if you are looking just for cheapest test parts, and don’t care for the structure, then this is the ways to go.
otherwise you will get better results to have the object printed, and have molds made to cast in silicone, or polyurethane rubber.
it is more time consuming and costly.
but you could also look for printers that can print flexible PLA, I have seen some good prints with this material.
and when you want a lot of prototypes, or limited range of won devoloped / designed object, you could even consider investing your own 3D printer
I’ve looked at this method and it looks to be quite sketchy and rough even when casting has been fairly sucessful. Direct silicone printing looks like it gives much better results.
See the images i made for a customer. It is a flexible damper for a insertbearingblock and it looks Ok . It won’t be as smooth as the watch you sell because of the somewhat lower resolution. but i will do for prototypes
Hello @picsma. Very impressive. Is it the kind of technology that’s likely to result in a moderately priced desktop printer or is it inherently bulky and/or cost prohibitive for smaller sized printers?
Dear Gavbrum, have you considered FilaFlex filament? This is similar to NinjaFlex and has similar properties to silicone in that it is tough and flexible. We have stocks of the filament and by late next week we will have a printer specifically designed to print it. When we ordered our flexible filament stock, they sent us a watch printed in the material, so I can even send you a photo of it.
Yes. It has a certificate for use in medical situations, visit the Recreus web site to download it. The material seems really tough and the bond between layers is strong, so I would expect it to be good for these applications. The problem with the material is that it is difficult to print using a standard print head, that is why we have invested in a custom made machine designed to use it.
@picsima: Hi, I too require a part to be printed in silicone. Checked out your website and was wondering what is the maximum surface finish you can achieve because as far as I have heard 3D printing silicone might not have a very smooth surface finish.
Because we are very well versed in silicones, we DO have silicone material that we HAVE 3D printed. We can do prototypes, or 100s of units. Let me know if you are interested in having us do your product.
