In this issue, we introduce two new 3D printing materials: SIL 30, the inventor of CLIP, the inventor of CLIP technology in the United States, and DuraForm Flex, a 3D printing service from ARRK.
SIL 30 print samples
First, look at the SIL 30 - a silicone urethane material that has a low hardness (a Shore number of 35, comparable to the commonly used thermoplastic elastomers) and has good biocompatibility and tear resistance Designed for the manufacture of 'comfortable skin contact' products such as earphones and wristbands.
It is worth mentioning that the SIL 30 passed the biocompatibility tests of ISO 10993-5 and ISO 10993-10 and the other materials tested with it include Carbon:
Cyanate resin CE 220
Polyurethane elastomer EPU 40
Rigid polyurethane RPU 61
Rigid polyurethane RPU 70
Epoxy EPX81
Urethane acrylate UMA 90
These materials are also suitable for the manufacture of long-term wear (more than 1 month) skin contact products and short-term (24 hours) mucosal contact products, but the exception of the EPU 40, only for the former.
Let's look again at DuraForm Flex (Black), a SLS (Selective Laser Sintered) material designed for applications that require more flexibility, Shore Hardness 50-60 for use in hoses, bellows, Or flexible rubber connector.
DuraForm Flex print samples
It is worth mentioning that, with DuraForm Flex, ARRK company currently offers DuraFlorm series of SLS material has reached 5. The other four are PA, GFN, HT, and EX.
