Xometry offers a variety of flexible materials for 3D printing.
Different printing technologies necessitate the use of various polymers or resins in order to print. Let's take a closer look at the types of print materials required by each technology, as well as their properties.

TPEs are available in a range of hardnesses ranging from 10 Shore 00 to 72 Shore D, covering all three hardness scales; however, the Shore A scale is the most commonly used.

Whenever you require a material that is resistant, flexible, and rubbery, Flexible TPU/TPE for Selective laser sintering (SLS) is the best choice. A number of advantages can be gained from this elastomeric SLS TPU, including good resilience after deformation and high Ultraviolet (UV) stability. Parts can be 3D printed for a variety of applications, ranging from the automotive to the footwear industries, by creating an interesting structural design. The material has a smooth white surface and also has good hydrolysis resistance as well as excellent shock absorption characteristics.

There are a few key properties of TPUs that are unique to them and that are beneficial to the industries.

When it comes to applications that call for high elasticity and tear resistance, EPU 40 is a great option. It is made of polyurethane and has a hardness of 40. Because of its excellent elastic behavior under cyclic tensile and compressive loads, elastomeric polyurethane CLIP Resin is a popular choice for a variety of applications. You can stretch and bend it, and it will return to its original printed shape after a few minutes.

A hardness of 35 on the scale. In addition to 3D printed parts with novel classes of polymers, CLIP technology also allows for 3D printed parts with complex chemistries such as polyurethane and cyanate ester-based resins. As a result, there is a diverse and growing selection of materials that are designed to meet common engineering needs. The SIL 30 specification sheet can be found here.

Medical supplies and equipment
All of these CLIP resins are suitable for prolonged skin contact (greater than 30 days). The same is true for short-term (less than 24 hours) mucosal contact, with the exception of EPU 40*, which is only suitable for topical application to the skin. As a result, they find their way into the printing of safe materials in the medical field as well.
