TPU 90A Powder
Biocompatible SLS Powder for Flexible Parts
TPU 90A powder has an exceptional strength and flexibility to produce fully functional and durable SLS 3D printed parts in-house. Its high elongation and superior tear strength allow you to produce a myriad of functional prototypes, end-use parts and even medical devices or prosthetics that withstand the demands of daily usage. Formlabs' TPU 90A is a biocompatible 3D printing material.
Freedom of Design with TPU 90A Powder
TPU 90A Powder has a Shore hardness rating of 90A, placing it in the medium-soft material category between pencil erasers and tire treads. Nonetheless, SLS 3D printing provides design freedom that permits users to modify part designs by adding full or hollowed sections or lattices of varying density. This ability to modify the design allows for control over the durometer of the final product, allowing for the creation of harder and softer parts.

*Material properties may vary based on part design and manufacturing practices. It is the manufacturer’s responsibility to validate the suitability of the printed parts for the intended use.
FDM TPU vs. SLS TPU 3D Printing
TPU can be 3D printed on either FDM or SLS 3D printers. Each technology has unique advantages. Yet, it is important to determine what is best for your own workflow and business needs before choosing a technology.
