1. What is TPU 90A powder?

TPU 90A powder is a thermoplastic polyurethane (TPU) material designed specifically for Selective Laser Sintering (SLS) 3D printing. With a Shore hardness of approximately 90A, it offers an excellent balance of flexibility, elasticity, and mechanical strength, making it suitable for functional and end-use parts.

---

2. What does “90A” mean in TPU 90A?

The 90A refers to the Shore A hardness scale, which measures material softness. TPU 90A is:

• Flexible but not rubber-soft

• Durable under repeated bending

• Strong enough for load-bearing flexible components

It sits between very soft elastomers and rigid plastics.

---

3. What are the main advantages of TPU 90A powder for SLS?

Key benefits include:

• High elongation at break (>350%)

• Excellent tear and abrasion resistance

• Good elastic recovery after deformation

• Stable SLS processing behavior

• Smooth surface finish

• Suitable for functional, production-ready parts

---

4. What applications are best suited for TPU 90A SLS powder?

TPU 90A powder is ideal for:

• Seals, gaskets, and O-rings

• Flexible housings and protective covers

• Shock-absorbing components

• Wearables and footwear parts

• Automotive flexible components

• Ducts, tubes, and bellows
