What your process engineer actually checks

Rubber-like flexibility you can print

At 88–90 Shore A with up to 400% elongation at break, GF TPU 23 prints soft, bendable parts that stretch and compress like moulded rubber where rigid nylon powders would crack. It is the grade to reach for on seals, grips, cushioning, living hinges, and impact-absorbing lattices.

About this product

Kings3D GF TPU 23 (KSTPU23) is a flexible, rubber-like TPU powder for SLS 3D printing — a thermoplastic polyurethane elastomer that prints tough, bendable parts at 88–90 Shore A with up to 400% elongation at break. The powder is white and finished parts come out in a natural colour. It runs on Kings and other open, TPU-capable SLS systems, and we supply it from US stock with starting parameters to run it.

Why engineers choose GF TPU 23

A rubber-like SLS elastomer for parts that need to flex, stretch, and absorb impact.

Rubber-like at 88–90 Shore A

A soft, flexible durometer that bends and compresses like moulded rubber — the reason to pick GF TPU 23 over rigid nylon powders for elastomeric parts.

Up to 400% elongation

High elongation at break (DIN 53504) lets parts stretch, snap-fit, and deform repeatedly without cracking — ideal for living hinges, seals, and grips.

Impact and abrasion resistant

The TPU elastomer chemistry absorbs shock and shrugs off wear, so parts survive drops, cyclic loading, and contact friction where brittle materials fail.

Runs on open SLS platforms

A powder-bed TPU with a 160 °C melting point (ISO 11357) — compatible with Kings SLS (P440 line) and other open, TPU-capable SLS systems, tuned per machine.

How we supply it

A production print center supplying proven powders — not a warehouse reselling boxes.

Step 01

Proven, then stocked

We run a production SLS print center in-house. We only stock powders we have printed and validated ourselves — so what ships is a known quantity, not a catalog listing.

Step 02

Stocked in California

GF TPU 23 ships from our Los Angeles warehouse in 1–2 business days, sealed with a batch data sheet, plus starting build parameters for common SLS platforms.

Step 03

Custom formulation on request

Need a different hardness, colour, or refresh behaviour? Tell us the target and we will discuss a custom SLS elastomer option with our material partners.

Common questions

How flexible is GF TPU 23?

GF TPU 23 (KSTPU23) prints rubber-like parts at 88–90 Shore A hardness (ISO 868), a soft elastomer durometer comparable to moulded TPU rubber. Combined with up to 400% elongation at break (DIN 53504), parts bend, stretch, compress, and snap-fit repeatedly without cracking. That makes GF TPU 23 the grade to choose over rigid nylon powders when you need living hinges, seals, grips, cushioning, or any part that must flex in service. Exact flexibility on your part depends on wall thickness and geometry.

Which 3D printers is GF TPU 23 compatible with?

GF TPU 23 is a powder-bed SLS TPU with a 160 °C melting point (ISO 11357), compatible with Kings SLS systems (P440 line) and other open, TPU-capable SLS platforms. Because it is an elastomer powder, it needs a machine that can handle flexible-material processing and per-part refresh; build parameters are tuned per machine. Tell us which SLS system you run and our materials engineer will share starting parameters so you can print GF TPU 23 without a long calibration cycle.

What is GF TPU 23 made of?

GF TPU 23 (KSTPU23) is a thermoplastic polyurethane (TPU), a member of the thermoplastic elastomer (TPE) family. In powder form it is white, and finished SLS parts come out in a natural colour that can be dyed. The TPU chemistry is what gives the material its rubber-like flexibility, high elongation, and impact and abrasion resistance. It is a single-component elastomer powder — not a filled or reinforced nylon — so parts stay soft and compliant rather than rigid.

How strong and durable are parts printed in GF TPU 23?

Parts printed in GF TPU 23 reach 20 MPa tensile strength with up to 400% elongation at break (DIN 53504), so they stretch far before failing. The TPU elastomer absorbs impact and resists abrasion, meaning parts survive drops, cyclic flexing, and contact wear that would crack brittle materials. It is a flexible, energy-absorbing material rather than a stiff structural one — best matched to seals, cushioning, grips, and shock-damping lattices rather than load-bearing rigid brackets.

What colour are GF TPU 23 parts?

GF TPU 23 powder is white, and printed SLS parts come out in a natural (off-white) colour. Because the base is a light natural tone, parts can be dyed to a range of colours in post-processing if your application needs them. For consistent appearance across a batch, we supply the powder with a batch data sheet so colour and behaviour stay repeatable. Tell us your finishing requirement and our engineer will advise on dyeing GF TPU 23 parts.

How should I store GF TPU 23 powder?

Store GF TPU 23 (KSTPU23) in its sealed pack in a cool, dry place away from direct heat and moisture, and reseal any opened container promptly. Like most SLS polymer powders, TPU can pick up moisture from humid air, which affects flow and part quality, so keep it dry and let it reach room temperature before opening a cold pack. We ship it sealed with a batch data sheet. Vendor shelf-life and refresh figures are not published — request the batch data sheet for your build.

Can I order a sample before buying a full 20 kg pack?

Yes. Rather than a free-powder giveaway, we offer a paid benchmark print in GF TPU 23: send your STL and we print a representative flexible part you can bend, stretch, and fit-check in your own process. It is the fastest way to confirm GF TPU 23 suits your application before committing to a full 20 kg pack. Use the Talk to materials engineer button to arrange it.
