01 / Why choose this material
Properties and uses
of TPA 90A.
Polyamide elastomer for Multi Jet Fusion, suitable for flexible parts that recover their shape. Geometry and thickness influence perceived flexibility.
TPA is a polyamide elastomer for 3D printing. The 90A designation expresses a nominal Shore A hardness. The flexibility you perceive in a part also depends on its thickness, shape, and structure, so it is advisable to validate the functional geometry.

TPA 90A applications
Gripper tips
Gripper tips adapted to contact with an object.
Footwear prototypes
Footwear prototypes to validate geometry and flexion.
Flexible protectors
Flexible protectors for housings and mechanical assemblies.
02 / A choice based on usage
Choose TPA 90A
based on your part.
These criteria help define the material, geometry, and working conditions before manufacturing.
01
Part flexibility
Walls, ribs, and thickness affect how the component deforms, even with the same material hardness.
02
Elastic recovery
Define the stroke, load, and movement repetition for protectors, grips, and dampers.
03
Casting alternative
For runs with texture and product appearance, compare TPA printed with flexible PU in a silicone mold.
The part's function is the starting point.
Indicate loads, temperature, environment, and appearance needed. If the drawing requires a specific grade, include it in the request.
03 / Finishing also counts
Finishes and appearance
of TPA 90A.
Material and process define the surface. These are the key factors for specifying your part's appearance.
Printing finish
Matte and slightly granular surface typical of the process. Orientation and geometry influence the result.
Shape and detail
Define thicknesses and areas that must deform or fit. The reference part shows the material, not the behavior of any design.

Include the expected appearance and usage conditions in your request to confirm the quote.
04 / From design to quote
MJF 3D printing
of TPA 90A.
Multi Jet Fusion printing builds the TPA 90A part layer by layer on a powder bed. Afterward, it cools, the powder is removed, and the planned post-processing is performed. The design must allow cleaning internal cavities.
Upload a 3D model per part, for example in STEP or STL. SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, and 3DM files are also accepted. Add a PDF drawing with functional dimensions and assembly requirements.
Upload your file and request a quotePart tolerances
Printing tolerances depend on geometry, orientation, and material. Indicate assembly dimensions on a drawing for the team to confirm feasibility. CNC machining tolerances are not automatically applied.
Quantity and cost per part
The price per part usually varies little with quantity. Producing more units does not imply the volume savings achievable with machining or molds.
Quote in 24 hours

How much it costs to manufacture
The price of your part
in TPA 90A.
The price of printing TPA 90A depends on material volume, geometry, manufacturing layout, and post-processing. Quantity usually reduces the unit cost slightly.

Frequently asked questions
Before manufacturing
in TPA 90A.
Properties, applications, and manufacturing: answers to prepare your request.
What is TPA 90A and what properties does it have?
Polyamide elastomer for Multi Jet Fusion, appropriate for flexible parts that recover their shape. Geometry and thickness influence perceived flexibility. The 90A designation indicates nominal Shore A hardness, not tensile strength. Final values depend on the powder and printing parameters.
What parts can be manufactured in TPA 90A?
You can manufacture damping elements, clamp grips, shoe prototypes, and flexible protectors. Multi Jet Fusion printing allows validating complex shapes without manufacturing a mold. Define loads, environment, and finish so we can review the application.
What does 90A mean in a 3D printed TPA part?
90A indicates the nominal Shore A hardness of the material. It is not a tensile strength value. Thickness and geometry greatly influence how much the finished part flexes, along with the powder and printing parameters.
TPA 3D printed or flexible PU for a protector?
TPA allows printing the geometry without manufacturing a mold. Flexible PU casting can replicate product color and texture in a short run. Compare quantity, hardness, appearance, and deformation before choosing the process.
Is TPA transparent printable in this catalog?
No. The 3D printing TPA in the catalog is opaque. If you need to combine flexibility and transparency, you can consider transparent flexible PU obtained via vacuum casting, checking the polyurethane resin, the thickness, and the finish.
How much does it cost to 3D print a TPA 90A part?
The cost of printing TPA 90A depends on material volume, geometry, manufacturing layout, and post-processing. Quantity usually reduces the unit cost slightly. Upload the 3D file to the Proto&Go! platform to receive a quote with cost and lead time.
What tolerances can I request for a TPA 90A part?
Printing tolerances depend on geometry, orientation, and material. Indicate assembly dimensions on a drawing for the team to confirm feasibility. CNC machining tolerances are not automatically applied.
What file do I need to manufacture a TPA 90A part?
Upload a 3D model per part, for example in STEP or STL. SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, and 3DM files are also accepted. Add a PDF drawing with functional dimensions and assembly requirements.
