TPU Rubber is a multi-purpose material for application using the HP Multi Jet Fusion 3D Printing system. 3D printed TPU parts produced with this material offer a balanced property profile with good flexibility, shock absorption and the possibility to print very fine structures with a high level of detail. In addition, the material is easy to print, and has good UV and hydrolysis resistance. This material is only available for 3D printing on the HP Multi Jet Fusion printer.
The gallery shown above showcases one of the early killer applications being pioneered by Forerunner 3D Printing. Using 3D Printed TPU Rubber to produce Class A safe nesting for part handling in automated equipment. One of the major pain points for machine builders has always been how to hold on to parts that are painted, chromed, or have a delicate molded in finish without scratching them during assembly. The industry standard solution has been either using machined Delrin, UHMW nesting details, or poured urethane nests in a soft durometer urethane rubber.
With the advent of class A safe 3D printed TPU Rubber machine builders have started to heavily utilize this material due to the freedoms it affords designers like:
Traditionally, rubber part manufacturing has required either the use of either an injection molding or urethane casting process to produce volumes of parts. With the introduction of this new 3d printable rubber coming onto the market a wide range of new possibilities for 3D printed rubber products is now viable. Unless a product is specifically design for production using additive manufacturing (non moldable features) typically larger volumes (5000+) of parts are made using an injection molding process and traditional (expensive) steel tooling. But additive manufacturing can be used as a bridge production method or even as the final manufacturing method for products whose volumes will never reach a level where tooling becomes economically viable.
For a much deeper dive into the low volume / bridge production potential of MJF 3D printing please check out our page on the topic. Even though the current examples are for PA-12 the information is all applicable to low volume / bridge production of TPU Rubber parts using MJF 3D printing.
TPU Rubber is especially well suited for producing lattice structures, this opens up unlimited design possibilities. Parts created from this thermoplastic polyurethane offer excellent part accuracy, a well-balanced and strong property profile as well as high flexibility and shock absorption at low cost when compared to competing technologies like SLS, CLIP, and PolyJet.
ESTANE® 3DP TPU M95A provides excellent abrasion resistance for a 3D printed elastomeric material. The high level of abrasion resistance makes M95A 3D TPU suitable for a wide variety of industrial jigs and fixtures where parts are required to endure a high number of use cycles.
ESTANE® 3DP TPU M95A provides a high level of temperature resistance for a 3D printed elastomeric material. During material testing M95A 3D TPU printed parts survived exposure for 18 hours at 200°C
ESTANE® 3DP TPU M95A provides a high level of elongation before failure. This makes M95A 3D TPU suitable for a wide array of applications that require flexibility and elasticity.
ESTANE® 3DP TPU M95A is an elastomeric material that can offer low levels of permanent deformation following prolonged periods of compression depending on 3D part design and geometry.
