3D Printing. Rubber. Strong & Durable.

SLA Rubber Like

Our first option is a laser cured resin (SLA) Rubber Like material which is ideal for small parts where the "snip away" support structures are relatively simple.  The material features excellent surface finish (subject to the amount of support required) and fabricates your 3D printed designs in a hardness of Shore A of 80 to 85 and a high heat deflection temperature.    

Applications include prototype automotive parts for testing, plus remanufactured parts for a classic motorcycle restorations.   

• Build Volume: 145 x 145 x 175mm
• Smooth surface finish (rougher at support attachment points).
• Good Detail from 0.1mm (100um) layers with 50um option for small designs.
• Minimum reccomended feature detail or wall thickness of 1mm.
• See below for full spec.

SLS. DuraForm Flex.

Our second option for a more durable 3D printed Rubber Like material is our laser melted powder option (SLS) and the DuraForm Flex material.  This process is ideal for larger designs with complex internal structures or overhangs as the base powder material is self supporting. 

The manufacturer describes the material as 'Durable with good tear resistance, plus good surface finish and feature detail'. 

This option is slightly softer than the SLS options with a Shore A value in the 60 range and is also printed using 100um layers, The base powder material gives your designs a slightly textured finish. 

• Build Volume: 330 x 280 x 300mm.
• Lightly textured surface finish.
• Good Detail from 0.1mm (100 micron) layers.
• Minimum reccomended feature detail or wall thickness of 1.5mm.
• See below for full spec.

Additional post build finishing and sealing processes are available to make the parts watertight if required. If you let us know when you send your file(s) we'll allow for that.

Picker pads once the supports are removed. Surface roughness is somewhat worse where the supports attached but careful orientation when 3d printing ensures supports attach to the 'B' surface and does not impact on the application.
