Material description

Durable Fine plastic objects are printed from a UV curable resin. Two proprietary resins are mixed and printed simultaneously to create a unique digital material that has properties comparable to ABS. The color is a pale green and becomes slightly translucent when the wall thickness is thin.

Durable Fine plastic has a high impact resistance of 65-80J/m (1.22-1.5 ft lb/inch) and a heat deflection temperature (HDT) of 58-68°C

Orders using this material generally ship in 2 weeks. Find out more.

Technology description

Durable Fine plastic parts are made on a Objet Connex 3D printing machine. These machines work similarly to inkjet printers, but instead of using ink they use resin. The resin is printed onto a surface and then cured by a passing UV light. A jelly-like support material is printed alongside the resin and is removed using a high pressure water spray in post production.

Design tips

GEOMETRY:
The minimum recommended wall thickness for Durable Fine plastic is 1mm and minimum detail size is 0.2mm. However, objects need enough strength to be self-supporting. For example, large, bulky geometries connected with thin structures (like a character with a big head on a skinny neck) could break in handling (especially in shipping) and should be designed to avoid this. If you have features that extend and converge to a point (eg a cone) they should be at an angle greater than 10 degrees.

Nested objects (objects floating within another object), hinged objects, and interlinking objects like chains work well using this material. A gap of 0.5mm between objects should be used for them to separate correctly after printing.

Sprued designs are not allowed in this material.

SUPPORT MATERIAL:
A jelly-like support material is printed alongside the plastic and is washed away using a high pressure water spray in post production. Your model needs to have enough strength to survive this process. If you have very intricate geometry that the water spray cannot get into, then the support material may not be able to be cleaned off.

Hollow objects require a drainage hole to remove the support material. For example, a hollow cube needs a small opening somewhere in it so that the wax support material can drain out after printing.

FINISH:
The surfaces of parts are smooth and have a matte finish where the support material encases the geometry. However, where the support material doesn't need to touch the part, ie the top surface of the part, the finish will be glossy.

NB: The printer determines the orientation of your model to get the best results so this won't be something that can be specified. Generally parts will be arranged so that the z height is the smallest dimension.

Yes it can. It is acrylic based photopolymer so should be able to be painted in the same way as acrylic.

Thanks, but that doesn't help me much. What type of "thermal post treatment procedure" is used, if any?

I want to bake a finish onto parts made from this material, and need to know what temperature it can be taken to before it starts to deform.

Is this material food safe (i.e. can someone use this to make spoon for everyday use)? Or which materials are food safe that you have?

This material is not food safe. Only glazed ceramic is food safe.
