    Default Thin wall parts to laser cut

    Hi, It's really about material choice I'm asking for advice about.

    As per the attached picture, I had this cut in the UK for £50 quid. Now as a prototype of 2pcs of 3mm cast acrylic sandwiched together to get me 6mm thickness required, I understand the low volume - high cost of parts, its all in the setup which equals time.

    The problem I have is, I would like to make maybe 40 or 50 sets of these things, for a custom bit of arty display electronics I'm woking on for myself. The cost of that would be prohibitive and given the slight warpage seen, I may not get CNC / laser cut accuracy expected due to the slight material deformation.

    Is there a material or process (not EDM ££££££) which could stay dimensionally stable while being lasered, but only have 1mm walls?

    These could be made from anything, and the dimensions of the piece are 105 x 78mm and as stated minimum but consistent wall thickness is 1mm.

    Any suggestions?

    Many thanks
    Andy

    I will try that on a piece if this tonight

    Does it need to be see through?
    That material comes in 2 or 3 layers

    Thanks, No, material transparency (or lack of) is not a concern.

    The material Delrin is used for its dimensional stability. It is a polymer material. I have seen a number of laser shops make parts from it.

    "Polyoxymethylene (POM), more commonly known as acetal or its branded name Delrin®, is an engineering plastic offering low friction, high stiffness, and excellent dimensional stability."
