3d % Scaling For Wsf

Discussion in 'General Discussion' started by 1302094_deleted, May 22, 2017.

  1. Using 123D to scale up a part (80,20,5 mm), then subtracting the scaled up part from another larger part. The purpose is to fit the (80,20,5 mm) printed (WSF) part into a larger part snug enough that little pressure required to install, yet still snug. Cleaning loose debris will be required. What percent scaling up for Shapeway's printing do people use? For example 100.03 %. Also percent scaling for fitting acrylic into WSF? Thank you.

    If I'm understanding this correctly you want 2 parts to fit with each other?
    You want to do this by making space based on a scaled up of the par to fit inside?
    % scaling isn't the way, it depends on the dimensions.

    It's a surer way if you extrude the inside geometry by a specific number.

    I'm not that familiar with WSF, a spacing of around 0.5mm is good for fitting things, this gives a 1mm overall play between the two objects.
    WSF will not be that precise and there will be variation in the print.
     
  3. Thank you. Will try .5 mm.
