Walls are too big

Recommended Posts

Hello,

if I print a cylinder with a hole in it, the hole will be a little too small.

Cylinder is d=30.5mm. And the printed cylinder will have 30.1mm

A hole of 7mm in it and a layer size of 0.2 the Hole will only have 6.5mm

A 26.4mm Hole will have 25.9mm

Material is PLV. Skin enabled.

The Material amount is good.

It looks like, that walls are general too big. Is there a setting or trick to skale the model to fit better (not in Z)?

Thanks

The difference in model hole size and actual hole size is mostly due to shrinkage of the material. This shrinkage depends on the size of the hole and the things printed around it. So a general scale factor is not the best solution, the best solution is to modify your model and adjust the parts there. Because other features in your model will shrink differently.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
