What's Wrong With Print?

Recommended Posts

Thanks! That explains why the faster I print the more bumps (or pimples) I see! At first I thought that was when the z-stage moved down. How about the funny ridges running around the circumference? Any explanation for that? :)

Some use 250 baud to print, but I think you can do couple of things to get less pimple:

1. Slow down (replicatorG can do that during a print)

2. Close all programs except repG.

3. Use an Ultimaker controller.

The ridges is because of the "layer height". The lower the layer height, the less ribbles you see.


Some experiments of mine, from left to right: 0.05mm, 0.03mm, 0.015mm.

I was thinking that we should compile a "Ultimaker print diagnostic kit" for everyone.

So we all post our bad prints up, and the experts can critique them and provide solutions and then we compile a online manual of sorts.

Is there such a project underway? :)

    • "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.
