Extrusion issue and how to print issue w/pictures

Recommended Posts

It's not over extruding. The plastic on the horns is never cooling down to freeze point so it's staying liquid. You can do the "cool head lift" feature but it will come out much better if you simply print a small tower nearby for the printer to go over there and print positioned such that the fan blows on one of the horns at the same time.

The teeth are much harder. I would do my own support in cad.

I don't think meshmixer will do the teeth - too close to other stuff.  Any cad program will import stl - For example sketchup.  Or Design Spark Mechanical.

 

Meshmixer worked well for the teeth except for one. I printed the skull at 4.5" tall so it was enlarged enough that allowed the supports to be placed along the jaw and they were easily popped off.

Thanks for all your great advise.

    • "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.
