Curvy details not printing

Recommended Posts

With default settings your "walls" need to be .8mm wide as minimum. A quick workaround in your case is to set your nozzle width to .35 and your shell width to 0.7 (for two passes on the normal parts). Even though you have a .4mm nozzle it will work "okay" at .35 extrusion (12% underextruded - 12% less than normal plastic coming out and also lines are 12% closer together - all lines - infill - everything).

Always check in layer view to see how it will come out. If you can get those thin walls with .38mm then all the better. But always always make shell width an integer multiple of nozzle wicth.

0.4 to 0.35 is not 12% reduction in throughput.

Areal of 0.4 holes is 0.1256 mm2. Areal of 0.35 hole is 0.096

Reducing flow by 22% is closer to the same throughput. But I guess it is all theoretical..

(OMG I LOVE it when gr5 makes a mistake and I can catch him. My worry is the mistakes he makes which I am not able to identify, which is probably usually the case...)

Maybe try not having such fine detail if you dont know how it will look, slowly scale things down and see how much detail you can keep rather than just trying tiny things out. some things scale down well, some things need to be built with your printing in mind. I generally only print with 1.2 shell and have no real issues. if you send me your model i'll print it at 1.2 just to see how it looks.

I now kind of know my limits, and just work within those boundaries. I used to have 0.8mm shell with infill but found it was too thin, especially for my acetone dips. Now i do 1.2 with no infill.

    • "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.
