All of the software parts are the most difficult for me to understand, from building the models to the slicing and using some of the scanning tools. I have a hard time understanding why there isn't more integration from model to print.

I currently don't have a 3d printer. Guess the most difficult would be to learn how to design the object(s) that I need/want to create

[Rixsaun]

i dont have any formal training in autocad or any design software. Its been a little bit of a struggle in which i have been trying to self teach the software

[3dds]

I am self studying the software I am using, I usually have no idea if the file - thickness, dimensions details - are ok to print before I upload it to one of the service companies. I wish it could be a easy checking software or plug in for printer/material I wish to use.

What programs to use. I am having trouble deciding whether to invest in a program such as solidworks (free while im in school) or start to learn one of the free programs.

Where to start if I want to connect with local makerspaces, enthisiasts, hobbyists outside of professional design settings

[badscr]

Calibrating, I still don't know if I have the first layer correct or if I'm over extruding, all I know is that am happy with the results of the print, still haven't printed anything pas 3 hours,

Oh and part worpping.

I've got a printrbot simple.

The modeling in 3d to make an object for printing. But, that's just a matter of inexperience. I'll learn.

The workflow from model to printer. "printer" suggests a simplicity of command+P and click OK. 3d printing you have to have the right format, slice it, send it the printing software which translates to g-code, ... and this is probably an over-simplification

3d modeling is the biggest hurdle. Without the knowledge to 3d model, most people are stuck with what CAD files they can find on the internet
