Re: 3D Printers

Google Sketchup is a bit more precise...

But YES for real world precision a true cad program like Autocad would be preferred over a 3D modeling app like 3DMax, Lightwave3D, Blender, Hexagon3D, etc...

I can see why the author used Blender. His printer is open hardware and he wants to reach as large an audience as possible. People can download Blender for free, and is cross platform (Windows, Mac, Linux). Most people grabbing those files are converting it to a format for printing (like STL), not editing; for those who do want to edit there's nothing stopping you from importing it into Autocad.

Personally I find Blender's interface confusing. But it does export to a variety of formats and it hasn't let me down.

Google Sketchup is terrible for 3D Printing. Its not a solid modeller, its a surface modeller. There are plugins for exporting to STL but they only work about half the time (you can also import to Meshlab and export, but that doesn't always work either). Its actually a bit disappointing as I found Sketchup really easy to use. If more slicers could use Sketchup formats natively or if they came up with a clean way to make a solid model and export to STL, I'd definitely use it myself.

For the real world it really does depend on your application. Autocad would be great if you needed an extremely precise part, but it would be laughable to use it for jewellery or dental applications. Some modellers have 3d printing specific features which make them more appealing for this, like Rhino3d.

I've heard of it but never tried it. I did purchase a copy of TurboCAD years ago but it confused me... LOL

Wings does look like it would be pretty useful. I will check it out.
