Default Home 3D printing

Since there has been a few mentions of 3D printing in news/technology items I figured I would through this out there for those interested.

This is the result of my own 3D printer, a Printrbot Simple I got about 12-18 months ago, that I have only just gotten around to seriously playing with.

Printed in black PLA, I 3D modeled this scale tank turret myself.

The final print is nowhere near a useable product due to my print setting selections, but even with some alignment problems I need to fix it's actually a half decent print.


Hopefully the images should be viewable.

3D model.

Thank-you for posting but why exactly is the surface so damn rough ?

Can you easily achieve a better finish with your current equipment ?

Interesting stuff. I wonder when we will get to the point where we see 3D printers in office setting (e.g., to print pens and staplers and the like). Is it a couple years away? 5 years away?

The surface finish is this rough because I am only using 0.4mm layer heights. The purpose of this print was purely to produce something I had designed.

My current printer is notionally capable of doing 0.1mm layer heights, though I would need to do some repairs to achieve that quality consistently. Being a budget printer made of wood, it has sagged a little due to moisture and neglect.

These type of printers are always going to have some degree of layering effect, though with ABS filament printers that can be removed though vapour polishing.

There are more expensive printers that are capable of greater resolution down to 0.02mm.

Don't know what the surface finish is like from an SLA printer.

I saw these photos of a model that someone online is printing:
