Modern Lego Art (torture test) by danielkschneider Dec 22, 2012

Description

Printing torture tests takes time. Therefore the best models must have an extra purpose. This one has been repurposed into a modern art scultpure that can decorate Lego worlds...

The sculpture is a bit smaller than the original (64/65) since I wanted it to fit on a 8x8 Lego brick. Also added the artist's name ;)

Even though I love it, this kind of defeats the torture test in that one important piece is to see how well the machine can print the single flat strip without support underneath.

Instructions

Slicer settings

I printed this with 0.25 layers and half layers for perimeters (SKIN feature in skeinforge). That was overkill. Perimeters are too fat and it takes time. Didn't use any support.

Motivation

The model can decorate something like thingiverse.com/thing:31284 of which I plan to release a new version sometimes soon.

The reason why I made this, is that I was puzzled that the printer I own (Felix) did not make the arch in the Make Mag test. Last spring I got mine assembled out of the box and never did any calibration or tweaking except moving the print bed closer to the nozzle. And yes, the torture test does print much better than in the Make Mag article as you can see in the picture.

I think that the Make Mag test was well done and quite serious. However, a better test (but way more expensive) would have involved giving the printing to one single person who also somewhat understands how to configure slicer settings. Btw. I just took the vendor supplied "normal" style, slowed down the 1st layer and activated the skin feature.

Morale: Slicer settings do make a difference. A well calibrated printer could even do better.

Extra benchmarking

- The lettering
- Roof over underneath

... both are not exactly glorious. My three year old RapMan did horizontal roofs much better. That lets me suggest that slicers should have an option to deal with the 1st roof layer. Lettering is hard and only a slicer that knows about small isolated regions could maybe deal with it.
