We have a very expensive (but effective) commercial system that smooths parts.

We also bought one of these on Kickstarter to see how it works.

That's pretty impressive work. I like your car project and how you are going to print the class' work.

We've ended up buying a printer and are currently getting to know it. It prints on a perforated surface. Initially we had problems with the base of a model curling up, but traced that to a misaligned platform. Now all seems to be well.

I won't use ours for class projects. Some of my seniors are likely to print components for their individual projects should the need arise.

Keep up the good work. You've certainly got the hooked.

Printed 100 wheels off today... Looks like I finally got my bed pretty darn level.



Pile of wheels and my sample with 'em glued on.



Starting the printer unit with my 8th graders, so hopefully bigger and more-better-er things to come.

Tech 2's practice project, first batch.





They drew them up, exported the .stl, repaired it in Netfabb, and a few of them played a bit with Repetier. Couldn't get it to install on all of the computers though so we loaded them all in one file to generate the code.

Any good suggestions for a "big" project for grade 8's? They don't have a ton of Sketchup experience but I'd like something that will stretch 'em a bit. Current plan is they will have to design some mechanical part that is made up of at least three seperate printed parts that fit together (can use nuts/bolts/etc) and does "something".

How about a plastic hinge? You could then use it on something.

Have them design a bridge that can hold a one pound weight.

I've been running a Lulzbot AO-101 for a couple of weeks. I've found that the Slic3r which is included with Pronterface is kinda old and shitty compared to the latest & greatest. Mine was 0.7.1 versus the 0.9.9 I downloaded.

The 0.7.1 was not very good at overhangs and bridges, not very good at all. I use the 0.9.9 to create gcode now.

Before I lose this link.

A pretty cool parts finisher: http://www.kickstarter.com/projects/...intsexpresscom

And also, filament extruder contest winner. I believe several companies, including Aleph Objects is going to be selling a pellet to filament extruder kit based on this design. Will save lots of money.

I ordered one to try out. I don't think most Maker level system users are interested in our $25,000 parts finisher.


You guys that are working with heated acetone are insane.

Finished gluing wheels on today.













Some of them followed the instructions great, a few didn't and their wheels didn't fit in the wheel wells... Mostly they turned out pretty good!
