New class: SketchUp for 3D Printing

We are offering a class on how to use Google’s free 3D program SketchUp. SketchUp is not the most powerful CAD program out there, but its intuitive design and price make it a great start if you are curious about conjuring solid objects out of plastic and bytes.

This class will run Saturday, February 2/26 from 10am to 3pm at Hive76

You will learn:

  • How to make simple stuff in SketchUp
  • How not to ruin a model by poking holes in it, what “manifold” means.
  • The basic process of FDM 3D printing
  • The limitations of the Makerbot

And most importantly, you get to print and take home a thing!

SloateBot: Prusa Mendel Lives!

The Prusa Mendel build is finally complete! Here’s a Stanford Bunny:

PLA bushing sliding on precision ground 8 mm rods is actually quite smooth movement. I don’t think it can go as fast as the original Sells Mendel (which was ball bearings sliding over the rods), but it’s only half the printed parts and the z-axis is much smoother motion too. I will try oiling or greasing the bushings to try to get smoother and faster motion without losing steps. So definitely some tradeoffs but overall a super awesome bot. The Prusa is also fully parametric and entirely made from OpenSCAD. All sources are available on github FTW.

As this is the first bot I built that I actually own, I named this awesometown after my HS science teacher, Mr. Sloate, who really got me into Biology and now, robotics for Biology.

What will we print next?

Hive76 Celebrates the Birth of Our Third 3D Printer!

Adam K. works on getting axis movement on the RepRap Huxley

Back in 2009, we ordered our first 3D printer, the MakerBot Cupcake. Since then, we’ve become pros at fixing, modifying, and mostly breaking it. We’ve even created new, awesome products for it which have been adopted by a good portion of the 3D printing community, and even sold by MakerBot themselves.

Shortly after completing our Makerbot, once-member fynflood decided to start building the RepRap Mendel, which is the 2nd generation of the RepRap Project’s 3D printer. He started by printing all of the pieces on our MakerBot, which took over 20 hours to complete, and gathered all of the required hardware with help from many of our members. A printer was born out of Hive76, and life was good. A few months later, there was a post on the reprap aggregation pipe about a new iteration of the reprap, called the Mendel Mini (now the RepRap Huxley), which has a similar build volume to the MakerBot, but can be assembled for under half the cost. Fynflood set out to print the parts on his Mendel, while I gathered all the required hardware and electronics. After a few months break over the summer, and a few more months being busy with the Holidays, the Huxley is now complete! Our printer’s baby made a baby!

At this very moment, we have 2 MakerBots and the Huxley all going at the same time at the space! If any more printers show up, we’ll probably have to start giving away USB Typewriters just to make room! Really, it’s an exciting time to be printing at Hive76, so if you have any interest in learning how 3D printers work, or even building your own, come by for open house on Wednesdays and check out all the awesome things we’re making!

Hit the jump for a few videos and images from the first few prints!
