LulzBot 3D Printer At Our Space

This past fall we had a visitor from the Loveland-based company Aleph Objects, Inc. which makes Lulzbot 3D printers. After the visit, they offered to sponsor us by providing us with a LulzBot AO-100 3D Printer Package.

The printer was basically ready to go – nearly no assembly time and already calibrated. We were printing within 10 minutes of taking it out of the box! For most other printers, it takes many hours to assemble and calibrate.

The LulzBot AO-100 is similar to the MendelMax but with LulzBot’s own printed parts. It prints faster than the Reprap Prusa Mendel we have had at our space since last spring.

Stop by our space in east Boulder on a Tuesday night and chat with us to find out more and perhaps see the LulzBot in action. If you want to use it, become a member and get some instruction from one of our 3D printing gurus. Also, if you are in Denver this Thursday afternoon, you can chat with the LulzBot team and see some of their printers in action at a 3D printing open house, which is being held from 3-6 pm at the 3D Printing Store at 4603 Monaco Street, Denver.

Creating Physical Reality: 3D Printing with the Reprap Prusa Mendel

We now have a working Reprap Prusa Mendel 3D Printer at the space!

3D printing aka additive manufacturing is a process of making three dimensional solid objects from a digital file driven by a computer. Plastic is fed from a reel and heated and extruded onto a surface where it is additively layered to create 3D shapes. Reprap stands for replicating rapid prototyper, i.e. the printer can print its own parts (the plastic ones anyway, with a little care and feeding from a human). Similar to a regular 2D ink printer, you use special software on a computer (Windows or Mac) to design your print, then direct it to communicate the specs to the printer. In this way it is a computer numeric controlled plastic extruder. (I can’t help thinking CNC plastic factory and want to go listen to 90’s music by C+C Music Factory.)

The Prusa Mendel was graciously donated by Eric M and initially had some firmware and extruder problems to sort out. Jim T & Tijlon addressed the issues one by one and got it working properly and dialed in (calibrated). It has been merrily printing away for a couple weeks now and is nearly done spawning new parts for another printer that Jim is making for himself. Jim figures the cost to make a new reprap will be about $500 total, breaking down into about $350 for motors and electronics, $30 for the plastic, $120 for metal pieces + around 100 hours printing time for the plastic.

After Jim gets the second printer working and dialed in, he plans to offer a workshop in late June or early July to show us how to create computer-directed shapes and coax them out of a reel of plastic. The format of the class is not yet set, either a one or two instruction or possibly a series, covering the bases from how to use the Sketchup software, how to export and print in 3D, taking us from design to print. Jim is also planning to print parts for another reprap and offer them for sale, with proceeds to benefit the space.

Joel is also separately working on getting another printer up and working (the blue one in the photo). In other fun new toy news, we also recently had another member, Dixon, donate a CNC machine. We scratched our heads for a while as the parts were lining up a bit wonky, but Tijlon gave it a little encouragement over a weekend and it is now up and running too. More on that in an upcoming post.
