Getting a Model 2 Beta
NOTE: THIS PAGE CONTAINS FILES RELATED TO THE BETA RELEASE OF THE MODEL 2. FOR UPDATED FILES FOR THE FINAL RELEASE, GO TO THIS PAGE: Fab@Home: Model 2 Overview.
There are three options for getting a Model 2 Beta fabber:
- (Coming Soon) You can buy a fully assembled unit from NextFabStore.com
- (Coming Soon) You can buy an unassembled kit from NextFabStore.com which bundles all necessary parts into one package
- You can purchase each component individually directly from the manufacturers
Option 1: Purchasing a Fully Assembled Unit
You can purchase a fully assembled unit from the following vendors: Nextfab
You're done... the system is already built. All you have to do is install the software on your computer and load the appropriate drivers.
Option 2: Buying an Unassembled Kit
You can purchase one of these kits from the following vendors: Nextfab
The acrylic (i.e., the chassis) has already been laser cut by the kit provider and all that is left is assembly. For details on assembly, see the Model 2 assembly instructions
Option 3: Purchasing Individual Components Directly from Manufacturers
Procuring the Mechanical and Electrical Components
You will first need to purchase the components. All components are off-the-shelf and come from 3 vendors (McMaster, SDP-SI, and JrKerr). Use this parts list to gather all the materials.
Laser Cutting the Acrylic Chassis
Once you have the components, you will need to laser cut the acrylic for the chassis. The designs for the acrylic pieces are found in these SolidWorks 2007 files, [1], or DXF files. The files were created for an Epilog Helix 24. To cut on another laser cutter you will need to make your own offsets from the original Model 2 Beta CAD files and adjust the cut compensation offsets for your laser cutter. If you do not have a copy of solidworks 2007 or newer, please post in the google group and someone will make the files for you.
A Single syringe tool is also available here
Assembling the Unit
Now that you have the off-the-shelf components and the acrylic, it is time to assemble the unit. Just like with the kit, follow the assembly instructions, or watch this video
Software
The Model 2 currently uses different control software than the Model 1. The Model 2 Software page gives more detailed documentation. There are two parts to the control software. FabStudio imports STLs and tool files and outputs a series of layers and paths in the form of a fab file. The FabInterpreter controls the printer and converts fab files into motion. Both of these programs are part of a redesign of the software and hardware interactions. This is currently being done by The Cornell Fab@Home Student Project Team. These programs are not in their final form and the underlying code is being rewritten. For more information on the future of the software please visit the future software page once it is complete.
