Quickly iterate your prototypes to verify your designs and catch flaws sooner using this "prosumer" desktop 3D printer. Use this printer to rapidly prototype display or example models. The MakerBot Replicator 2 is inexpensive, easy to use, and unlike the other 3D printers at think[box], you can run it yourself. If you don't need a stronger functional prototype, or the additional accuracy found in the Fortus 3D printers, a MakerBot Replicator 2 may be the 3D printer for you.
The 3D printer takes STL files, the most common 3D file format. When exporting STL files from your modeling software, if you get an option to select a resolution, there is no need to go smaller than 0.001 inches. The resolution of finished parts on the MakerBot is not finer than this, so increasing the STL resolution beyond this won't result in increased part resolution.
The material used is plastic called PLA (Polylactic Acid). Material properties such as Tensile Strength and Flexural Modulus vary widely with exact composition. For functional prototypes, it is recommended that you use a different 3D printer. Colors stocked include red, orange, yellow, green, blue, purple, white, two grays, black, and translucent natural. Visit think[box] to verify your desired color is in stock. If you would like to bring in your own material, please see a think[box] staff member. Estimate your costs based on the number of cubic inches of modeling material your part will use. Final costs are based on the weight of material you use. A student worker will weigh your desired spool before and after you use the 3D printer and calculate the price based on the difference in weight. Prices are listed below (see explanation of pricing rates):
|Material||Regular Price||Undergraduate Price|
|PLA||$0.19 per gram||$0.15 per gram|
Build envelope (XYZ): 285 x 153 x 155 milimeters (11.2 x 6.0 x 6.1 inches)
MakerBot's advertised minimum step height is 100 microns (about 0.004 inches). Your results may vary based on the settings you choose and the geometry of your part.
