One of the easiest machines in the lab to use, this Fused Deposition Modeling (FDM) 3D Printer rapidly prototypes parts and even entire assemblies out of white ABS plastic. This is no hobby-grade desktop machine; the Stratasys Fortus 400mc will pleasantly amaze you with its fine resolution, good finish, and strong intra-layer bonds. Thanks to the support material, which provides a foundation for overhanging parts, designers don't need to worry about positive drafts, holes in sidewalls, and other manufacturing details.
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 is 0.005 inches, so increasing the STL resolution much beyond this won't result in increased part resolution.
Please note that Polycarbonate parts are only printed on Fridays due to the 5-hour setup time, so there is an additional waiting period if you select this material.
Material properties such as Tensile Strength and Flexural Modulus are available in the material datasheets. At this time the only available color of these plastics is white (ivory). Costs are based on the the total number of cubic inches of modeling material your part will use, with rates published below (see explanation of pricing rates):
|Material||Slice Height||Regular Price||Undergraduate Price|
|ABS: Ivory||0.010 inches||$32.00 per cubic inch||$11.75 per cubic inch|
|Polycarbonate: White||0.010 inches||$36.00 per cubic inch||$13.25 per cubic inch|
* Regular price is a guide price only, actual cost may vary depending on complexity of build. Contact Dr Malcolm Cooke (email@example.com) with questions.
Build envelope (XYZ): 406 x 355 x 406 milimeters (16 x 14 x 16 inches)
Layer thickness is 0.010 inches. Parts are produced within an X-Y accuracy of ± .005 inches, however accuracy is geometry dependent. Achievable accuracy specification derived from statistical data at 95% dimensional yield.
