We own an Objet Eden 250, a Stratasys Dimension SST 1200es, a Stratasys Dimension uPrint, and a few DIY 3D Printers. The Dimension printers print in ABS plastic using fused deposition molding while the Objet Eden printer deposits a UV curable resin.
While the printers are free of charge to use for ME senior design students, keep in mind that many times, another fabrication method is preferred over 3d printing as 3d printed parts are quite costly for the lab and offer limited material choices. That said, 3d printers can be a great tool for smaller, intricate part as their resolution is quite good.
If you are looking for our free to use 3D printers, you want the consumer grade 3D printers.
If you need a part printed for senior design or a research lab on campus submit your file in STL format to Clint Rinehart using THIS page. Otherwise fill out THIS form and submit your file in STL format to Clint Rinehart using THIS page. Also, this should be filled out by your finance department if you are in a Georgia Tech department other than ME.
The lab reserves all rights to reject your parts if we deem it better produced by another method.
Stratasys Dimension SST 1200es:
- Cost: $17/cubic inch, varies by project
- Find the Manual Here
- Prints ABS plastic in a variety of Colors. Parts are hard, strong, and can be drilled/tapped/sanded/etc.
- Support Material is dissolved away in a base bath after printing
- Build size is 10x10x12 inches (this is a maximum, please take care to limit build size)
- When designing, allow .5mm gap for moving parts and 1mm resolution for details (like text)
- Layers are built up at a resolution of .254 mm
Example parts this printer has printed:
Stratasys Dimension uPrint:
- Cost: $28/cubic inch, varies by project
- Similar to the Dimension 1200ES.
- Prints ABS plastic in a variety of Colors. Parts are hard, strong, and can be drilled/tapped/sanded/etc.
- Support Material is dissolved away in a base bath after printing
- Smaller Build Size: (8x6x6in)
- Layer Thickness: .254in
- When designing, allow .5mm gap for moving parts and 1mm resolution for details (like text)
Objet Eden 250:
- Cost: $27/cubic inch, varies by project
- Deposits UV Curable Resin which can be semi transparent or opaque. NOTE: As parts are UV cured they do not weather well and become brittle if exposed to sunlight
- Support Material is scraped away with water afterwards (actually a more intensive process than the dimension)
- Build size is 10.2×10.2×7.9 inches (but you parts should be wayyyy smaller)
- Print Resolution: X-axis: 600 dpi: 42 µ ;Y-axis: 300 dpi: 84 µ ; Z-axis: 1600 dpi: 16 µ
- Great finish on Z facing layers.. good finish on x/y facing layers

The lab also maintains two DIY printers, free for student use. They are the Thing-O-Matic from Makerbot Industries, and the Ultimaker from the Netherlands. Pictures are below
