3D Printing
The UVM FabLab offers the use of its 3D printers to help students rapidly prototype small parts that would otherwise be difficult to manufacture or acquire. Keep in mind that FabLab resources can only be used for school-related projects and that, like any manufacturing process, 3D printing has physical and cost limitations that differ by machine.
3D Printing Guidelines
The following guidelines will help you determine whether your design is suitable to print in the FabLab:
- Your part must not be too small: Features smaller than 0.4mm (.016 inches) will not print reliably.
- Your part must not be too big: It should not use excessive material or time and must fit within printer dimensions.
- Your part must be structurally suitable: Avoid delicate features or large unsupported sections.
- Your part must comply with policy: We do not print weapons, weapon parts, drug paraphernalia, or copyrighted designs.
If your part is rejected for any of the reasons above, you are always welcome to modify and resubmit it. Our Fabbers are experienced and can provide feedback throughout your design process.

About Extrusion-based 3D Printing
3D printing is a type of additive manufacturing, the opposite of traditional fabrication where material is removed. These machines heat thermoplastic filament (PLA, ABS) and extrude it layer by layer. A 3D file is processed in slicing software to create toolpaths and internal infill structures that strengthen the part.
Some extrusion printers can print with soluble or breakaway supports, enabling more complex geometries and improved surface quality.
About Stereolithography 3D Printing
Stereolithography is another additive manufacturing process that uses a laser to cure liquid resin into solid plastic layer by layer. This produces highly detailed parts with isotropic properties. Materials include grey, clear, white, and wax resins for casting.
Important: 3D printed parts are not free. The FabLab sponsors coursework, senior design, and some clubs using approved materials. Engineering senior design is billed per ticket, except FormLab resin printers (teams must supply cartridges/tanks). Additional prints require payment via UVM chartstring.
Professional manufacturing options are available both on and off campus. If your job is too large or time-intensive, consider alternatives such as the Howe Library, IMF Labs, Shapeways, or Generator Makerspace. If there is a strong reason to print in the FabLab, contact fablab@uvm.edu.
