3D Printing

Available equipment

We have 3 Lulzbot Mini V2, 2 Lulzbot Workhorses, and 1 Lulzbot Pro available to use.

Lulzbot Mini:

The LulzBot Mini is a high-performance desktop 3D printer that’s perfect for home users, makers, designers, engineers, architects, and anyone looking for an easy-to-use desktop 3D printer. It’s small and compact, great for small prints. We have also equipped the printer with specialty magnetic beds, allowing for increased bed adhesion and ease of removable after printing.

Lulzbot Workhorses:

The workhorse is a reliable and bigger 3D printer compared to the mini. With the larger volume, the workhorse allows for prints of bigger volume. We have also equipped the printer with specialty magnetic beds, allowing for increased bed adhesion and ease of removable after printing.

Lulzbot Pro:

The LulzBot Pro is an industrial desktop 3D printer that provides large, multi-material, and soluble support printing.

Rules for 3D printing

At the makerspace, we provide 3 types of filament: TPU, PLA and PETG. We will print ONLY with these 3 filaments, no exceptions, due to concerns of toxic fumes and nozzle head capability.

Our printers are ONLY compatible with 2.85mm filament.


1. Write down JHED, grams, and print time.
2. Use one printer at a time.
3. Ensure the first layer sticks before leaving the area.
4. Ask a tech to assist with filament change and print removal (unless there is a magnetic bed attached).
Filament Usage
1. Max 100g of filament per print.
2. For larger prints, contact the makerspace manager for approval.
3. Each student is permitted 500g of free filament a semester.
4. Surpassing this limit, guests are expected to provide their own filament

3D modeling

3D modeling is the process of developing a digital drawing in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space. The current popular 3D modeling softwares are as follows:

If you’re still interested in 3D printing but have no experience modeling, you can find models available online for free at GrabCAD, Printable or Thingiverse. Most likely what you are looking for is already designed and uploaded onto one of these 2 sites.

Splicing Software

Slicing programs is a computer software used in 3D printing processes for the conversion of a 3D object model to specific instructions for the printer. In particular, the conversion from a model in STL format to printer commands in g-code format in fused filament fabrication and other similar processes. The slicer first divides the object as a stack of flat layers, followed by describing these layers as linear movements of the 3D printer extruder, fixation laser or equivalent. All these movements, together with some specific printer commands like the ones to control the extruder temperature or bed temperature, are finally written in the g-code file, that can afterwards be transferred to the printer.

As our 3D printers are from Lulzbot, we use Cura Lulzbot as our slicing program. This is a proprietary version of Cura, the most popular slicer and also free.
