About
3D printing is an additive manufacturing process that allows for the creation of real-world, tangible objects from 3D virtual models. MakeICT maintains three separate 3D printers, a RepRap Prusa Mendel, an Ultimaker 2, and a Rostock Max V2. Full details and specifications can be found on the individual equipment pages.
| RepRap Prusa Mendel | Ultimaker 2 | Rostock Max v2 | |
|---|---|---|---|
| Build volume | 180 x 180 x 100ish mm | 223 x 223 x 205 mm | 280 (circle) x 375 mm |
| Filament types | PLA | PLA, ABS, CPE | PLA, ABS |
| Filament diameter | 1.75 mm | 2.85 mm | 1.75 mm |
| X/Y resolution | 0.125 mm | 0.125 mm | 0.1 mm |
| Z resolution | .0039 mm | 0.02 mm | 0.0125 mm |
| Nozzle diameter | 0.35 mm | 0.4 mm | 0.5 mm |
| Heated bed | No | Yes | Yes (it's slow!) |
Machine Access Policy
Use of the 3D printers requires attendance in a 3D printer certification workshop or certification from an approved peer-certifier.
- Any member who has been certified to use the 3D printer may peer-certify other members
- Certification instruction must at least include
- Fundamental knowledge of each printer's working principles
- Proper use and control of each printer
- Software workflow
- How to change filament
- How to pay for material
Filament Fund
Printing with filament provided by MakeICT costs $0.04 per gram. After printing, please weigh your print using the provided scale and put the appropriate amount of money in the filament fund jar. If you have any requests for new colors/types of filaments, you can write them on the same jar.
General Use Tips
- When changing from a filament that prints hotter to one that prints cooler (e.g. ABS to PLA) you should do a cold pull to remove the old plastic that is lining the melt chamber. Otherwise there will likely be problems with underextrusion due to the unmelted plastic.
