3D printing is an additive manufacturing process that allows for the creation of real-world, tangible objects from 3D virtual models. MakeICT maintains the following 3D printers:
Machine Access Policy
Use of the 3D printers requires authorization from an approved peer-authorizor or attendance in a 3D printer workshop that includes authorization.
- Any member who has been authorized to use the 3D printer may peer-authorize other members
- Authorization 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
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.
Note: This process is under development and may change. Check back here for updates if something changes.
Slicing is the process of converting an STL file to the G-Code required to run the printer.
Any slicer with an appropriately configured profile can be used to generate G-Code to run the machines. We have setup Slic3r with profiles for each machine on the design computer in the Fab Lab, and are working to configure the same for Cura. These profiles are available on the Slicer Profiles page on this Wiki.
Slic3r has native support for uploading to Octoprint, just hit the 'Upload to printer' button in the 'Plater' tab. In Cura just export the G-Code file and upload it using the file browser in Octoprint.
When slicing, be sure to use the correct profile for the machine you intend to print on. G-Code generated for one machine WILL NOT work properly on the others.
Each printer can be run using Octoprint. Thorough instructions on this interface can be found on the Octoprint page. The username and password are 'maker'.
The printers can be reached at the following addresses while connected to the network at MakeICT:
- Ultimaker 2: ultimaker.makeict.org 192.168.9.31
- Rostock Max V2: rostock.makeict.org 192.168.9.32
- Creality CR-10: creality.makeict.org 192.168.9.33
- Prusa i3 MK3 prusa.makeict.org192.168.9.34
To run a print: select your file and click the print button.
General Use Tips
- Always watch the first layer of a print to make sure that it sticks to the bed properly.
- Check material before starting a print. Make sure it is the correct type, and that there is enough to complete the print.
- When your print is finished, do not immediately turn off the power; wait until the nozzle has cooled. The Ultimaker and Rostock have actively cooled heatsinks on their hotends, and if power is cut before the nozzle is cool the filament can melt higher up than intended and cause a jam.
- Be careful when removing prints. The glass beds are fairly durable, but can be cracked with excessive force. No hammers, mallets, or other bludgeoning devices are to be used for print removal!
- G-Code files generated for one printer should never be used on another. Re-run the slicer with the appropriate profiles for the machine that is being used
- Abrasive materials require hardened nozzles to print. DO NOT print any abrasives with the regular brass nozzles!
