HOW TO SUBMIT MODELS FOR 3D PRINTING
I will be using a more simplified process in an effort to make 3D printing requests easier for everyone during our school closure.
1. Complete this Google Form – This is where you will submit the 3D model you would like printed. Please fill out all of the information in the form.
2. Monitor the status of your printing request – I use this Trello board to manage all printing requests. You will know whether your model has been printed or if your model had any errors and needs to be redesigned. The Google form collects your email addresses, so I will send you an email as well if there are any issues.
Important Design Criteria + Constraints
1. The build volume of our 3D printers is approximately 8″ x 8″ x 9″. Please make sure your model is smaller than this!
Also, 3D models must have a print time less than 4 hours. If you made a print the same size as the build volume listed above, the print time would be close to 24 hours!
If the size of your model doesn’t matter, I will just scale it until the print time is adequate. If you need your design to be true to size, you will need to redesign your model.**
** If you would like to get an estimate of your model’s print time, view the information below on how to use PrusaSlicer.
2. All 3D models must be student-designed and school appropriate.
3. In order to be printed successfully, your model should adhere to important design criteria. I recommend you watch the short videos in this free course by PrintLab: Designing in Tinkercad for 3D Printing.
You can also look at this 3D Printing Design Rules handout (PDF). We have fused deposition modeling (FDM) printers, so only pay attention to the first row. This handout may be a bit overwhelming for some, and I am working in a simplified version.
Prepare Your 3D Model for Printing with PrusaSlicer
3D Printing is a four step process: Plan, Design, Slice, and Print.
- Always plan out your mode first and take any necessary measurements.
- Design your 3D model using software such as Tinkercad, Onshape, SketchUp for Schools, or Fusion 360
- Export your 3D model (.STL) into a slicing software that prepares the model for printing. We use PrusaSlicer, which is the proprietary software for our Prusa 3D printers. This will tell the 3D printer how to create the model layer by layer. It also gives you an estimation for the print time and amount of filament that will be used.
- Send the sliced model to the printer as a .GCODE file. This file has all of the sliced settings saved, such as filament type and temperature settings.
To help you do Step 3, please download PrusaSlicer to your computer. This link also includes information on the different features and some video guides!
Next, watch the two videos below to learn how to set up and use PrusaSlicer to slice your model.
**You should only use this software for Step 3. When you are ready to share your model for printing, please include the .STL file. Do not export your model as a .GCODE file from PrusaSlicer! I am unable to view your model or see which settings you used. I need to be able to check your model and make sure all settings are correct before I print it.
