3D Printing File Preparation

 

Beginner

Use an existing file from Ready-To-Print 3D Designs on our Resources page.

Or follow these steps:

  1. Go to www.thingiverse.com
  2. Choose a model
  3. Download as an .stl file
  4. Submit file

 

Beginner Plus

Review your file before printing to check size.

  1. Open Cura app * (available on all public computers, or download the software to your own)
  2. Load your model file
  3. Resize/scale, if desired
  4. Save model as an .stl file
  5. Submit file

*Instructions for downloading Cura to your own computer are available on the LulzBot website.

 

Intermediate to Advanced

Modify an existing file or create your own using any 3D modeling software.

Example:

  1. Go to www.tinkercad.com
  2. Choose a model
  3. Export as an .stl file
  4. Submit file

 

Frequently Asked Questions

File Format

Export your model with an .stl extension. (STL = stereolithography) We cannot accommodate any other file format. Only file submissions under 32MB will be accepted.

Material

We use PLA (Polylactic Acid) filament in our printer, made by VillagePlastics. We will only print with filament we have purchased.

Colors

Your model will be printed in a single color of your choice from the variety we offer. Color selections will vary throughout the year, based on usage and demand.

Dimensions

The maximum size the Lulzbot Mini can print is 152mm x 152mm x 158mm (6in x 6in x 6.2in). However, the time it will take to complete a print job will factor into the maximum size of an item. Print jobs will be limited by both the maximum size and the maximum amount of time needed to complete.

Units

Please build your model in millimeters or convert to millimeters before submitting the final file. You can double check if your file is the right size for printing by downloading the Cura software from LulzBot. When prompted, select LulzBot Mini as the printer and VillagePlastics PLA as the filament.

Resolution

The default settings are: medium resolution, 0.21 mm per layer with 10% infill. These settings are sufficient for most models. If you need something different please specify in the Special Instructions box on the 3D Printing Request.

Supports and Rafts

Some models will not print well without supports or rafts. Supporting structures are usually needed if the design includes a section that protrudes from the base at more than a 45 degree angle. Occasionally, a raft must be added to a design to help it adhere to the printer bed. Library staff will use their best judgment in adding supports or rafts to your model. The library will not be responsible for removing supports or rafts from a print job.

 

Where to get Models

You can find resources to download existing models, customize models or create your own on our Resources page.

 

Submitting Your Model

Once your model is ready to be printed, submit a print request on our 3D Print Request form and upload your .stl file. We will contact you if we have any questions about your file. We cannot guarantee a file’s success. Once your job is complete you will be notified via email. You may pay for and pick up your item from the circulation desk. We accept cash, check or charge. We will hold print jobs for 14 days. Items not claimed in 14 days will become the property of the library.
