3D Printing – Architecture Workshop Guide

Use the workshop 3D printers to produce architectural models or technical components. This guide outlines the basic workflow—from preparing your model to starting the print.

Available Printers

The workshop provides two printers:
• BambuLab P1S – build volume 25.6 × 25.6 × 25.6 cm
• BambuLab H2D – build volume 35.0 × 32.0 × 32.5 cm

Make sure your model fits within these dimensions. Larger models should be divided into multiple parts.
A single print job must not exceed 8 hours, so longer projects must be split across several print plates.

Materials

Standard printing material is PLA, suitable for most architectural and presentation models.

Commonly used materials include:
• Polymaker PolyTerra PLA (various colors)
• eSun PLA+ for finer or more durable parts

You may bring your own filament. Recommended brands are BambuLab, eSun, or Polymaker.
Wood-filled filaments are not allowed, as they cause excessive nozzle wear.

Model Preparation

Prepare and slice your model in Bambu Studio.
Arrange objects on one or multiple plates if necessary.
1. Export your model from your CAD software (e.g., Rhino) as .3mf or .stl.
2. Ensure the mesh is clean and closed.
3. Set appropriate layer height, supports, and material settings (0.4 mm nozzle).
4. Arrange objects on one or multiple plates if necessary.
5. Slice the model and inspect critical areas such as overhangs or unsupported parts.
Note: Smaller layer heights significantly increase print time.

Export the project file (.3mf) and send it to:
termine-digital@fawa.uni-stuttgart.de

Include the material, color, and whether you bring your own filament.
The print time shown in the slicer is used for scheduling.
Costs
Total price is calculated as:
(material consumption × material price) + (print time × service fee)

Example
48 g × €0.04 + 3 h × €0.50 ≈ €8

If you bring your own filament, you only pay the service fee based on print time.
Printing Procedure

On the day of your appointment:
1. Check in at the workshop counter.
2. Load your file on the designated workstation.
3. Verify the settings and material.
4. Start the print.
Stay nearby at the beginning to ensure the first layer adheres correctly, and check the printer periodically during the process.

After completion, inform the staff. The object will be removed from the print bed and the printing costs will be calculated.

Technical Notes
A printable model must:
• consist of a closed mesh
• contain no open edges or geometry errors
Remember that supports increase print time and cost, so use them only where necessary.
Safety
The printer head and bed reach high temperatures.
• Do not touch hot or moving parts.
• Never place hands inside the printer while it is operating.
If problems occur (e.g., filament jams or print errors), inform the workshop staff immediately.
