Architects can turn a Revit, SketchUp, or Rhino model into a crisp physical scale model by exporting to STL, setting a print-friendly wall thickness, and choosing SLA for detail or FDM for larger massing. The result communicates a design to clients far better than a render. Here is the model-making workflow from CAD to a presentation-ready model.
Key Takeaways
- Export to STL at the right scale; check minimum feature and wall sizes.
- SLA for fine facades and detail; FDM for large massing models.
- Split large buildings into sections and assemble — bigger than any single build plate.
- Finish with priming and paint for a presentation model.
- Near Ahmedabad? Fast local turnaround for studio deadlines.
How do you prepare an architectural model for printing?
Decide the scale (e.g., 1:200), then verify the smallest features (mullions, railings) are still printable — thicken anything below the process minimum. Make walls solid enough to survive handling. Export each material/colour group separately if you plan to paint. Our file checklist covers a clean export.
Which process for which model?
| Model type | Process | Why |
|---|---|---|
| Detailed facade / interior | SLA | Crisp fine features |
| Massing / urban block | FDM | Cost-effective at size |
| White presentation model | SLA + paint | Clean monochrome finish |
How do you finish a presentation model?
Sand seams, prime, and spray-paint for a uniform architectural white or material-accurate colours. Sectioned models are glued and seam-filled. For the studio''s broader uses, see additive manufacturing in architecture.
Frequently Asked Questions
How big can a model be?
Effectively unlimited — we print in sections and assemble. Tell us your overall size and scale.
Can you print in presentation white?
Yes — white resin/FDM, or printed then primed and painted. Send your model.
