Quick answer
A desk-sized house model (1:200 scale) takes 2–4 hours on a standard FDM printer. A detailed presentation model (1:100) takes 6–12 hours. A keychain-sized model (1:500) prints in under an hour.
Time by scale
| Scale | Typical size | FDM time | Resin time | Material |
|---|---|---|---|---|
| 1:500 | 2–4 cm | 30–60 min | 20–40 min | 5–10g |
| 1:200 | 6–10 cm | 2–4 hrs | 1–3 hrs | 20–40g |
| 1:100 | 12–20 cm | 6–12 hrs | 4–8 hrs | 80–150g |
| 1:50 | 25–40 cm | 15–30 hrs | N/A (too large) | 300–500g |
These assume a typical two-bedroom apartment. Larger or more complex homes scale proportionally.
What affects print time
Layer height. 0.2mm layers print twice as fast as 0.1mm. For architectural models, 0.15–0.2mm is the sweet spot between speed and surface quality.
Infill. House models do not need to be solid. 10–15% infill saves material and time with minimal impact on appearance.
Printer speed. Fast printers (Bambu Lab P1S at 300mm/s) can cut the times above in half. Slower printers (Ender 3 at 50mm/s) may take 50% longer.
Supports. Window and door overhangs require support structures that add print time. Tree supports are faster to print and easier to remove than grid supports.
The digital side is instant
The longest part of getting a 3D printed house model used to be creating the 3D model itself — hours of CAD work. Ritn3D generates the model in under two minutes. The STL download is instant. Only the actual printing takes time.
