Bed fit and batch layout
Check a rectangular part and estimate a grid of copies, including gap, brim and edge margin.
Results
- Fits without rotation
- Yes
- Fits after 90° rotation
- Yes
- Parts without rotation
- 20 count
- Parts after 90° rotation
- 20 count
- Best rectangular grid count
- 20 count
Method
Usable bed = bed − 2 × margin. Footprint = part + 2 × brim. Each axis count = floor((usable + gap) ÷ (footprint + gap)); test both orientations.
Worked example
Example inputs
- Bed width
- 220 mm
- Bed depth
- 220 mm
- Part width
- 40 mm
- Part depth
- 30 mm
- Bed edge margin
- 10 mm
- Gap between parts

Calculated outputs
- Fits without rotation
- Yes
- Fits after 90° rotation
- Yes
- Parts without rotation
- 20 count
- Parts after 90° rotation

- Best rectangular grid count
- 20 count
How to read the result
With these example inputs, Best rectangular grid count is 20 count. Use that value for the setting or decision named above, and read the other outputs as supporting checks.
Common mistake
Do not leave Bed width at the example value of 220 mm unless it matches your own measurement.
Assumptions and limits
Rectangular bounding boxes only. Mixed rotations, nesting, clips, purge towers and sequential-print clearance require a slicer check.
