Critical surface
Keep visible surfaces away from supports and inaccessible finishing areas.
RESIN / ORIENTATION & SUPPORT
Orient resin prints for surface quality and reliable production
Understand suction force, tilt, supports, surface marks and accuracy when preparing a resin-print job.
PEEL · SUCTION · GRAVITY
Every layer must survive peel force
In bottom-up resin printing, each cured layer must separate from the vat film without detaching from the plate or supports. Large cross-sections and sealed cavities can increase suction and lead to detachment, fracture or distortion.
Tilting can smooth cross-section changes, reduce stepping on curves and move support marks to hidden surfaces. There is no universal best angle because time, support count and accuracy trade off.
ORIENTATION DECISION
Choose orientation from five factors
Cross-section
Avoid sudden area changes and resin-trapping cavities.
Load direction
Functional parts must account for layer-direction strength.
Accuracy
Holes, mating faces and Z dimensions may need allowance or machining.
Build time
Z height determines layer count and time.
SUPPORT STRATEGY
Supports must hold the part without destroying detail
- 01
Build a stable raft
The raft must anchor the build and carry peel loads.
- 02
Place primary anchors
Support islands and major mass before fine details.
- 03
Distribute load
Avoid concentrating load at one small contact.
- 04
Inspect layer preview
Find islands, cups, sudden area jumps and undrained cavities.
- 05
Plan removal and finishing
Choose acceptable mark locations and finishing allowance.
PRINT-READY BRIEF
What a resin printing service should ask
- Actual size and file units.
- Visible surfaces, critical detail and no-mark zones.
- Part function and loads.
- Whether the part should be hollow or solid and where drainage is allowed.
- Cleaning, post-cure, sanding, priming and painting.
- Quantity and deadline for batch planning.
