Projector-cured resin for crisp details and efficient small-part runs.
Digital Light Processing (DLP) solidifies an entire layer of photopolymer at once using a projected image. Compared with point-by-point laser curing, DLP often delivers faster layer times on compact parts while maintaining high XY resolution.
Digital Light Processing cures a whole resin layer in one projected image instead of tracing it with a laser. Compact, detailed parts and small batches therefore leave the vat faster than a point-by-point SLA scan on the same plate.
AIHFABS quotes DLP for jewelry-scale detail, small housings, and repeat visual lots. If you need a very large resin platform, SLA may still be the better envelope.
XY sharpness is high; the live envelope depends on the projector cell assigned to the job.
From 48 hours
±0.2 mm on supported geometry
Varies by machine; typical desktop-to-mid format plates
Smooth as-built; vapor polish or coating available
Required on overhangs
High-resolution modeling resins plus tough, flexible, and qualified biocompatible grades.
As-cured skins are already smooth. Tinting and light sanding are the usual extras.
Default deliverable after IPA wash and UV. Support scars dressed on request.
Light sanding on flats and optional tint for presentation models.
Coat on transparent or high-gloss show parts after the post-cure.
DLP and LCD both flash a full layer. DLP uses a projector; LCD uses a masked LED array.

Each slice is projected onto the resin vat, curing a full layer simultaneously.
The build plate rises and fresh resin flows beneath for the next exposure.
Supports anchor delicate features until the green part is washed and UV post-cured.
Optional tinting, sanding, or clear coating completes the visual specification.
Parts are nested for a single exposure time that still holds the smallest feature. Over-packing a plate can soften edges.
Wash, post-cure, and support removal follow the same resin SOP as SLA. Biocompatible grades need a qualified resin note on the PO.
Think in pixels and minimum cure thickness, then nest the lot.
| Feature | Recommended practice |
|---|---|
| Min feature | Stay above the resin’s published minimum; knife edges often fail to cure. |
| Nesting | Small batches share a plate — keep a common Z height when you can. |
| Environment | Tell us about UV, chemicals, or skin contact so we pick a durable grade. |
| Supports | Overhangs need anchors; mark faces that cannot show witness marks. |
Selective Laser Melting (SLM) is a powder-bed metal additive process. A high-power laser scans each cross-section of your CAD model, melting metal powder that solidifies into a dense part.

DLP exposes a resin layer using a projected image, while SLA traces the layer with a laser. Compact, detailed parts and repeated visual lots are useful DLP candidates. For larger models, review the available build envelope rather than assuming the same machine or resin suits both routes. Compare the smallest required feature, part size, resin properties and support-facing surfaces before selecting the process.
For miniature housings, identify the walls, holes and mounting interfaces that determine fit. For fine presentation models or master patterns, define the cosmetic face and the detail that must survive cleaning and finishing. Approve a representative sample for the intended visual or assembly requirement before releasing a repeated lot.
Pixel size is not a whole-part tolerance. Small text, slots and pins also depend on exposure, resin, orientation and post-curing. Identify the smallest functional feature and distinguish readable decoration from a dimension that must mate with another part.
Small repeated parts can benefit from a planned build layout, but supported faces still need cleanup. Mark the cosmetic side, provide drainage for hollow features and discuss how fragile details will be handled after support removal.
Confirm resin grade, quantity, surface requirements and the finished dimensions of small mating features. Validate a sample before releasing a repeat batch with fine clips, thin walls or miniature lettering.
