What Is Digital Light Processing 3D Printing?
Digital light processing 3D printing is a resin-based process that uses projected light to cure an entire image layer at once. It is commonly selected for small parts that need fine features, smooth surfaces, and consistent detailing.
How DLP 3D Printing Works
A digital projector exposes each cross-section of the part onto liquid photopolymer resin. After each layer cures, the build platform moves and the next image is projected. The part is then cleaned, supports are removed, and the resin is post-cured according to the selected process.
When Is DLP 3D Printing the Right Choice?
Choose DLP 3D printing when small resin parts require crisp features, smooth surfaces, or repeatable detail across a batch. Final suitability depends on resin, dimensions, tolerances, orientation, support strategy, and post-curing.

DLP 3D Printing Design Guidelines
Use these starting guidelines when preparing a model for DLP printing. Final wall thickness, feature size, hole diameter, support placement, and orientation depend on the resin, part geometry, and intended use. Contact Champ3D to confirm critical features during file review.
Design Factor
Recommended Guideline
Why It Matters
Minimum Wall Thickness
≥ 0.6–0.8 mm
Prevents fragile thin sections from breaking.
Fine Detail Features
≥ 0.2–0.3 mm
Maintains sharp micro-level accuracy.
Support Structures
Required for overhangs
Ensures stability during printing.
Hollowing

Reduces resin usage and internal stress.
Drainage Holes
≥ 2 mm diameter
Allows uncured resin to escape.
Sharp Corners

Reduces stress concentration during curing.
Surface Finish and Post-Processing for DLP Parts
DLP parts are cleaned and post-cured before final inspection. Available finishing may include support removal, localized smoothing, sanding, or preparation for painting. The selected finish can affect appearance, dimensions, lead time, and price.

Frequently Asked Questions About
Digital Light Processing 3D Printing
DLP 3D printing is a resin-based process that projects an image to cure a complete layer of photopolymer at once. It is commonly used for small parts that require fine details, smooth surfaces, and repeatable feature quality.
A DLP 3D printing service converts a 3D model into layer images, cures the selected resin layer by layer, then cleans, post-cures, and inspects the part. At Champ3D, customers upload a CAD file, review the quote and options, confirm the order, and receive the finished parts by shipment.
Both cure liquid resin, but DLP exposes an entire image layer with projected light while SLA typically traces each layer with a laser. The better option depends on part size, feature detail, surface requirements, resin, throughput, and equipment.
The page currently identifies STL, OBJ, and STEP. Confirm units, provide a closed solid where required, and use enough mesh resolution to preserve the detail expected in the finished part.
Accuracy depends on projected pixel size, layer height, resin behavior, orientation, support placement, and post-curing. Publish verified tolerance guidance and ask buyers to identify critical dimensions during review.
The current page lists 0.6–0.8 mm as a starting guideline. Required thickness may increase with wall height, unsupported spans, resin, and loading, so critical walls should be reviewed before production.
Supports are usually required for islands, overhangs, and unstable features. Orientation and contact placement affect appearance and dimensions, so keep contacts away from critical cosmetic or mating surfaces where possible.
Drainage holes let uncured resin leave enclosed cavities and support cleaning and post-curing. The page lists 2 mm as a starting diameter, but size and quantity should be confirmed for the cavity, resin, and cleaning method.
DLP can support fit checks, fixtures, housings, and other uses when the resin meets load, impact, temperature, and environmental needs. Review verified material data rather than choosing by color or finish alone.
DLP can support detailed prototypes and repeat orders of small resin parts. Suitability depends on build size, nesting, resin consistency, inspection needs, quantity, and schedule.
Pricing usually depends on volume, dimensions, quantity, resin, orientation, supports, finishing, inspection, and delivery. Upload the final CAD file to the digital light processing 3D printing service to view available options and a model-based quote.
Timing depends on size, quantity, resin, scheduling, post-curing, finishing, and quality checks. Show the production and shipping estimate in the quote or order summary before payment.
Check units, walls, smallest features, cavities, drainage, support-contact areas, critical dimensions, material properties, finish, quantity, and delivery. Mark must-hold dimensions on a drawing and confirm any requirements the online quote does not address.
