Design advice
1/ Hollow Large Parts and Add Drain HolesLarge solid cross sections create strong peel forces as each layer separates from the vat, which can distort or fail the build. Shell parts to 1.5 to 2 mm walls and add at least two drain holes so trapped resin can escape.
2/ Mark Your Cosmetic FacesSupport contact points leave small marks after removal. Tell us which surfaces are visible, and we will orient and support the part on hidden faces to protect finish quality.

DLP 3D Printing Materials

Our DLP resin portfolio covers castable wax for investment casting, dental model resins, tough engineering resins, optically clear resin and high-temperature resin for heat-exposed test parts.
Castable Wax Resin
A wax-filled photopolymer for lost-wax investment casting. It captures fine filigree, prongs and textures, then burns out cleanly with minimal ash. That makes it a reliable pattern for jewelry, dental frameworks and small precision castings.

3D Printing/01
Move from CAD to physical part in days. Validate form, fit and function with MJF, SLA, DLP and other additive processes, then iterate quickly before committing to tooling.
3D Printing Solution
Vacuum Casting/02
Need 20 to 50 production-quality parts? Vacuum casting from silicone molds gives near-molded surfaces and a wide range of urethane properties for pilot runs and market trials.
Vacuum Casting Solution
Injection Molding/03
When volumes reach the thousands, injection molding delivers the lowest unit cost and tight repeatability. We help you move from printed parts to production tooling without redesign surprises.

Why Choose Us

Enstark helps engineers and product teams turn detailed designs into precise resin parts, combining industrial DLP printing with hands-on engineering support and consistent quality control.

/01
High Detail Resin Parts
Fine layer heights and precise UV projection reproduce thin walls, sharp edges and delicate textures with minimal visible layer lines. Your parts arrive with the surface quality needed for fit checks, casting patterns and presentation models.
High Detail Resin Parts
/02
Fast Lead Times
DLP cures each full layer at once, so small parts print quickly and many fit into a single build. Standard orders ship in about 3 to 5 business days, keeping your design reviews and product launches on schedule.
Fast Lead Times
/03
Engineering Driven Support
Our engineers advise on resin selection, part orientation and support placement before printing starts. When a feature is better suited to SLA, MJF or CNC machining, we tell you upfront to save cost and time.

What's DLP 3D Printing ?

Digital Light Processing (DLP) is a vat photopolymerization process. A projector with a digital micromirror device flashes an image of each full layer onto liquid resin, curing the whole layer at once. Parts are then washed and UV post-cured, producing smooth, highly detailed resin components.

✓Material traceability
✓Batch consistency for production runs
✓In-process quality control
✓Dimensional inspection before shipment
✓Tolerances up to ±0.1 mm
✓Final inspection before delivery

Pros and Cons of DLP 3D Printing

Pros of DLP 3D Printing

Extremely Fine Micro-Detail

Extremely fine detail, with layers down to 25 µm and sharp feature resolution.

Ultra-Smooth Surfaces

Smooth surfaces with barely visible layer lines, ideal for appearance models.

Fast Layer Curing Speed

Fast builds when many small parts are batched together on the build plate.

DLP 3D Printing Process

Cons of DLP 3D Printing

Smaller Build Envelope

The build volume is smaller than SLA or MJF systems.

Resin Brittleness & UV Sensitivity

Most resins are more brittle than nylon and can degrade under prolonged UV exposure.

Support Witness Marks

Supports leave small contact marks that require delicate sanding.

Frequently Asked Questions
What is the difference between DLP and SLA?

Both cure liquid resin with light. DLP cures a full layer at once with a projector, while SLA traces each layer with a laser. DLP is usually faster for small, detailed parts, and SLA is better for large resin parts.
