SLA Resin 3D Printing Service Manufacturer
Zhejiang Jiaheng Intelligent Equipment Manufacturing Co., Ltd. is a China-based SLA resin 3D printing service manufacturer and OEM/ODM factory. We cure liquid photopolymer resin layer by layer with ultraviolet light to produce high-precision prototypes, appearance models and silicone mold master patterns for automotive design, consumer electronics, UAV and robotics development.
Our SLA Resin 3D Printing Service covers a maximum build volume of 1.7 × 0.8 × 0.65 meters and a material range that includes ABS-like, off-white, transparent, black and flexible resins. Parts move directly into our surface finishing, vacuum casting and CNC departments when a project requires more than a printed shape.
What Our SLA Process Delivers
Stereolithography builds each layer from a UV-cured photopolymer, so fine features, thin walls and smooth surfaces are reproduced without the visible layer lines typical of filament processes. We use SLA where a part must show true form, fit and finish before tooling is committed.
- Surface quality: smooth as-built surfaces with excellent detail reproduction for appearance review.
- Build envelope: up to 1.7 × 0.8 × 0.65 m, allowing large single-piece models and multi-part nesting.
- Material breadth: rigid, transparent, high-contrast and flexible resins in one service.
- Downstream integration: printed masters feed silicone mold replication, painting and assembly.
Resin Range and Application Fit
Each resin in our SLA range is selected against the function the part must perform, not only its color. The table below maps our standard materials to typical project use.
| Resin | Character | Typical Application |
|---|---|---|
| Yellow ABS-Like | Strength and toughness comparable to ABS | Functional housings, snap-fit parts, load-bearing prototypes |
| Off-White | General-purpose, high detail, smooth finish | Concept models, appearance prototypes, master patterns |
| Transparent | High light transmission after photocuring | Lenses, light guides, clear covers, fluid-visualization models |
| Black | Uniform matte black frosted appearance | High-contrast display parts, internal fixtures, dark enclosures |
| Flexible | Bendable, compressible rubber-like behavior | Seals, gaskets, grips, overmold simulation |
Where SLA Fits in the Product Development Chain
SLA is the first step in a sequence we run under one roof. A printed master can be finished and used as a silicone mold pattern, then replicated in urethane for small-batch trial production. Where a part needs machined accuracy or a metal insert, it routes to our CNC Milling Service instead.
Concept and Appearance Models
Smooth surfaces and fine detail for design reviews, ergonomic checks and client presentations.
Silicone Mold Masters
Printed patterns feed vacuum casting for low-cost, high-precision small-batch production.
Form, Fit and Function Checks
Rigid and flexible resins test assembly, sealing and handling before tooling investment.
Specifications That Drive a Quotation
We prepare each SLA proposal from the geometry and the working point of the part. The following variables determine process setup, orientation, support strategy and finishing route.
- Build envelope: maximum 1.7 × 0.8 × 0.65 m; larger assemblies are split and bonded.
- Layer thickness: selected against feature size and surface requirement.
- Wall thickness: minimum values depend on resin type and part orientation.
- Tolerance: confirmed against the drawing before production.
- Surface finish: as-built, sanded, polished or painted.
- Quantity: single prototype through small-batch replication.
Finishing, Assembly and Related Processes
Printed parts rarely ship as raw resin. We operate the finishing steps that turn a print into a presentation-ready or test-ready component, and we coordinate them in the same production flow.
- Painting & Coating for matte, glossy or textured color matching.
- Transparent Parts treatment for clear and semi-transparent components.
- Vacuum Casting for urethane copies from SLA or CNC masters.
- Grinding, polishing and sandblasting for surface refinement before inspection.
Quality Control and Confidentiality
We apply full-process inspection: incoming raw material checks, in-process sampling during production and final dimensional and appearance verification before shipment. Every customized workpiece is inspected against the agreed tolerance and appearance standard.
Customer drawings, models and product data are handled under project zoning in closed workshops, staff non-disclosure agreements and an isolated internal network that prevents unauthorized external transmission of files.
Information We Use to Configure Your Solution
To return an accurate SLA configuration and price, we work from the following project inputs. Missing items are confirmed with you before production begins.
| Input | Why We Need It |
|---|---|
| 3D model (STEP, STL or equivalent) | Geometry review, orientation and support planning |
| Part function and end use | Resin selection and wall-thickness guidance |
| Critical dimensions and tolerances | Inspection plan and acceptance criteria |
| Surface and color requirement | Finishing route and post-processing time |
| Quantity and delivery target | Build nesting, batch planning and packaging scope |

Frequently Asked Questions
What is the maximum size you can print in SLA resin?
Our SLA equipment covers a maximum build volume of 1.7 × 0.8 × 0.65 meters. Larger models are split into sections, printed and bonded, then finished so the joint is not visible on the final surface.
Which resin should I choose for a functional prototype?
Yellow ABS-like resin gives strength and toughness comparable to ABS and suits housings and snap-fit parts. Off-white resin is the general-purpose choice for detail and appearance. Flexible resin is used where the part must bend or compress.
Can you produce transparent SLA parts?
Yes. Transparent resin is a high-transmittance material in our SLA range. We also operate a dedicated transparent parts finishing process for clear and semi-transparent components.
Can SLA prints be used as silicone mold masters?
Yes. SLA masters are a standard input to our vacuum casting line, where silicone molds are used for low-cost, high-precision small-batch production in urethane materials.
How do you protect our design files?
Projects are separated in closed workshops, all staff sign non-disclosure agreements, and drawing files are held on an isolated internal network that blocks unauthorized external transmission.
What do you need to quote an SLA project?
Send the 3D model, the part function, critical dimensions and tolerances, surface and color requirements, quantity and delivery target. We review the geometry and return a configuration and price based on the working point of the part.
