SLA 3D Printing Service & Rapid Prototyping in Taiwan

SLA 3D printing turns a CAD file into a physical, design-validation prototype in 1–3 days — the fastest, lowest-cost way to check form, fit, and appearance before you commit to tooling or machining.

JIERCHEN Enterprise Co., Ltd. (詰晟模型), Banqiao, New Taipei, has supplied prototypes to 1,000+ clients across 10+ countries since 1985. SLA is the first station on our four-stage prototyping line — Validate (SLA) → Test (CNC) → Pilot (casting) → Scale (injection molding) — so a 3D printed prototype you approve here can move straight into CNC machining or casting with the same engineering team, no vendor handoff.

Where SLA Fits

SLA Is the Validate Stage of Our Four-Process Line

Every project we run moves through the same four stages, and SLA 3D printing is deliberately the first one — it exists to catch design problems while they’re still cheap to fix.

Validate · SLA (1–3 days)
→
Test · CNC (3–7 days)
→
Pilot · Casting (5–10 days)
→
Scale · Injection Molding (4–8 weeks)

A 3D printed prototype from this stage answers three questions before you spend on machining: does the geometry actually fit together, does the part look right in your hand, and is anything about the design going to change after the first review. Because SLA needs no tooling and no fixturing, that answer costs a fraction of a CNC run and arrives in 1–3 days instead of 3–7.

Process Specs

SLA 3D Printing Capabilities

SpecDetail
ProcessStereolithography (SLA) — UV laser cures liquid photopolymer resin layer by layer directly from your CAD file
Typical lead time1–3 business days from an approved STEP/IGS/STL file
Best forForm/fit checks, cosmetic review, presentation models, complex hollow or lattice geometry a cutting tool can’t reach
Not ideal forTight tolerance, load-bearing, or production-material parts — move to CNC machining for those
File formats acceptedSTEP, IGS, STL (native CAD files such as SolidWorks/SLDPRT also accepted — ask if unsure)
Minimum orderNone — single concept models and small batches both run on the same line
Post-processing availableSanding, priming, spray painting, and other surface finishing to match a near-production appearance
ConfidentialityNDA available on request before you send a file

When to Move from 3D Printing to CNC Machining

SLA and CNC are complementary, not competing — we tell clients which one their part actually needs rather than defaulting to whichever we happen to be running that week.

Tolerance & critical dimensions

If a mating dimension has to hold to spec, move to CNC. We machine to ISO 2768-f general tolerance and verify critical features to ±0.01mm on CMM equipment — SLA tolerance varies with geometry and printer, and we won’t dress that up.

Production-representative material

SLA resin doesn’t behave like ABS, PC, aluminum, or the other engineering materials your final part will use. If you’re testing mechanical performance, a CNC prototype in the real material gives you a true read.

Specific surface finish

Anodizing, plating, and several other finishes only apply to machined metal or the right plastic substrate. See Surface Finishing for which options need a CNC part underneath them.

FAQ

SLA 3D Printing Questions, Answered

How fast is your SLA 3D printing service?
Typically 1–3 business days from an approved CAD file, depending on part size and quantity — the fastest option in our four-stage line, ahead of CNC (3–7 days), casting (5–10 days), and injection molding (4–8 weeks).
What tolerance can I expect from a 3D printed prototype?
SLA is built for visual and fit checks, and tolerance varies with part geometry and size. If a dimension is critical, tell us up front and we’ll recommend CNC machining instead, which we hold to ISO 2768-f and verify to ±0.01mm on CMM equipment.
Is there a minimum order quantity for rapid prototyping?
No. We print single concept models as readily as small batches, and pricing scales with part size and complexity rather than a fixed MOQ.
Can you post-process or paint an SLA prototype?
Yes — sanding, priming, and spray painting are available to bring an SLA part closer to a production-representative appearance. See Surface Finishing for the full list of finishes and which ones apply to printed versus machined parts.
Will my design file stay confidential?
Yes. We sign NDAs on request before you send a CAD file, and we’ve supported client confidentiality for prototype programs across the US, Europe, and Asia since 1985.
Can JIERCHEN 3D print medical device prototypes?
Yes, for cosmetic display models, engineering test prototypes, and non-contact applications such as medical device enclosures, jigs, and ergonomic form studies — standard SLA resin works well. For parts that will contact skin or the body, or for production medical use, you’ll need to specify a medical-grade material with the required biocompatibility certification and regulatory approval. Our standard SLA resin isn’t biocompatibility-certified and isn’t used for body-contact or implantable parts.
