High-Resolution SLA 3D Printing for Smooth Prototypes
Stereolithography (SLA) is the gold standard in additive manufacturing for producing parts with exceptional surface smoothness and intricate detail. Unlike powder-based methods (SLS) or filament extrusion (FDM), SLA utilizes a precision UV laser to cure liquid photopolymer resin layer by layer. This results in isotropic, watertight parts with a finish comparable to injection molding.
At JUCHENG, we operate a fleet of large-format industrial SLA machines. We specialize in transforming digital designs into high-fidelity physical models. Whether you need a crystal-clear automotive lens, a highly detailed figurine, or a master pattern for vacuum casting, our SLA service delivers the aesthetic perfection and dimensional accuracy required for concept verification and marketing showcases.

JUCHENG’s Industrial SLA Capabilities

We focus on delivering aesthetic perfection through advanced machinery and skilled post-processing:
  • Large Build Capacity: Our machines feature massive build platforms (up to 800mm x 600mm), allowing for the production of large single-piece automotive dashboards or appliance housings without gluing.
  • Ultra-Fine Resolution: We can print with layer thicknesses as low as 0.05mm, capturing fine textures, text, and sharp edges that other methods miss.
  • Optical Clarity: We have specialized protocols for printing and finishing clear resins to achieve glass-like transparency (transmittance > 90%).
  • Post-Processing Mastery: SLA parts require support removal and sanding. Our finishing team expertly sands away support marks, polishes surfaces, and applies UV clear coats or paints to achieve a Class-A finish.

Materials Available

SLA Resin Options
We stock a diverse library of functional resins to simulate engineering plastics:
Material Class Key Characteristics Best Application
Standard White/Grey Smooth surface, easy to paint, ABS-like properties. Visual models, concept verification.
Clear Resin High optical clarity, simulates PMMA/PC. Lenses, light guides, fluid visualization.
Tough Resin Durable and impact resistant, simulates PP/ABS. Snap-fits, handheld devices, functional assemblies.
High-Temp Resin Heat deflection up to 260°C (ceramic filled). Under-hood testing, airflow components, molds.
Castable Resin Burns out cleanly with no ash. Investment casting patterns for jewelry/dental.

Why Choose Us

The JUCHENG SLA Advantage
  • Finishing is Key: Raw SLA parts have support structures. We don't just ship raw parts; we carefully remove supports, wet-sand the surface, and bead blast or paint them to your specifications.
  • Material Quality: We use premium resins from top suppliers (like Somos®), ensuring your parts don't warp or yellow immediately.
  • Capacity: With multiple large-frame machines running 24/7, we can deliver large parts or batches of small parts in as fast as 24-48 hours.
  • Design Checks: We review your files for wall thickness issues and support placement to minimize scarring on critical A-surfaces.

Advantages

Key Benefits of SLA Technology
  • Aesthetics: The best technology for cosmetic prototypes. Layer lines are virtually invisible on vertical walls.
  • Precision: Capable of holding tight tolerances on small features (+/- 0.1mm).
  • Watertight: Cured resin is solid and non-porous, making it suitable for fluid handling prototypes.
  • Speed: Laser curing is fast, allowing for rapid iteration of design concepts overnight.

Industries Served

Industries Relying on SLA Models
  • Automotive: Headlight and taillight prototyping (Clear), interior knobs, air vents.
  • Consumer Electronics: Smartphone mockups, wearable device casings, earbud prototypes.
  • Medical: Anatomical models for surgical planning (clear/colored), microfluidic chips.
  • Art & Entertainment: Movie props, character design verification, architectural scale models.
  • Casting: Master patterns for vacuum casting and investment casting.
