FCD PLUS 302：Large-Format 16K 3D Printer for Jewelry Production
The IFUN FCD PLUS 302 is a 16K MSLA 3D printer engineered for high-volume jewelry investment casting, featuring a 302×162×200 mm build platform that yields 204 or 540 rings per batch. Its C5-grade ground ball screw and 0.98 collimated optical engine eliminate Z-axis step lines and ensure uniform dimensional accuracy, cutting post-cast polishing labor by 50%. Equipped with 1 kg automatic resin refilling and a lower-unit 200 W UV chamber for convenient manual post-curing, it streamlines production from printing to burnout.
Engineered for Industrial Repeatability
Overcoming the limitations of traditional resin 3D printing with precision optical hardware and robust closed-loop motion systems.
High-Precision Z-Axis Transmission System
Engineered with a C5 ground lead screw, P5-bearing dual-rail quad-sliders, and a 57 closed-loop servo motor, this system delivers 0.002mm reciprocating precision and +300% vertical load stability. It eliminates horizontal layer lines and stepped patterns on tall, intricate models—such as 100mm statues and detailed jewelry masters—reducing post-processing labor hours by up to 50%.
Collimated Optical Engine for Dimensional Accuracy
Featuring an optical system with a <0.98 light divergence angle andfactory-certified 90% ~ 92% intensity uniformity, this light engine minimizes edge pixeldistortion across the entire platform. Designed for full-plate production of tight-tolerancecomponents and filigree jewelry, it prevents light bleed to ensure predictable assembly fitand batch-to-batch consistency.
Built-In 360° Integrated Post-Curing Chamber
Equipped with a 200W UV matrix light source and an embedded smart rotating platform, this integrated chamber provides uniform 360° material hardening following post-print washing. It streamlines secondary processing for complex hollow geometries while saving valuable desk space by eliminating standalone post-curing hardware.
Continuous Material Supply & Thermal Control
Engineered to guarantee uninterrupted execution for large-scale and tall print jobs, this system integrates a 2,000 ml automatic resin feeder with H0.5 mm liquid level sensingalongside a 200W rapid chamber heater (raising ambient temperature from 20°C to 35°Cin 8 minutes). By dynamically maintaining optimal vat levels during extended runs, iteliminates catastrophic print failures caused by mid-print resin exhaustion while ensuring stable viscosity across changing workshop environments.

Engineering Notes & Technical Interpretation
In-depth hardware and optical breakdown of how the IFUN FCD PLUS 302 maximizes accuracy, capacity, and yield in jewelry lost-wax casting.
Why does a C5 ground ball screw and closed-loop servo motor matter for jewelry manufacturing?
In lost-wax casting, visible layer lines (stepped patterns) on printed models transfer directly into the final metal casting, requiring intensive manual filing and polishing. The combination of a C5 industrial ground ball screw, P5 linear bearings, and a 57 closed-loop servo motor achieves 土0.002 mm reciprocating precision. This eliminates horizontal Z-banding, producing ultra-smooth surfaces that cut manual polishing labor hours by up to 50%.
How does <0.98° optical collimation impact multi-part jewelry assembly?
Uncollimated light sources scatter light across large build plates, causing edge distortion and dimensional variations between center and edge prints. The printer’s optical system features a <0.98° divergence angle and factory-calibrated 92% light uniformity, ensuring parallel rays hit every square millimeter identically. By eliminating edge light bleed, it maintains strict dimensional accuracy across the entire build plate so that rings, clasps, and multi-part jewelry fit together seamlessly.
Why is an integrated post-curing chamber superior to standalone curing units?
Traditional setups require dedicated table space for separate washing and curing stations, adding clutter and handling steps for delicate prints. By embedding a 200W UV matrix with a 360° smart rotating platform directly inside the printer base, parts can undergo uniform secondary curing immediately after washing without needing additional standalone curing equipment. This streamlines post-processing while saving valuable workshop floor space.
What is the production value of the automatic feeding system?
Large-volume or tall jewelry master prints consume substantial resin over multi-hour cycles. Running out of material mid-print causes catastrophic layer separation and job failure. The 土0.5 mm high-precision liquid level sensor and automatic feeding mechanism dynamically maintain a continuous 2,000 ml reservoir, enabling secure, unmonitored overnight printing for long-duration jobs without risk of resin exhaustion.
