Jewelry 3D Printing Services 2025
From CAD to Carat — JLYPT’s Complete Process Guide

 

Introduction
Jewelry is no longer limited by the dexterity of a bench jeweler’s hand. With high-resolution stereolithography (SLA), direct metal laser sintering (DMLS), and precision wax-casting workflows, JLYPT turns digital dreams into wearable art in 48 hours. Our ISO 22196-certified lab produces 3,000+ jewelry patterns monthly—engagement rings, signet pendants, micro-pavé clasps—in 18 k gold, platinum, or bio-compatible resin. This guide delivers the material datasheets, design-for-casting rules, regulatory checklists, and three never-published case studies that saved designers 60 % in gold loss and 4 weeks of bench time.

Section 1 — Workflow Overview
1.1 Design → CAD → Print Pattern
• RhinoGold or MatrixGold → STL → 50 µm layers → burnout-ready pattern.
1.2 Investment Casting Pathway
• 3D-printed wax/resin → tree assembly → ceramic shell → 750 °C burnout → 1,050 °C pour → finish.
1.3 Direct Metal Pathway (DMLS)
• DMLS 18k powder → support removal → tumbling → rhodium plate → final polish.
Section 2 — Design for Jewelry (DfJ)
2.1 Wall Thickness Rules
• Wax patterns: min 0.4 mm for gold, 0.6 mm for platinum.
• DMLS: min 0.25 mm for 18k, 0.35 mm for Pt950.
2.2 Sprue & Gate Design
• Sprue diameter ≥ 2.5 × thickest section; gate angle 45° to reduce turbulence.
2.3 Micro-Setting Tolerances
• Stone seat diameter +0.05 mm oversize for pavé setting.
Section 3 — Material Deep-Dive
3.1 Castable Wax (Solidscape)
• Ash < 0.01 %, expansion < 0.2 % at 100 °C.
• Burnout ramp: 2 °C/min to 350 °C, hold 60 min.
3.2 Castable Resin (Next GP-Cast)
• Linear shrink 0.6 %, supports dissolve in 40 °C water.
3.3 DMLS 18k Gold
• Laser power 200 W, layer 30 µm, argon atmosphere 0.1 % O₂.
Section 4 — Regulatory & Hallmarking
Region Hallmark Laser Engrave Minimum Au % Notes
USA 18k Yes 75 FTC compliant
EU 750 Yes 75 CEN standard

Case 2 — Art-Deco Pendant
Client: Museum shop
Challenge: 200 pieces, sterling silver, 2-week turnaround.
Solution: MJP wax, tree-assembly, lost-wax batch cast.
Yield: 98 % usable parts, 30 % gold loss reduction.
Case 3 — Flexible Watch Strap
Client: Luxury brand
Challenge: TPU 95 A strap, integrated clasp, 500 pcs.
Solution: SLS TPU, dye-sublimation color, ultrasonic weld.
Fatigue: 20,000 bend cycles passed.
Section 7 — Cost & ROI
Method Wax/Resin ($) Casting ($) Finish ($) Total ($/g) Lead
SLA Wax 0.30 0.80 0.10 1.20 24 h
DMLS 18k 0.15 1.05 72 h
Hand-Carve 2.00 0.80 0.25 3.05 21 days
Section 8 — Sustainability
