Junjing’s Ceramic Photocuring: Metal Can Be Printed Too

September 23, 2026 News 9607

At Formnext Shenzhen 2026, Junjing Technology rounded out its photocuring ceramics lineup and added metal systems. General Manager Jiang Damei said the company provides a complete solution covering materials, equipment, and firing.

Ceramics now cover the full range: oxides such as alumina, zirconia, silicon carbide, and silica; nitrides such as silicon nitride and aluminum nitride; bioceramics such as hydroxyapatite and tricalcium phosphate; and functional ceramics such as ferrite and piezoelectric ceramics. On the metal side, photocurable copper, titanium alloy, and silver have all been successfully developed, and gold can also be printed. Copper parts are being sampled for liquid-cooling customers, while silver parts are displayed to compare green bodies with fired parts.

Applications focus on 3C semiconductors, biomedical, and industrial filtration. On-site samples include watch cases, implants, magnesia-stabilized zirconia filter parts, and silicon carbide filtration and heat-insulation parts. Biomedical is gradually scaling up.

Equipment spans from research-grade to industrial-grade. The research-grade line is a bestseller, with high precision and low material waste. It uses a peristaltic pump and dual-tank feeding, and handles slurries from low to high viscosity. Three models are available: 96×54 mm at 50 μm, 67.2×37.8 mm at 35 μm, and 20.7×11.6×100 mm at 10.8 μm; ceramic parts can achieve 60 μm microholes. Industrial-grade options include DLP and SLA. DLP build sizes include 384×216 mm and 288×162 mm, while SLA offers 100, 200, and 300 mm formats. Customers include Chinese universities and industrial companies, with exports to South Korea, Japan, the United States, and Brazil.

The photocuring “ceramics + metals” closed loop stands out for high precision and good surface quality, making it suitable for implants, electronic ceramics, and precision parts. Metals follow an indirect route of slurry forming, debinding, and firing, differentiating it from laser powder bed fusion. For small-batch, complex metal parts, it offers more room on cost and precision—for example, copper liquid-cooling components, silver jewelry, and titanium implants.
