标题: Shenzhen Shenghua 3D Launches Meter-Scale PEP System for Refractory Metals and Advanced Ceramics
Nanjixiong introduction
SLM is a mainstream industrial process but presents difficulties for materials such as tungsten and silicon nitride. Shenzhen Shenghua 3D takes another approach: print metal or ceramic green bodies from pellets, then post-process them in a sintering furnace. At TCT Shenzhen, Nanjixiong saw new PEP equipment, tungsten alloy samples, silicon nitride nose cones and copper–ceramic functionally graded samples.

On October 14, 2026, Nanjixiong interviewed the company at the exhibition. Its proprietary Powder Extrusion Printing (PEP) is an indirect manufacturing route developed from FDM, combining printing and powder metallurgy. Powders and binders are compounded into pellets, screw extrusion prints green bodies, and debinding and sintering produce the final parts. No laser is required, helping lower equipment cost and accommodate a broad material range.

Meter-scale equipment expands the PEP range

The display featured the single-nozzle UPS-Lite and independent dual-nozzle UPS-LiteD for experimentation. Compact bodies fit limited laboratory space, with simplified operation and convenient material changes without extensive specialist training. They target material exploration and process validation in universities, institutes and corporate R&D.

Staff said the newly launched UPS-1000S provides a maximum build volume of 1000 × 1000 × 600 mm. Relatively few companies offer meter-scale indirect printing, making the format distinctive.

The launch expands opportunities for integrated large components, such as aeroengine structures, irregular nuclear-industry parts and new-energy equipment assemblies, beyond smaller build envelopes. Integrated forming reduces joining and finishing, assembly errors and performance-loss risks. It extends PEP from research specimens and small batches toward fabrication of major equipment components and broader industrial applications.

A broad material and application portfolio

PEP's central value is making difficult-to-process materials printable. The portfolio includes tungsten and its alloys, copper and its alloys, stainless steel, carbides, nitrides, oxides, superconducting and ultrahigh-temperature ceramics, and cermets such as cemented carbides. Binder systems can be matched to materials and applications.

For tungsten, the route offers complex, high-density geometries while avoiding conventional machining constraints. The company reports sintered tungsten alloy density up to 99.6%.

Silicon nitride and silicon carbide can form complex nose cones and satellite nozzles with heat resistance, thermal-shock performance and lightweight structures. Integrated copper–ceramic gradients offer new combinations for thermal management and electronic packaging.

Shenghua is developing a repeatable solution spanning metal, ceramic and cermet feedstocks; meter-scale printing; and complete debinding and sintering. For difficult systems such as tungsten alloys and silicon nitride, the significance is a broader-material, lower-equipment-barrier indirect manufacturing option.

Nanjixiong's observation
PEP differentiates through lower equipment costs and broad materials rather than competing directly with SLM on precision and speed. Refractory materials and specialty ceramics are challenging for laser routes. Meter-scale equipment indicates ambitions beyond laboratory tools toward large industrial components.
