The Formnext + PM South China 3D Printing and Additive Manufacturing Exhibition (October 14–16, 2026, at the Shenzhen World Exhibition & Convention Center, Bao'an) has officially opened. The event showcases advanced 3D printing equipment, software, and end-to-end industrial manufacturing solutions tailored for high-growth sectors such as low-altitude economics, new energy vehicles (NEVs), medical engineering, and precision tooling.
Exhibiting at Hall 15, Booth J80, Qingdao Zhongxin Huamei Plastic Co., Ltd. is engaging with international buyers, equipment manufacturers, and R&D engineers to address critical polymer challenges in industrial additive manufacturing.
A primary highlight of the exhibition is Fused Granular Fabrication (FGF) pellet 3D printing. By feeding modified plastic granules directly into a screw extruder—bypassing filament production—FGF technology delivers dramatically higher deposition speeds, lower raw material costs, and seamless production for large-scale industrial components.
What Field Hazards Threaten Large-Format FGF Pellet 3D Printing?
Industrial print service providers and OEM manufacturers face severe material and thermal hurdles when producing large-scale tools, jigs, fixtures, foundry patterns, and equipment enclosures via FGF printing:
Thermal Stress and Part Warpage: Large-format print beds undergo differential cooling, creating high internal tensile stress that triggers corner lifting, bed detachment, and dimensional failure.
Layer Delamination under Load: Inconsistent melt flow or inadequate heat retention between extruded layers weakens z-axis mechanical adhesion, causing structural shearing under operational stress.
Severe Operational Service Environments: End-use components deployed in marine hardware, power grids, or mining equipment fail rapidly when exposed to ultraviolet (UV) radiation, severe thermal cycling, or chemical contact.
Processing Instability in Fiber-Filled Pellets: Fiber reinforced compounds with erratic viscosity cause screw slippage, pressure surges, and surface finish defects.
Technical Advantages of Tailored FGF 3D Printing Compounds
Engineered custom 3D printing polymers integrate optimized rheological modifiers, crystallization controllers, and anti-warpage packages designed specifically for direct screw extrusion and FGF pellet 3D printers:
Minimal Volumetric Shrinkage and Distortion: Suppresses internal cooling contraction across large surface areas, eliminating corner curling and warpage on multi-meter build platforms.
Enhanced Z-Axis Interlayer Thermal Fusion: Chemically modified polymer matrices promote inter-chain polymer diffusion across hot extrusion beads, producing isotropic mechanical strength.
Cost-Effective Large-Scale Manufacturing: Direct pellet feeding eliminates filament spooling costs while boosting hourly volumetric output for heavy structural components.
Functional Reinforcement Options: Offers glass fiber (GF), carbon fiber (CF), mineral-filled, weatherable, and flame-retardant modifications tailored to specific equipment requirements.
Consistent Batch-to-Batch Melt Viscosity: Precise compounding ensures steady screw torque, uniform extrusion output, and smooth surface finishes during continuous long-run print jobs.
