Polypropylene - like PP
3D printing of polypropylene (PP) mainly uses FDM. The 3D model is sliced into layers by software, and PP filament is fed into a heated extruder (220–240°C). It’s melted and deposited layer-by-layer onto a heated build plate (80–100°C) to reduce warping. Supports may be added for overhangs. After printing, parts cool slowly; supports are removed, and post-processing (e.g., sanding) may follow. This yields flexible, chemical-resistant PP parts for automotive, packaging, and household uses.
Common 3D printable products:
- Automotive & Transportation：Parts like bumper prototypes
- Packaging & Consumer Goods：Custom containers, bottle caps
- Industrial & Corrosion-Resistant Equipment：Chemical tanks

How Does Nylon 3D Printing Work?
Nylon 3D printing typically uses powder bed fusion technologies like Selective Laser Sintering (SLS) or Multi-Jet Fusion (MJF). The process starts with spreading a thin layer of nylon powder (e.g., PA11, PA12) on a build platform. In SLS, a laser sinters the powder particles together at high temperature (just below melting point) according to the digital model, while MJF uses inkjet nozzles to apply fusing agents before heating. Each layer bonds with the previous one, gradually building the part via layer-by-layer accumulation. Supports are usually unnecessary due to the powder bed’s structural support. After printing, excess powder is recycled, and parts undergo cooling, depowdering, and post-processing (e.g., dyeing, vapor smoothing) for improved surface finish. This method enables complex, durable, and flexible nylon components for automotive, medical, and industrial applications.
