3D printing technology's core competitiveness lies in the deep integration of material properties and processing parameters. The following systematically collates the technical parameters of mainstream 3D printing materials from three dimensions: material physical properties, processing parameters, and application indicators, providing data support for engineering applications.

• ABS is suitable for impact-resistant structural parts (e.g., drone housings). Control print bed temperature at 80-100℃ to reduce warping.

• PLA's biocompatibility makes it ideal for medical applications (e.g., surgical guides). Use a 0.4mm nozzle to achieve ±0.1mm precision.

• For general resin printing of jewelry models, layer thickness ≤50μm to achieve Ra0.2μm surface roughness.

• For elastic resin printing of silicone molds, control exposure time at 10-15 seconds to avoid toughness degradation due to over-crosslinking.

• Stainless steel printing for aircraft engine blades requires oxygen content ≤200ppm to prevent high-temperature oxidation.

• Titanium alloy printing for artificial joints uses electron beam melting (EBM) to achieve 99.5% density.

• For automotive wheel hub printing, use a twin-screw extruder, control wire feeding speed at 30-50mm/s, and match 1.75mm wire for structural lightweighting.

• Full ceramic crowns must comply with ISO 6872: lead/cadmium leaching ≤0.1ppm, flexural strength ≥800 MPa.

• Ceramic substrates must pass 85℃/85%RH humidity test with insulation resistance ≥10¹²Ω·cm.

• UAV wing printing requires fiber orientation ≥90% and interlaminar shear strength ≥50 MPa.

• Piston manufacturing must pass 500-hour high-temperature fatigue test (200-300℃) with mass loss ≤0.5%.

Note: Specific strength = tensile strength/density, a core indicator for lightweight performance.
