FDM 3D Printing Filament Performance Map: Engineering Properties and Use Cases of PLA, ABS, PETG, and TPU
Selecting FDM filaments is an engineering tradeoff among service temperature, load type, assembly requirements, and post-processing needs. PLA delivers the best dimensional accuracy and easiest printing, but its heat resistance is limited. ABS offers better thermal resistance and impact toughness, though it requires tighter environmental control to prevent warping. PETG balances strength, toughness, and printability, making it a practical choice for most functional parts. TPU is the preferred option for flexible, wear-resistant, and shock-absorbing components. This guide compares the four materials from a practical engineering perspective and helps match material properties to prototypes, fixtures, and end-use parts more efficiently.

Metal 3D Printing Powder Management Standard: A Complete Workflow from Storage and Reclamation to Quality Control
This article outlines a complete powder management workflow for metal additive manufacturing, focusing on storage, recovery, sieving, traceability, and key quality metrics. In SLM/LPBF, powder condition directly affects spreadability, melt pool stability, porosity, density, and mechanical performance. The article explains practical controls for temperature, humidity, inert storage, recycling limits, contamination prevention, and batch-level tracking, and highlights how oxygen content, particle size distribution, flowability, and morphology determine consistent part quality in high-reliability production.

SLS Nylon Powder Material Performance Comparison: Engineering Application Selection of PA12, PA11, and Composite Nylon
This article compares the engineering performance of common SLS nylon powders from a practical selection perspective. It explains how PA12, PA11, and glass-/carbon-fiber reinforced nylons differ in strength, stiffness, elongation, impact resistance, heat resistance, moisture sensitivity, dimensional stability, processability, and total cost. Rather than choosing a material by strength alone, the right approach is to match the material to the operating conditions and failure mode. PA12 offers balanced performance and stable processing, PA11 is better for toughness, impact resistance, and low-temperature or fatigue-prone parts, while reinforced nylons are preferred for high stiffness, load-bearing structures, and tighter dimensional control.
