These properties impact the quality, performance, and suitability of finished parts for various industries—from automotive and aerospace to medical and mining.
1. Material Type and Grade
The substance used for 3D printing—be it polymers, metals, composites, or ceramics—directly affects product durability, heat resistance, flexibility, and strength. In B2B scenarios, buyers must specify not just the basic material (like ABS or stainless steel) but also the required grade or specific formulation to align with regulatory standards or operational demands (for example, food-grade plastics for packaging in the Middle East or high-tensile alloys for African mining equipment).
2. Dimensional Tolerance
Tolerance refers to the permissible deviation from specified dimensions. In B2B supply chains, particularly for automotive or aerospace components, even fractions of a millimeter can make the difference between a functioning assembly and a failed one. Clearly stating the acceptable tolerance (such as ±0.1mm) ensures interchangeability and compatibility with existing parts or international standards.
3. Surface Finish
Describes the texture or smoothness of the part’s surface, typically measured in microns (µm) of roughness. B2B buyers should clarify whether a matte, polished, or textured finish is necessary—for instance, a smooth finish for medical implants supplied to European clients or a rougher, “as-printed” finish for prototyping in South America to reduce costs.
4. Build Volume
Build volume specifies the maximum physical size that can be printed in a single operation by the printer (noted as XYZ dimensions in millimetres or inches). Understanding this figure is critical for international buyers who may need to split large components into smaller sections for transportation or assembly, especially when cross-border shipping is involved.
5. Layer Resolution
Specifies the height of each individual layer deposited during printing, usually in microns (µm). Finer resolutions (lower numbers) yield smoother and more detailed parts—critical for intricate prototypes for the UK architecture sector or precision tools for Saudi Arabian manufacturing.
6. Mechanical Properties (Strength, Hardness, Flexibility)
Mechanical benchmarks such as tensile strength, impact resistance, and elasticity should be matched to a part’s end application. For B2B buyers, ensuring that supplied parts comply with local or industry certifications (ISO, ASTM) is often non-negotiable, particularly for regulated sectors.
