Makelab's dimensional accuracy varies by technology and part geometry:

FDM (Fused Deposition Modeling)

• Typical tolerance: ±0.2mm to ±0.5mm for most dimensions
• Best case: ±0.1mm on simple, well-supported geometry
• Variables: Layer height, material shrinkage, part orientation, post-processing

SLA (Stereolithography)

• Typical tolerance: ±0.1mm to ±0.2mm for most dimensions
• Best case: ±0.05mm on small, detailed parts
• Variables: Resin type, part size, support placement

Industrial SLA

• Typical tolerance: ±0.1mm to ±0.3mm depending on size
• Best case: ±0.05mm on smaller sections of large parts
• Variables: Part size (larger parts may experience more deviation), geometry complexity

Factors Affecting Tolerance

• Material shrinkage during cooling or curing
• Part orientation during printing
• Support removal may affect surface finish on contact points
• Post-processing (sanding, coating) reduces precision
• Environmental conditions (humidity, temperature)
