Typical Grades	Typical Dimensional Tolerance	Notes
ABS-like resin, transparent resin, high-temperature resin	±0.05 mm	Best for appearance prototypes, transparent parts, and detailed models.
PA12 nylon	±0.10 mm	Suitable for functional prototypes and low-volume nylon parts.
GF PA12 / glass-filled nylon powder	±0.15 mm	Higher stiffness; fiber-filled materials may have more dimensional variation.
Large resin or nylon prototype parts	±0.20-0.50 mm	Depends heavily on part size, orientation, support, and post-processing.
Aluminum alloy powders such as AlSi10Mg or project-specific aluminum powders	As printed: ±0.10 mm; post-machined: to CNC tolerances per ISO 2768-f upon request	Used for lightweight and complex metal parts; critical faces can be CNC finished.
316L, 17-4PH or project-specific stainless powders	As printed: ±0.10 mm; post-machined: to CNC tolerances per ISO 2768-f upon request	Suitable for complex, durable metal parts.
Ti-6Al-4V / TC4 and selected titanium powders	As printed: ±0.10 mm; post-machined: to CNC tolerances per ISO 2768-f upon request	Suitable for aerospace, medical, lightweight, and high-performance applications.

3D Printing Surface Finishes

Enhance printed parts with post-processing options that improve appearance, surface quality, and functional performance.

Clear Coating

Provides additional protection and enhances the appearance of printed components.

Dyeing

Adds uniform color to nylon printed parts without affecting part geometry.

Vapor Smoothing

Smooths selected plastic parts by reducing visible layer lines while improving surface quality.

Painting

Applies custom colors and finishes to improve appearance or match product requirements.

Sanding & Smoothing

Reduces layer lines and improves surface consistency for prototypes and presentation models.

Support Removal

Removes support structures and prepares printed parts for inspection, assembly, or additional finishing.

3D Printing Across Industries

Rapid 3D printing helps accelerate product development with fast design iterations, functional prototypes, and end-use parts for a wide range of industries.

3D Printing Tolerances & Standards

3D printed parts have different dimensional behavior than machined metal. Our standard tolerance for functional prototypes follows ISO 2768-c (Coarse) , which accounts for material shrinkage and layer-by-layer accumulation inherent to the printing process. On typical outer dimensions, our printers consistently hold tolerances within the Coarse grade limits. If tight fits or critical interfaces are required, mark those features clearly in your CAD file or 2D drawing. We will adjust orientation, scaling, and post-processing parameters accordingly. For metal 3D printed parts, critical faces can be CNC post-machined to tighter tolerances upon request.

Basic Size Range (mm)	Fine (ISO 2768-f)	Medium (ISO 2768-m)	Coarse (ISO 2768-c)	Very Coarse (ISO 2768-v)
0.5 up to 3	± 0.05mm	± 0.1mm	± 0.2mm	–
over 3 up to 6	± 0.05mm	± 0.1mm	± 0.3mm	± 0.5mm
over 6 up to 30	± 0.1mm	± 0.2mm	± 0.5mm	± 1mm
over 30 up to 120	± 0.15mm	± 0.3mm	± 0.8mm	± 1.5mm
over 120 up to 400	± 0.2mm	± 0.5mm	± 1.2mm	± 2.5mm
over 400 up to 1000	± 0.3mm	± 0.8mm	± 2mm	± 4mm
over 1000 up to 2000	± 0.5mm	± 1.2mm	± 3mm	± 6mm
over 2000 up to 4000	–	± 2mm	± 4mm	± 8mm
