Stainless Steel Parts 3D Printing Service

Wall Thickness

Minimum wall thickness of 0.8 mm recommended to ensure sufficient strength and avoid deformation during printing.

Tolerance

Typical tolerances range from ±0.1 mm to ±0.3 mm depending on the printing process and part geometry.

Hole Design

Design holes with a minimum diameter of 1 mm; consider adding a slight oversize to account for potential shrinkage.

Support Structures

Essential for overhangs and complex geometries to prevent collapse during the build. Supports should be easy to remove to avoid damaging the part.

Orientation

Optimize part orientation to minimize support use and surface roughness while ensuring the best mechanical properties.

Thermal Management

Implement controlled cooling techniques to manage residual stresses and reduce warping or distortion of the part.

Lattice Structures

Use lattice structures to reduce weight and material usage without compromising the structural integrity of the part.

Stress Concentration

Design to minimize sharp corners and abrupt changes in cross-section which can concentrate stress and lead to failure.

Heat Treatment

Consider post-processing heat treatments to relieve internal stresses and enhance mechanical properties.

Material Selection

Choose the appropriate stainless steel alloy (e.g., 316L, 17-4 PH) based on the required corrosion resistance, strength, and application-specific properties.

Texture

Texture outcomes can vary significantly; adjust laser parameters and scan strategies to minimize surface roughness and achieve finer features.

Surface Roughness

Surface finish can be optimized through post-processing methods such as tumbling, electropolishing, or CNC machining to enhance aesthetic and functional qualities.

Precision Control

Implement tight process controls to ensure high precision, especially in complex geometries or components requiring tight tolerances.

Layer Control

Manage layer thickness and melting parameters carefully to avoid defects and ensure uniform microstructure throughout the part.

Shrinkage Control

Design parts with compensation for thermal shrinkage, using predictive software to model and adjust the part dimensions pre-printing.

Warp Control

Utilize optimal support structures and heat treatment strategies to minimize warping and ensure dimensional stability.

Post-processing

Common techniques include stress relieving heat treatments, surface finishing processes, and additional machining to meet specific industry standards.
