Why Post-Processing Is Crucial
A 3D print straight from the machine is only the beginning. Professional post-processing determines whether your part is suitable for real-world application or remains stuck in the prototype phase.
Before vs After Post-Processing
A raw 3D print shows visible layer lines, support marks, a rough surface, inconsistent colour and weak connections. After post-processing, you get a smooth surface, professional finish, consistent colour, increased strength and a production-ready part.
Impact of post-processing: up to 85% improvement in surface quality, up to 40% strength increase possible and 95% acceptance by end users.
Essential Post-Processing Techniques
Support Removal
The first step in any post-processing process. Careful removal of support structures without damaging the final product.
- Manual removal: for complex geometries and fine details
- Chemical dissolution: PVA and HIPS supports in FDM printing
- Thermal treatment: for certain breakaway materials
Surface Smoothing
Transform rough 3D prints into smooth, professional surfaces with various smoothing techniques.
- Vapor smoothing: acetone for ABS, MEK for ASA
- Sanding & polishing: gradual grit increase 240-3000 grit
- Primer & filler: epoxy coating for a perfect finish
Colouring & Finishing
Give your part the desired colour and finish for professional presentation or end-use applications.
- Spray painting: automotive grade paints for durability
- Dyeing: dye for nylon and other materials
- Metallisation: electroplating for a metal look
Reinforcement
Increase the mechanical properties of your 3D print for functional applications and long-term use.
- Annealing: heat treatment for PLA and PETG
- Infiltration: epoxy infiltration for increased strength
- Densification: mechanical densification for higher density
Technology-Specific Post-Processing
Each 3D printing technology requires a specific post-processing approach.
SLA Processing
- Washing: IPA baths for resin removal
- UV curing: post-curing for maximum strength
- Sanding: fine sanding for a smooth surface
SLS/MJF Processing
- Depowdering: removing excess powder
- Bead blasting: surface levelling
- Dyeing: dye for the desired colour
FDM Processing
- Support removal: careful support removal
- Layer smoothing: vapor smoothing or sanding
- Painting: primer and paint for finishing
Quality Control & Inspection
Rigorous control for consistent, high-quality results. The inspection process runs in four steps: visual inspection (surface quality, colour consistency), dimensional control (accuracy and tolerances), mechanical test (strength and durability) and documentation (quality report and certification).
Quality Standards
- ISO 9001 certified: standardised quality processes
- Tolerances ±0.1mm: industrial precision guarantee
- Traceability: complete batch documentation
- 100% inspection: every part individually checked
