Our 3D Printing Post-Processing Services
1. Support Removal & Cleaning
We carefully remove support structures, residual powder, uncured resin, and other printing residues from 3D printed parts. Proper cleaning prepares components for subsequent finishing processes and helps ensure consistent surface quality.
Key Benefits:
●Removes unwanted support structures and printing residues.
●Prepares parts for additional surface finishing.
●Helps maintain clean and consistent part surfaces.
Typical Applications: FDM, SLA, DLP, SLS, MJF, and metal 3D printed parts.
2. Sanding & Surface Smoothing
Our sanding and grinding processes reduce visible layer lines, remove minor surface imperfections, and improve overall surface smoothness. Different abrasive grades and finishing techniques are selected according to the material and desired surface quality.
Key Benefits:
●Improves surface smoothness and visual appearance.
●Reduces visible layer lines and manufacturing marks.
●Creates a suitable surface for painting and coating.
Typical Applications: 3D printed prototypes, product appearance models, plastic housings, and selected metal components.
3. Sandblasting & Bead Blasting
Sandblasting and bead blasting use controlled abrasive media to clean and refine part surfaces. These processes help remove residual powder, reduce minor surface irregularities, and create a consistent matte or satin texture.
Key Benefits:
●Creates uniform matte or satin surface finishes.
●Removes certain surface residues and contaminants.
●Helps prepare compatible surfaces for further coating.
Typical Applications: SLS and MJF printed parts, CNC-machined aluminum components, stainless steel parts, and metal prototypes.
4. Spray Painting & Coloring
We provide customized spray painting and coloring services to enhance the appearance and protection of manufactured parts. Available finishing options include custom colors, matte and gloss finishes, primers, and protective clear coatings.
Key Benefits:
●Offers flexible color and appearance options.
●Creates matte, satin, or glossy surface finishes.
●Helps conceal minor surface imperfections with proper preparation.
●Supports product branding and aesthetic requirements.
Typical Applications: 3D printed prototypes, vacuum-cast parts, product housings, and cosmetic models.
5. Polishing & Surface Finishing
Mechanical and manual polishing improve surface smoothness, clarity, and visual quality. Depending on the material, geometry, and finishing requirements, we select suitable polishing methods to achieve a refined surface appearance.
Key Benefits:
●Improves surface smoothness and overall appearance.
●Reduces minor scratches and surface irregularities.
●Helps achieve a refined finish for presentation and functional parts.
Typical Applications: SLA and DLP resin models, plastic components, metal parts, product prototypes, and cosmetic housings.
6. Vapor Smoothing
Vapor smoothing uses controlled chemical vapor to soften the outer surface of compatible thermoplastic materials. This process reduces visible layer lines and creates a smoother, more uniform finish. For certain materials, it can also improve surface sealing characteristics.
Key Benefits:
●Reduces visible layer lines and surface roughness.
●Creates smoother and more uniform surfaces.
●May improve surface sealing for compatible materials.
●Enhances the appearance of functional plastic components.
Typical Applications: Selected SLS, MJF, and FDM thermoplastic parts, depending on material compatibility.
7. Silk-Screen Printing
Silk-screen printing transfers customized graphics, logos, text, and patterns onto compatible part surfaces using a screen-printing process. It is suitable for adding branding and visual details to product components.
Key Benefits:
●Supports custom logos, text, symbols, and graphics.
●Provides consistent printing results for production batches.
●Offers a practical solution for product branding and identification.
●Supports a range of compatible colors and surface designs.
Typical Applications: Product housings, control panels, enclosures, promotional prototypes, and branded components.
8. Laser Engraving
Laser engraving uses a focused laser beam to mark or engrave text, logos, serial numbers, and other details onto compatible materials. It provides precise, durable markings without requiring traditional printing tools.
Key Benefits:
●Produces precise text, logos, and graphic details.
●Supports serial numbers, product codes, and identification marks.
●Provides permanent markings on compatible materials.
●Enables customized designs and branding.
Typical Applications: Metal components, plastic housings, product prototypes, nameplates, and industrial parts.
9. CNC Machining & Precision Finishing
For parts requiring tighter dimensional tolerances or accurate mating features, CNC machining provides additional precision after 3D printing. Milling, drilling, tapping, and other machining operations can be used to finish critical surfaces, holes, threads, and assembly interfaces.
Key Benefits:
●Improves dimensional accuracy on selected features.
●Achieves precise holes, threads, slots, and mating surfaces.
●Helps meet specific assembly and tolerance requirements.
●Combines the design flexibility of 3D printing with the precision of CNC machining.
Typical Applications: Functional prototypes, metal 3D printed components, precision housings, and parts requiring accurate mechanical interfaces.
10. Assembly & Insert Installation
We provide additional assembly services to transform individual manufactured components into functional products. Options include threaded insert installation, fastening, adhesive bonding, and component integration.
Key Benefits:
●Supports threaded inserts and mechanical fastening.
●Enables bonding and integration of multiple components.
●Improves assembly readiness and product functionality.
●Reduces the need for multiple manufacturing suppliers.
Typical Applications: Functional prototypes, product enclosures, mechanical assemblies, and low-volume production parts.
11. Dimensional Inspection & Quality Control
We use appropriate inspection equipment, including calipers, micrometers, coordinate measuring machines (CMMs), and 3D scanners, to evaluate part dimensions, geometric tolerances, and overall quality.
Key Benefits:
●Verifies critical dimensions and geometric requirements.
●Helps identify manufacturing deviations.
●Supports consistent product quality.
●Provides confidence in part fit, function, and assembly.
Typical Applications: Precision prototypes, functional components, CNC-machined parts, metal 3D printed parts, and production batches.
