Materials for CNC Metal Parts
Characteristics & Machining Performance
As-Printed / Raw Finish
The as-printed finish features a slightly rough or layered surface, typical of parts made directly from 3D printing without post-processing. Ideal for internal components, fit checks, or early-stage prototypes, this finish reflects the native texture and layer lines produced by FDM, SLA, SLS, or other additive manufacturing methods.
Sanding & Polishing
Sanding and polishing are manual or mechanical post-processing techniques that reduce visible layer lines and surface imperfections in 3D printed parts. Ideal for consumer products, display models, and presentation prototypes, this finish improves surface smoothness and enhances the overall appearance—perfect for painting or final use.
Bead Blasting / Media Tumbling
Bead blasting is a post-processing method used for SLS, MJF, and metal 3D printed parts. It removes powder residue and minor surface roughness, leaving a uniform matte or satin finish. Ideal for improving surface quality and preparing parts for coating or assembly.
Painting / Coating
Wet painting, airbrushing, or spray coating are common finishing methods used to enhance the color, texture, and appearance of 3D printed parts. Options include clear coatings for protection or textured paints for custom finishes—ideal for display models, enclosures, and end-use prototypes.
Dyeing (for Nylon parts like SLS/MJF)
Dyeing is a surface treatment used to add vibrant, long-lasting color to porous nylon parts produced by SLS or MJF printing. The dye penetrates the material, ensuring even coloration without affecting part dimensions—ideal for functional prototypes, enclosures, or cosmetic end-use parts.
Vapor Smoothing (FDM/FFF)
"Vapor smoothing is a chemical post-processing technique that melts and smooths the surface of FDM/FFF printed parts using controlled solvent vapors (like acetone for ABS). It produces a glossy, sealed finish with improved strength and an injection-molded look—ideal for consumer products and functional prototypes. "
Electroplating (for plastics or metals)
Electroplating enhances 3D printed metal or plastic parts by adding a thin metallic layer for improved surface hardness, conductivity, and a polished metal-like appearance. Plastic parts require a conductive primer before plating. Commonly used for prototypes, wear-resistant components, and decorative finishes.
Anodizing (for aluminum DMLS parts)
Anodizing is a surface treatment used on aluminum DMLS parts to enhance corrosion resistance, increase surface hardness, and add color. It creates a durable, non-conductive oxide layer ideal for functional or aesthetic applications. Suitable only for specific metal 3D printed materials like aluminum alloys.
Powder Coating (for metal parts)
Powder coating provides a tough, uniform, and protective finish for metal 3D printed components. Ideal for functional end-use parts, it enhances durability, impact resistance, and corrosion protection. This dry finishing process is widely used in industrial, automotive, and consumer-grade metal applications.
As-Cast / Mold Finish
This finish replicates the exact surface of the master model—whether matte, satin, or semi-gloss. It offers high detail accuracy and a smooth surface with minimal layer lines when using a polished master. Ideal for low-volume production and appearance prototypes that require clean, professional aesthetics without secondary finishing.
Glossy Finish
A glossy finish is achieved by using a highly polished master model and mold, resulting in a smooth, reflective surface with a near-injection-molded appearance. This finish is ideal for consumer product enclosures, display models, and presentation-ready prototypes that require a premium, high-shine look.
Textured / Matte Finish
A textured or matte finish is created using a sandblasted or matte-treated master model, resulting in a non-reflective surface that hides fingerprints and reduces glare. This finish is commonly used for prototypes, handheld devices, and functional parts requiring a clean, low-gloss appearance.
Custom Surface Coating
Custom coatings such as wet painting, soft-touch finishes, and metallic plating can be applied to vacuum cast parts to enhance appearance, texture, and user experience. Chrome-like or brushed metallic effects are ideal for presentation models and cosmetic prototypes where visual appeal matters.
Color Options
Vacuum cast parts can be tinted directly with pigmented polyurethane resins or painted after molding for specific color requirements. This allows for custom color-matching, transparent or opaque finishes, and visual consistency—ideal for prototypes, housings, and branding-sensitive applications.
Silk screen printing
Silk screen printing adds custom logos, text, and symbols onto vacuum cast parts with precise, durable ink application. Ideal for branding, labeling, or functional markings, this process works well on painted, textured, or smooth surfaces. It's commonly used for control panels, enclosures, and consumer product prototypes that require sharp visual detail.
