Polishing commonly removes burrs and machining marks, resulting in smooth, uniform surfaces. Manual polishing preps surfaces for steps like painting or sandblasting.
High-polishing produces transparent PMMA (acrylic) components, commonly used in lightguides or lenses.
Vapor-polished PC parts, often functional test components, are widely used in prototyping.

Blasting is used to clean and deburr parts. It can serve as an independent process or a preparatory step for subsequent surface finishes, such as anodizing or painting. This process involves controlled spraying of abrasive media against the product surface.
At Marigold Rapid, we commonly use sandblasting, aquablasting, and bead blasting.

Painting is one of the most widely used surface treatments for industrial products and daily items. It enables various finishes, including matt, glossy, textured, and soft-touch coatings, with virtually unlimited color possibilities in theory. The process involves spraying a layer of paint onto the part's surface. Colors can be matched to the customer’s specified Pantone color number, while finishes range from matte, gloss to metallic. Painting also provides protective benefits, effectively safeguarding metal parts against oxidation and corrosion.

Anodizing is widely applied to aluminum, magnesium, or titanium electronic products. This process enhances corrosion resistance, increases surface hardness, improves wear resistance, and facilitates heat dissipation.
At Marigold Rapid, we frequently utilize Type II anodizing, which involves introducing tints or dyes to parts to achieve various colors. For components requiring a harder surface than standard anodizing, we also offer Type III anodizing—commonly referred to as "hard anodizing.

Powder coating is a process where a plastic finish in powder form is applied to metal, then baked to a fluid state to bond with the metal surface. This technique is primarily used for coating metal components in various industries, such as household appliances, drum hardware, and automotive, motorcycle, and bicycle parts.
At Marigold Rapid, the most popular powder coating colors are black, silver, white, blue, and red.

Brushing is a surface treatment process where abrasive belts are used to create directional traces on material surfaces, primarily for aesthetic purposes. This finish is achieved by mechanically polishing or abrading the metal's outer surface. Brushing can be applied globally or selectively, in single or multiple directions.
At Marigold Rapid, our brushing surface finish is predominantly offered for CNC-machined rapid prototyping parts and sheet metal prototypes

Passivation is a chemical treatment for stainless steel and other alloys that enhances the ability of the treated surfaces to resist corrosion. There are many benefits of passivated equipment and systems:
Passivation removes surface contamination.
Passivation increases corrosion resistance.

Laser marking is a highly cost-effective method to apply logos or custom lettering to designs, often used for custom part tagging. It can be easily applied to prototypes and scaled up for production.
At Marigold Rapid, laser marking can be applied to the mold or directly to final parts; this ensures crisp, consistent information on each part or serialization.

Electroplating is the process of using electrodeposition to coat an object with a layer of metal. Engineers utilize controlled electrolysis to transfer the desired metal coating from an anode (a metal-containing part serving as the plating source) to a cathode (the part to be plated).
At Marigold Rapid, electroplating is widely used across various industries to coat metal objects, adding desired properties not inherent in the original material—such as improved corrosion resistance.
