Post Processing

No worries till the end.

About Post Processing

When it comes to manufacturing, the finishing touches can make all the difference. The final appearance and physical characteristics of the component produced by 3D printing will be determined by procedures including cleaning, curing, polishing, and coloring. In CNC machining, applying surface treatments like anodizing, powder coating, and electroless nickel plating will affect a product’s strength and electrical conductivity as well as its aesthetic.

Surface Finishes

At VMetal, adding a finish is a significant decision. In order to guarantee consistency and quality throughout batch production, we spend time researching and developing each of our post processing solutions. To make exceptional additive parts, we have carefully selected our post-production finishes to go with our product.

Here are some of the surface finishes we offer, for the ones you cannot find below, please contact us for special requests.

Electroplating

By using a direct electric current to reduce the cations of a metal, the process of electroplating creates a metal coating on a solid substrate. This method can be utilized for ornamental as well as corrosion and wear resistance applications.

✔ Aesthetic improvement
✔ Temperature resistance
✔ Increase corrosion resistance

Painting

Painting referring multiple method such as Wet paint, Spray painting, Powder coating and Silk screening which adds color on metal or plastic. Additionally, it strengthens the defenses against corrosion and other environmental deterioration for metal surfaces.

✔ Aesthetic improvement
✔ Increase corrosion resistance
✔ Increase abrasion resistance

Anodizing

With anodizing, the natural oxide coating on the surface of metal objects can be made thicker. In comparison to bare or untreated metal, it enhances corrosion and wear resistance and offers better paint priming and glue adherence.

✔ Aesthetic improvement
✔ Increase corrosion resistance
✔ Increase wear resistance

Sandblasting

Sandblasting makes use of the abrasive attributes of sand to produce surfaces that are smoother and have fewer physical flaws. The texture of the surface becomes smoother and uniform when the sand particles impact it. The profile the abrasive particles provide helps the primer adhere to the metal.

✔ Smoother
✔ Reduce flaws
✔ Remove old paint

Polishing

With rubbing or chemically treating a surface to make it shiny and smooth, providing a spotless finish with a specular reflection. An unpolished surface typically appears like a series of mountains and valleys when magnified thousands of times. To effectively flatten surface flaws, the abrasive polishing process starts with coarse grain sizes and subsequently moves to finer ones.

✔ Aesthetic improvement
✔ Increase corrosion resistance
✔ Increase chemical resistance

Brushing

Deburring and removing surface defects can be done with brushing. The surface pattern produced by the brush moving in one direction against the workpiece is a consistent parallel grain. On sides that are not parallel to the brushing direction, brushed sections will have edges that are slightly rounded. To achieve various process outputs, we employ various brushes and pastes.

✔ Deburring
✔ Edge rounding
✔ Smoother

Other Post Processing

Heat Treatment

Heat treatment includes heating a metal or alloy to a specified temperature but then cooling it to harden the material. This process enables a metal piece to be enhanced so that the material will be better able to endure wear and tear.
A few major sectors where heat treatment is significant include aerospace, automotive, hardware like saws and axes, computers, spaceflight, defense, and the oil and gas sector.

✔ Increase wear resistance
✔ Used in wide range industries production

Part Marking

Including Laser Engraving or Laser Etching and Laser Marking, part marking is the process of permanent labeling of components with product information, such as barcodes, model number, part numbers, and date codes. This would be done to enable the tracking of parts during their full life cycle.

✔ Mark metal parts
✔ Multiple marking method

Tapping

To create internal threads for a cap screw or bolt to be threaded into the hole of a part, the internal threads are produced by the machining process of tapping. A tap is a cylindrical or conical thread-cutting instrument with threads of a specified shape on the perimeter.

✔ Quickest way to produce internal threads

Welding

When two or more pieces are fused together during manufacturing, the join is formed as the parts cool under the action of heat, pressure, or both. Welding is most common used on metals and thermoplastics.

✔ Connecting metal parts with high strength
