Custom 3D Printing Surface Finishes
Discover a range of surface finishes to enhance the appearance and functionality of your parts.
Name | Color | Application/Materials | Description |
---|---|---|---|
Polishing | N/a | Metals / Plastics | A surface treatment that results in a smooth, shiny finish, enhancing the appearance and reducing surface roughness. Typically used to improve aesthetic appeal or functionality in applications requiring minimal friction or increased surface clarity. |
Grinding | N/a | Metals / Plastics | A process that removes material from a surface using an abrasive tool, resulting in a smoother finish or precise dimensions. Commonly used for surface preparation, refinement, or achieving tight tolerances. |
Oil Spraying | N/a | Metals / Plastics | A coating process where oil is sprayed onto the surface to provide lubrication, prevent rust, and improve corrosion resistance. It creates a thin, protective layer on metal surfaces. |
Powder Coating | Available in various colors | Metals | A dry finishing process where powdered paint is applied to a surface and then cured under heat to form a durable, smooth, and protective layer. It enhances corrosion resistance and appearance. |

3D Printing Service FAQs
3D printing is a manufacturing process that builds objects layer by layer from a digital 3D model. It can use a wide range of materials, such as plastics, metals, and resins, to create everything from functional prototypes to complex production parts. The process works by either extruding material in thin layers or using technologies like lasers to solidify powdered or liquid materials. The method chosen depends on factors like the material, required finish, and part complexity.
3D printing offers several key benefits, including the ability to produce complex designs that traditional methods struggle to achieve. It enables faster prototyping, which speeds up product development. Since it doesn’t require expensive tooling, 3D printing is cost-effective for low-volume production. Additionally, it allows for greater flexibility, as designs can be easily modified without significant delays.
The time required for 3D printing depends on factors like part size, complexity, and the printing technology used. Smaller and simpler parts can often be produced in as little as one to three days, while larger or more detailed projects may take longer. If you provide your design file, we can give you a more accurate estimate based on your specific project requirements.
The cost of 3D printing varies based on the design, material, and chosen printing process. Post-production operations, such as finishing or manual work, often contribute significantly to the overall cost. For end-use parts, laser-based processes like SLS (Selective Laser Sintering) are typically an economical choice, especially when cost is a priority.
Choosing the best 3D printing technology depends on the specific requirements of your project. Consider factors such as material strength, heat resistance, water resistance, and surface finish. These criteria will help you determine whether plastic or metal 3D printing suits your application. If unsure, our team can guide you to the most appropriate technology for your needs.
While 3D printing is excellent for prototyping and small-batch production, it’s not typically the first choice for large-scale manufacturing. Traditional methods like injection molding are more cost-effective and efficient when producing high volumes. However, 3D printing is ideal for customized products or small, flexible runs. As this technology continues to advance, it may also play a bigger role in mass production.
For the best results, we recommend submitting design files in either STEP (.stp) or STL (.stl) formats. These formats ensure high accuracy and detailed prints. If your design is in a different format, converting it to one of these formats will help preserve its integrity during the printing process. Our team is available to assist with any questions regarding file formats or conversions.
