3D Plus™ Tumbling

FAQs

Check out the frequently asked questions of tumbling.

• What is tumbling in post-processing?-
  Tumbling is a post-processing technique used to smooth and polish the surfaces of 3D printed or machined metal parts. This process involves placing the parts in a barrel with abrasive media, which rotates and tumbles the parts, removing roughness and imperfections for a polished finish.
• What types of materials can be tumbled?+
  Tumbling is commonly used for metal parts, including those made from stainless steel, aluminum, and titanium. It can also be applied to certain plastics and ceramics, but the type of abrasive media and the tumbling process may vary depending on the material.
• How long does the tumbling process take?+
  The duration of the tumbling process can vary depending on the material, size, and complexity of the parts, as well as the desired finish. It can range from a few hours to several days. Periodic inspections during the process ensure that the parts achieve the required smoothness and polish without over-processing.
• What are the benefits of tumbling for 3D printed parts?+
  Tumbling improves the surface finish of 3D printed parts by removing roughness and burrs, resulting in a polished, professional appearance. It also enhances the parts' aesthetic appeal, prepares them for further processing like painting or coating, and increases their durability.
• Are there any limitations to the tumbling process?+
  Tumbling is less effective for parts with intricate details or delicate features, as the abrasive action can damage fine structures. Additionally, it may not be suitable for parts made from very soft or brittle materials. Careful selection of abrasive media and process parameters is essential to achieve the desired results without compromising the integrity of the parts.
