Surface Finishing

Surface finishing involves enhancing the surface quality of parts, making them smoother and more aesthetically pleasing. This process can significantly improve the tactile and visual appeal of your products.

  • Sanding: Sanding involves manually or automatically abrading the surface to remove rough spots, layer lines, and minor imperfections. This technique can be tailored to achieve various levels of smoothness, from coarse to fine finishes.
  • Bead Blasting: Bead blasting uses fine beads propelled at high speed to clean and polish the surface of a part. This method is excellent for creating a uniform matte finish and can remove surface contaminants without damaging the part.
  • Tumbling: Tumbling involves placing parts in a barrel with abrasive media that vibrates or rotates. This process smooths and polishes the surfaces, making it ideal for bulk finishing small to medium-sized parts efficiently.

SLA Finishing Grades

Formero offers various SLA (Stereolithography) finishing grades to meet your specific project requirements. Our finishing options ensure that your parts achieve the desired level of smoothness and clarity.

  • Standard Finish: Supports are removed, affected surfaces are lightly sanded with 180-240 grit sandpaper and bead blasted to produce an even finish.
  • Engineering Finish: Supports are removed along with external layer lines. Affected surfaces are sanded down using 400 grit sandpaper and bead blasted.
  • Premium Finish: Supports are removed along with internal and external layer lines. Affected surfaces are sanded down using 400 grit sandpaper and bead blasted.

Painting, Dyeing & Coating

Painting and coating add colour, protection, and additional properties to your parts. This process not only improves the appearance but also enhances durability and resistance to environmental factors.

  • Spray Painting: Spray painting involves applying paint through a fine spray, achieving an even coat over the entire surface. It is versatile and can be used for various colours and finishes, from glossy to matte. We are able to match any Pantone colour.
  • Dyeing: Dyeing imparts colour to your parts by immersing them in a dye solution, providing uniform coloration throughout the material. We offer a variety of colours depending on part substrate. For MJF (Multi Jet Fusion) parts, we provide black dyeing as a standard service at no additional cost.
  • Z-Bonding: Z-Bonding involves applying a bonding agent to CJP printed parts to improve their structural integrity and surface finish. This technique enhances the strength and durability of the printed parts. On request we can also apply this to SLS and MJF printed parts to improve water tightness and waterproofing at an additional cost.
  • Clear Lacquer: Clear lacquer coating provides a glossy finish, improved transparency on clear SLA parts and additional protection to the surface. This coating enhances the aesthetic appeal and longevity of the parts by protecting against scratches and environmental factors.


Formero offers various texture options to enhance the aesthetic appeal and functionality of your 3D printed parts. Whether you require a subtle texture for improved grip or a more pronounced texture for added visual interest, we can customise the surface finish to meet your specific design requirements.

Threads & Inserts

Formero offers direct tapping and threading for your printed parts, as well as the installation of inserts for large production runs. We accommodate most standard metric and imperial thread types, as well as commonly used heat set, press-fit, and tapping inserts.

Assembly and Testing

Assembly and testing ensure that your parts are not only individually perfected but also work seamlessly as part of a larger system. This service helps ensure functionality and reliability of complex assemblies.

  • Manual Assembly: Our skilled technicians are able to assemble parts by hand, ensuring precise and careful assembly of components. This method allows for flexibility and detailed attention to complex parts and assemblies. This service can also include the glueing of two or more parts.
  • Quality Testing: Rigorous testing procedures are conducted to ensure that parts meet specified requirements. Additionally, we offer First Article Inspection (FAI), which involves a detailed examination and testing of the first part produced from a new manufacturing process to verify that it meets all specifications and quality requirements.
