Having operated in the filtration market for over 30 years, Croft Filters has provided various filter designs to wastewater treatment plants.
Croft specialise in the Additive Manufacture (3D Printing) of complex metal filtration solutions and other components.
AM Design freedoms enable components to be designed and built to add value such as improved performance, light weighting, multi-part to single part, low volume production runs, prototyping, reverse engineering and supply chain value.
Benefits of metal 3D printing
Benefits of the Additive process, such as:
- Part weight reduction
- Multi-part to single component
- Expanded design capabilities
All allow our customers to re-think their approach to their filtration designs in order to improve the efficiency of their parts.
What is Additive Manufacturing?
Additive Manufacturing (AM), also known as 3D printing, is the process of manufacturing components through the addition of material in a series of layers melted or fused together to create the part. This process allows complex parts to be built as a single component and can deliver additional benefits that conventional manufactured parts could not.
Croft specialise in Selective Laser Melting, a Powder Bed Fusion process that constructs components through layering metal powder, fusing the powder within each layer according to the CAD file.
The process uses a metallic powder, for example, Stainless Steel 316L. The powder is spread evenly across a build plate, the laser then melts the powder according to the CAD data. The build plate then drops and another powder layer is added. The laser then melts this layer to the previous layer.
The process is repeated until the final part is complete.
Improving filtration efficiency can be a challenge. Especially for companies that are trying to deliver the highest possible open area across the filter media.
