Croft Additive Manufacturing

3D Printing of Complex Metal Parts

Croft Additive Manufacturing is a specialist company that provides Stainless Steel 316L metal additive manufactured (AM) parts to a range of industries: from Motorsport and Manufacturing to Art and Fashion. Based in Warrington, England, Croft offers an innovative and flexible approach to supplying Customers with AM products.

At Croft our aim is to supply industrial additive manufactured components to our customers, helping them to fully utilise the technology to suit their individual needs and to solve their unique problems. To work as a team to deliver exceedingly high quality of both products and service, rewarding staff accordingly.

Benefits of the additive process such as: Part Weight Reduction, Multi-part to Single Component and Expanded Design Capabilities allow our Customers to re-think their approach to their designs in order to improve the efficiency, utility or aesthetics of their parts.

How does SLM Additive Manufacturing Work?

The process starts with CAD model (in either .stl or step -.stp or .igs format). The model Is assessed in-house whether it can be built using the AM process and is developed to fully utilise the advantages of AM, if this is desired by the customer.

The CAD model is then sliced into even layers, in a range 25-50 micron depending on the part. This file is the uploaded onto the Selective Laser Melting AM machine.

The build plate is then heated to 200℃ as the pressure increases slightly within the build chamber. An inert gas is introduced within the chamber as the oxygen levels decreases by 0.2%.

A fine layer of powder is then extruded up onto the build plate, being even distributed by a wiper blade; this layer corresponds with the first slice of the CAD file.

A high powered laser then melts the metal powder according to the CAD design.

Once the first layer is complete, the build plate drops according to the layer size. Another layer of powder is then added over the first layer.

The second layer is then melted over the first according to the CAD file. The process is then repeated until the part is complete.

Usually the surface roughness of an AM part is rougher than that of machined parts. Surfaces that require specific finish/surface roughness should be identified before start of build. Finishing processes availably include: sand blasting, vibratory finish, tumble finish and others on request.
