Additive manufacturing

Laser sintering

EOS P800

  • The EOS P800 is the first Additive Layer Manufacturing (ALM) System which can process high temperature thermoplastics. 
  • This system is a powdered bed process, scanning each layer using a CO2 Laser. It has a build volume of 700 x 380 x 580mm (x, y, z).
  • Materials: Unreinforced PolyEtherKetone (PEK), semi crystalline high performance thermoplastic material.
  • Applications: high strength and stiffness as well as good ductility at higher temperatures. Chemically resistant to aggressive environments, suitable for sterilization for medical and food contact applications.
  • CALM is proud to be the first owners of an ALM system like this within the UK.

EOS P100 Formiga

  • The EOS P100 was first released in 2008 with the focus of manufacturing in mind. The P100 is designed for easy of material change, part manufacture and repeatability.
  • This system is a powdered bed process, scanning each layer using a CO2 Laser. It has a build volume of 200 x 250 x 330mm (x, y, z).
  • Materials: High performance thermoplastic; either polyamide 11 or 12, reinforced or unreinforced.
  • Applications: Ideally used to manufacture parts for functional testing, design communication and tooling applications. Can withstand high mechanical and thermal loads.

DTM 2000 SinterStation

  • The DTM 2000 was one of the first Laser Sintering (LS) systems released in the late 1980s.
  • It has now been superseded, however the basic fundamentals of LS are still the same and this system is used as a research tool to develop new materials and understanding of the LS process.
  • It has a build volume of 320mm in diameter and 380mm high.

 

Material extrusion

Stratasys Dimension 768

  • This FDM system deposits material through an extrusion head layer by layer following a deposition path.
  • It has a build volume of 203 x 203 x 305mm (x, y, z).
  • Materials: Acrylonitrile butadiene styrene (ABS)
  • Applications: Ideally used to manufacture parts for functional testing, design communication, tooling and final part applications. It also has FDA certified one of its materials for medical devices.

3D Systems Projet HD 3000

  • This FDM system produces components within hours, creating highly defined details on parts using 3D printing techniques to deposit material onto a platform, building up the part layer by layer.
  • It has a build volume of 300 x 185 x 200mm (x, y, z).
  • Materials: A range of Acrylate thermoplastics
  • Applications: Ideally used to manufacture parts for functional testing, design communication and tooling applications. Material can also be used to cast.
Powder analysis 

Freeman FT4 Powder Rheometer

  • The FT4 Powder Rheometer is used to characterise the rheology or flow properties of powders.
  • It is able to measure the bulk properties such as density, compressibility and permeability as well as the powder's resistance to flow, whilst also analysing shear strength and quantifying how a powder shears with respect to the surfaces of process equipment.
