RBSL has been actively engaged on Project TAMPA for the past 3 ½ years throughout spirals 1, 2, and 3. Under the three spirals, RBSL have developed suitable internal/external processes to manufacture 10 separate parts for the Warrior, Panther, Titan, Cr2 and Terrier armoured vehicles. All parts to date have used the LB-PBF and SLS additive manufacturing techniques, however RBSL also have the in-house capability to manufacture using a metal paste deposition technique as well as numerous polymer AM systems. Capabilities in design for AM, FEA for AM, advanced generative design and topology optimisation have been developed during Project TAMPA. RBSL will be presenting the lessons learnt from Spirals 3a and 3b.
