Sintermask operating costs
Running a high end RP system can be an expensive business as there are the infrastructure costs, capital costs and process consumable costs to consider.
Selective Mask Sintering (SMS) aggressively attacks all three categories whilst at the same time boosting productivity to further reduce 'cost per part'.
From an infrastructure perspective three phase power is a requirement however, there is no need to provision a nitrogen supply either from bottles or from a generator.
The equipment does not utilise expensive lasers and scanning systems either, reducing initial purchase cost and ongoing maintenance fees. The infrared lamps used to sinter the powder have a stable characteristic up to their recommended 3000 hour life, at which time they can be swapped out at a very economical rate.
The mask is created using 'printer and toner technology' and whilst this has a service life, it is fully covered under the maintenance contract, with exchange being possible in less than half an hour.
Powder costs, possible the biggest consumable element, are a function of material used. However, as a benchmark, the process offers a low refresh rate on the standard nylon of around 15-20%, thus reducing cost and waste at the same time.
Hence when combined with a build speed that is approaching three times that of laser sintering, it is easy to see why SMS establishes a new price point for functional prototypes and further advances the implementation of Rapid Manufacturing.
