Direct (Rapid) Manufacturing is producing in series using production methods which are on line or indirectly connected with engineering. For this Mareco uses SLS; production batches go directly from the CAD-station to the production machine.
Mareco Prototyping uses SLS to produce functionally useful items from the thermoplastic polymer PA12:
no mould costs
super fast
with various standard colours
The lack of mould-costs is particularly interesting for small series. But perhaps even more important for you is the lead-time: one week on average per production-batch.
Ideal for the initial phase, but in small numbers in many cases also for the lifetime of your product.
