3D printing claims parity with injection molding

03/07/2014

Rapid manufacturing proponent 3D Systems (3DS; Rock Hill, SC) has made the broad claim that its stereolithography (SLA) and selective laser sintering (SLS) 3D manufacturing printers can match the productivity of traditional injection molding in the direct manufacture of functional parts.

To prove its point, the company released a video on Youtube showing production of mini lamp shades at the rate of 2400 for 20 hours, translating to 30 seconds per part. 3DS says it is debuting a series of videos that demonstrate how its fab-grade printers can manufacture thousands of parts at speeds comparable to traditional injection molding operations. The first one features what appears to be the skeptical boss of an injection molding firm visiting 3DS' headquarters to break the news that injection molding productivity will never be surpassed by 3D printing.
