Precision Machining Firm Adds Metal 3D Printer to Manufacture Parts without Redesign

CAMPBELL, Calif.–Eyeing applications in oil, gas, and aerospace, precision tool and component manufacturer Knust-Godwin recently purchased its first VELO3D Sapphire metal additive manufacturing (AM) system. The VELO3D’s SupportFree metal additive capabilities complement Knust-Godwin’s core competency of precision machining and are expected to enable the company to manufacture “even more complicated geometries,” Knust-Godwin said in a news release.

Known for its capabilities to consistently produce high-quality parts with low-angle geometries without support structures, the VELO3D system consists of FlowTM advanced pre-print software, Sapphire printer, and AssureTM quality management software. It will join Knust-Godwin’s existing fleet of seven metal AM machines in Katy, Texas. Knust-Godwin ( said that it will take delivery of the Sapphire printer in the first quarter of 2020 and has already secured customer orders to print end-use parts for the oil service industry.

“We see so many parts that have been manufactured with traditional methods that could take advantage of the benefits from AM,” said Michael Corliss, vice president of technology for Knust–Godwin, in the release. “Our new Sapphire system provides the accuracy and low-print-angle capabilities that enable recreation of those parts via AM without having to go through a complicated redesign process. We can finally print parts as-is, offering valuable cost-savings to our customers and improved turnaround time for delivery.”

Velo3D’s SupportFree capability for metal 3D printing is said to enable design innovation by reducing the need for support structures in metal additive manufacturing. The company’s Sapphire® system is said to be built with a semiconductor mindset on quality assurance, ensuring repeatability and dependability throughout serial manufacturing.

“The oil and gas industry is one of the largest emerging market segments to adopt metal AM, and I’m thrilled to partner with oilfield leaders like Knust-Godwin for direct-part production,” said Benny Buller, founder and CEO of VELO3D. “Their extensive background of over 50 years in precision machining, combined with their additive production experience, means that they understand what it takes to close the gap between prototyping and serial manufacturing.”

Oil and gas applications share requirements with aerospace for intense thermal management of extreme temperatures, complex geometries, and expectations of cost-control and rapid delivery of parts. Knust-Godwin recently achieved AS9100 certification and is now expanding its capabilities to address the needs of the aerospace industry. The company specializes in CNC turning and CNC milling. Besides the oil and gas industry, Knust-Godwin said that it has significant experience in the geophysical/seismic, semiconductor, and medical industries.
