“I applaud Sigma for its transformation from Sigma Labs to Sigma Additive Solutions. While the
company spent years improving upon its roots as a significant player, it has been obvious
to our team that Sigma is poised to become a leading provider of quality solutions and data
pedigree that that solves key challenges to enable adoption of additive manufacturing at scale
across the value chain. We look forward to developing our strategic partnership with Sigma
Additive Solutions through a joint value proposition, to improve the economics and efficiency of
individual customers while seeking to accelerate the growth of the AM industry.”

“We are pleased to have Sigma Additive Solutions as a founding member of our AM CoE
Industry Consortium on Materials and Standardization (CMDS) and look forward to
collaborating on standardizing the best practices for materials data generation and creating,
curating, and managing the data needed to accelerate the industrialization and full adoption of
AM technologies. Sigma's focus on solutions could not come at a better time for the industry.”

“Perhaps the biggest obstacle to widespread AM adoption is quality control…Meanwhile, firms
like Sigma Labs…have created hardware to monitor the build chambers of metal 3D printers to
detect errors. Increasingly, these tools will enable active feedback so that the machines can
quickly correct issues during the print process. When connected with MES software and 3D
printing simulation, the equipment can learn from past errors and address them before they
even happen in the future.”

“Five months ago, we jointly announced that with Sigma technology integrated on our Control
Platform one of the most common roadblocks for manufacturers, interested in using metal
additive manufacturing for serial production, can be eliminated through a closed loop control.
This makes it possible for customers to leverage their expertise and take advantage of the
customization and localization benefits that AM provides.”
