Mantle appoints new VP of Sales and VP of Manufacturing
October 29, 2021

Mantle, an Additive Manufacturing startup based in San Francisco, California, USA, reports that it has strengthened its leadership team with the appointment of Dana McCallum as its vice president of Sales and Mark Sloan as its vice president of Manufacturing. Both McCallum and Sloan are said to bring decades of experience launching and bringing products to market.
McCallum joins Mantle after six years at Carbon, a leading plastic AM company, where she was the first person in the company’s sales organisation and went on to develop and lead the Carbon Production Network, an ecosystem of injection moulders and service bureaus offering part production services with Carbon’s technology. McCallum started her career at Thogus, a custom injection moulding company, where she held roles in marketing and programme management. McCallum serves on the board of Women in 3D Printing and the Society of Plastics Engineering Additive Manufacturing group. She is a past vice president of the Additive Manufacturing Users Group and recipient of its prestigious Distinguished Innovator Operators Award.
“Dana brings a unique combination of experience in injection moulding, toolmaking, and Additive Manufacturing,” stated Paul DiLaura, Mantle’s Chief Commercial Officer. “Dana’s leadership will help us establish strong partnerships with our customers and support their efforts to change their tooling processes to lower lead times, costs, and cycle times.”
McCallum commented, “I have devoted my career to helping manufacturers realise value through new technologies. I joined Mantle because of our unique technology and focus on the tooling market. By helping toolmakers, moulders, and OEMs produce their precision tooling components in a fraction of the time and cost of traditional manufacturing or other 3D printing processes, Mantle is poised to redefine toolmaking and help manufacturers develop and launch new products faster than ever before.”
Sloan joins Mantle after nine years at Sentient Energy, an IoT utility sensor company that was acquired by Koch Industries in 2020. Sloan built Sentient’s manufacturing organisation and served most recently as its executive vice president of Manufacturing after serving as its executive vice president of Engineering. Sloan previously served as the vice president of Operations at Finesse Solutions, a life sciences sensor company that was acquired by Thermo-Fisher. Sloan started his career as a Manufacturing Engineer at companies such as 3Com and Agilent Technologies.
“I have commissioned hundreds of tools throughout my career and I understand first-hand how lengthy and expensive tool development cycles can be – and how they slow product development and launch schedules,” stated Sloan. “I am excited to scale up production of Mantle’s precision metal 3D printing solution while developing our supply chain so we can help our customers change how they design and develop their tools.”
“Dana and Mark bring tremendous experience to our organisation and to our customers,” added Ted Sorom, Mantle’s CEO and co-founder. “Mark will ensure that we bring our first systems to market in 2022 while instilling rigorous quality and reliability standards. Dana will ensure strong customer partnerships from initial launch to widespread adoption. After emerging from stealth earlier this year and announcing our Series B financing last month, adding experienced executives like Dana and Mark is the next critical stage in our development that will support our long term growth.”
