Technology & Products
Key Products
3D printed sand cores; 3D printed sand molds; Conventional cold-box sand cores; Conventional air-set sand molds; Hybrid conventional/additive manufacturing solutions
Technological Advantage
Proprietary expertise in sand binder jetting process optimization for high-volume production; Verified advantage: Largest manufacturer of 3D-printed sand cores/molds in North America with fleet of industrial 3D sand printers.
Differentiation
Value Proposition
Reduces lead times from months to days by printing toolingless sand cores/molds, enabling rapid prototyping and production while bypassing traditional tooling bottlenecks.
How They Differentiate
3x faster lead time elimination vs traditional tooling (days vs months); Hybrid conventional/additive capability allows dual-path manufacturing while competitors typically focus on one approach.
Market & Competition
Target Customers
Foundries and original equipment manufacturers (OEMs) in automotive, aerospace, industrial equipment, and racing industries
Industry Verticals
Metal Casting; Automotive; Aerospace; Industrial Equipment; Racing
Competitors
Hoosier Pattern Industries; TEI (aerospace-focused); Sculpteo; CINI; JuggerBot 3D

HumTown Additive occupies a unique hybrid position in metal casting: it operates both conventional cold-box and air-set sand core production alongside a fleet of industrial binder jetting printers. Founded in 1959 as a pattern shop, the company began its additive transition in 2014 through a partnership with Youngstown State University, receiving its first 3D sand printer. By 2020 it had won the NAM Manufacturer of the Year award and claims the largest 3D sand printing production capacity in North America.
The core service is binder jetting of sand cores and molds directly from CAD files, eliminating the weeks or months required to produce traditional tooling. This enables foundries and OEMs in automotive, aerospace, industrial equipment, and racing to prototype and produce metal castings with dramatically shorter lead times. HumTown's hybrid model allows customers to choose between additive-only, conventional-only, or combined approaches depending on volume and complexity requirements.
Revenue grew 24% year-over-year in 2023 to approximately $13 million, with 28 employees. The company has raised $15.41 million from private investors. In 2024 it relocated to a larger Boardman, Ohio facility with atmospheric controls, signaling continued investment in production scale. Key partnerships include America Makes, the Cybersecurity Manufacturing Innovation Institute, and the Additive Manufacturing Coalition.
Competitive risks include the potential for large foundries to internalize sand binder jetting as printer costs decline, and competition from other service bureaus like Hoosier Pattern Industries and TEI. HumTown's hybrid capability and decades of conventional casting expertise may provide a moat, but the open question is whether additive-only competitors can match its dual-path flexibility at lower price points.
