What Castheon does
Castheon, founded in 2016 and now operating as part of ADDMAN Engineering LLC under the ADDMAN Advanced Metals brand, is a metal additive manufacturing specialist headquartered at its Thousand Oaks, California facility. The company provides metal additive manufacturing services using Laser Powder Bed Fusion (LPBF) and has developed proprietary capabilities in print parameter and material development for advanced metallurgy, including refractory alloys, superalloys such as Niobium C103, nickel-based alloys, and titanium alloys. Castheon's capabilities have been integrated into ADDMAN's broader manufacturing platform, which spans eight U.S. facilities offering metal AM, polymer 3D printing (MJF, FDM, SLA, DLP, SLS, DLS, PolyJet, HPS), injection molding, precision CNC machining, urethane casting, and full lifecycle engineering services from prototype through production.
The combined entity holds a comprehensive set of quality certifications including ITAR registration, AS9100D, NADCAP, ISO 13485, ISO 9001, ISO 14001, and ISO 50001, qualifying it to serve regulated industries. ADDMAN also markets ADDCAAM, an award-winning proprietary software platform for additive manufacturing design and process optimization. The company's primary verticals are Aerospace & Defense, Commercial Space, and Medical, with secondary exposure to Energy and Industrial markets; key applications include hypersonic components, propulsion thrusters and nozzles, thermal management parts, and patient-specific anatomical models.
Castheon/ADDMAN operates an enterprise field sales and inside sales motion with quote-based, project-by-project pricing, multi-year contracts, and no publicly disclosed standard pricing. Revenue is generated entirely from custom manufacturing services, with no software licensing or product sales of note. Customers engage directly through enterprise sales outreach and website lead capture, supported by content marketing (resource library, blog, webinars, podcasts, trade shows) and a nationwide manufacturing footprint that allows the company to serve domestic customers primarily while supporting international requirements via ITAR registration.

Castheon competitors and assessment
Company assessmentDirect peers
- EOS GmbH: EOS is a global leader in industrial metal and polymer AM systems and services, with deep aerospace and medical verticals. It is comparable to Castheon/ADDMAN as a competitor offering LPBF service capacity alongside machine sales to regulated industries.
- Velo3D: Velo3D is a US-based metal additive manufacturing specialist focused on LPBF systems and contract manufacturing services for aerospace, defense, and space customers. It directly competes with Castheon/ADDMAN in titanium and nickel-superalloy LPBF service work for mission-critical applications.
- SLM Solutions (Nikon SLM Solutions): SLM Solutions (now owned by Nikon) provides metal LPBF systems and offers contract manufacturing for aerospace, automotive, and medical customers. Its multi-laser LPBF technology and aerospace customer base overlap directly with Castheon's metal AM services offering.
Emerging players
- Titomic: Titomic is an Australian kinetic fusion (cold-spray) additive manufacturing company with defense and aerospace exposure. It is both a Castheon/ADDMAN strategic partner and an adjacent emerging player in non-thermal metal AM, addressing similar aerospace/defense customers.
- Amaero International: Amaero is an Australian-listed emerging metal AM player specializing in refractory alloys (including Niobium C103) and titanium for aerospace and defense. It is a direct emerging competitor to Castheon's refractory/superalloy niche and was specifically cited in the source data.
- Markforged (now part of Nano Dimension): Markforged offers metal and composite industrial 3D printing systems and services, with growing aerospace and defense adoption. It overlaps with Castheon/ADDMAN in production-grade metal AM for regulated industries but typically at smaller part sizes.
Broad incumbents
- 3D Systems: 3D Systems is a broad incumbent 3D printing OEM and services provider with metal (DMP), polymer, and advanced materials capabilities serving aerospace, defense, and medical. It competes with Castheon/ADDMAN across multiple AM modalities rather than specializing in metal refractory alloys.
- Stratasys: Stratasys is a broad incumbent in polymer 3D printing (FDM, PolyJet, SAF) with growing aerospace and defense exposure through its acquisition of aircraft-class parts operations. Comparable to ADDMAN's polymer printing division (formerly Forecast 3D, now integrated).
- Desktop Metal (incl. ExOne): Desktop Metal is a broad AM platform offering binder jetting, production systems, and metals services including through its ExOne acquisition. It is comparable as a metals AM services competitor with diversified end-market exposure across automotive, aerospace, and industrial.
Regional players
- BeamIT: BeamIT is a European metal AM service bureau operating multiple LPBF and EBM machines, serving aerospace, motorsport, and medical customers. It is a regional services peer with comparable metal AM service offerings to Castheon/ADDMAN but operating primarily in EMEA rather than the US.
