What DHR Engineering does

DHR Engineering is a private industrial automation integrator founded in 2016, headquartered in Bulgaria (Sofia, with listed Plovdiv origin) and operating a US office in Los Angeles, California. The company designs and deploys custom automation systems for advanced manufacturing, with core capabilities spanning robotics integration, PLC and control systems, CNC machine tending, automated tool preparation, and proprietary 3D print farm automation. Its technology stack combines custom robotic workcells, in-house hardware (e.g., bed-handling robots, vertical lift module filament carousels, REGO-FIX-integrated tool holder assembly cells), and a proprietary Fleet Orchestration & MES middleware that delivers real-time job scheduling, automated failure recovery, and API-based ERP/MES integration across FDM, SLA, and SLS printer fleets from multiple OEMs (Bambu Lab, Formlabs, LuxCreo, Stratasys, 3D Systems, Asiga, Prusa). The company emphasizes brand-agnostic integration, claiming deployment timelines one-quarter those of competing integrators, on-site engineering presence of 50% of project time, and sub-12-hour emergency response, with deployed systems reportedly achieving >95% uptime and near-zero unplanned downtime.

DHR serves two primary customer segments: VC-backed hardware startups (such as Durin Mining, Tundra Drone, Rainmaker Technology, Growcer AG, and Formlogic) needing rapid, scalable production automation, and established manufacturers modernizing existing operations for lights-out production. Industry verticals include aerospace, dental, defense/drone manufacturing, mining, and agriculture. Revenue is generated through professional services (project-based custom automation engagements with multi-year contracts and a typical 14-week deployment timeline) and hardware sales (proprietary robotic workcells, end-effectors, and middleware software). Pricing is quote-based and not publicly disclosed. The company has deployed 50+ custom automation projects since inception and has recently expanded into outdoor industrial robotics and direct-print dental aligner production. The company remains privately held and founder-led by Dimitar Hristakiev, with no disclosed institutional funding to date.
