About The Position

Physical Intelligence is developing general-purpose AI for the physical world. The Robotics Technician Team works with fleet operations and engineering to maintain robotic platforms used in AI research. The 3D Printer Technician owns additive manufacturing for the team and partners with hardware engineers, prototype technicians, and robot service technicians across multiple locations. The role includes operating and maintaining printers at every location, managing the print-request queue, setting and maintaining print standards, and ensuring each site has stocked printed spare parts. The technician verifies that requests use released Onshape models, prioritizes work based on robot downtime and production builds, and communicates queue status. The role also covers printer preventive maintenance and repair, materials inventory, post-processing and inspection, printed-parts documentation, stock management, access administration, technician training, and monthly reporting on uptime, print volume, and failures.

Requirements

At least 2 years of experience running FDM printers in a production, lab, or service environment, including maintenance and repair.
Fluency with Bambu Studio, PrusaSlicer, Cura, or an equivalent slicer; ability to build and tune profiles from scratch and explain settings.
Ability to open CAD models, check dimensions, repair meshes, and adjust print tolerances.
Comfort using calipers and working with heat-set inserts and threaded hardware, and inspecting parts to a drawing.
Comfort splitting time between locations and owning printer uptime at sites not visited every day.
Attention to detail and ability to hold parts to a standard and track print failures.
Clear written communication for queue updates and failure reports, and effective cross-functional communication with hardware engineers, prototype technicians, and robot service technicians.

Nice To Haves

SLA or SLS printing experience.
Onshape experience.
Experience using the Linear ticketing system.

Responsibilities

Own and manage the print request queue in Linear, capturing part, revision, quantity, material, requester, and need-by date.
Prioritize print requests, giving priority to robot downtime and then production builds.
Verify that each request references a released Onshape model and return undocumented parts to the requester.
Post daily queue status, including current work, upcoming work, blockers, and expected ready times.
Operate printers at all locations, including slicing, bed preparation, starting and monitoring prints, removing parts, and recovering from failed prints.
Create and execute preventive maintenance schedules for printers at each location, log maintenance, and diagnose and repair printer failures.
Maintain site spares kits and respond to printer outages so down printers can return to service the same day.
Travel between locations on a set cadence for preventive maintenance, repairs, and calibration.
Track and report printer uptime by location monthly.
Manage filament and resin inventory, including stock levels, dry storage, reorder points, and purchasing within set limits.
Maintain standard, versioned print profiles for each material and part family.
Post-process parts to their drawings, including support removal, heat-set inserts, hardware, and finishing, and inspect parts with calipers before release.
Maintain site stocks of printed spare parts to established minimums for high-turn parts.
Maintain a printed-parts library covering part number, revision, material, profile, print time, use, and stock at each site.
Track print volume and failure rates by part and printer, and report monthly on negative trends.
Own the printer access list and train technicians with print access on standard workflows and profiles.
Follow the team's ticket closeout and handoff guide for every print ticket.
