About The Position

We are seeking a highly skilled and detail-oriented 3D Printing Technician to oversee our multi-technology additive manufacturing technologies. You will be responsible for the end-to-end production workflow, from digital file preparation to advanced post-processing, across our FDM, SLS, SLA, and PolyJet systems. This role ensures maximum machine uptime, high-quality part output, and efficient material management.

Requirements

3+ years of professional experience in an additive manufacturing environment.
Deep understanding of the distinct mechanics and material behaviors of FDM, SLS, SLA, and PolyJet.
Experience with CAD software (SolidWorks, Autodesk) and industry-standard slicing tools.
Strong mechanical and electrical troubleshooting skills to diagnose printer hardware issues.
Ability to collaborate with engineers and designers to advise on "Design for Additive Manufacturing" (DfAM).
Able to lift 40 lbs. and handle the physical demands of a workshop environment.

Responsibilities

Manage the daily print queue for all four technologies, ensuring projects stay on schedule.
Prepare digital models using slicing and build-preparation software (e.g., GrabCAD Print, PreForm, Magics).
Optimize print parameters for each technology to balance speed, surface finish, and mechanical integrity.
Perform regular bed leveling, nozzle replacements, and belt tensioning for FDM printers.
Manage powder handling for SLS printers, including sieving and refreshing used powder with virgin material.
Maintain resin tanks, calibrate UV lasers/light sources, and ensure clean optical paths for SLA printers.
Perform print head cleanings, monitor waste levels, and handle high-precision multi-material cartridges for PolyJet printers.
Execute technology-specific post-processing: support removal (FDM/PolyJet), bead-blasting (SLS), and IPA washing/UV curing (SLA).
Inspect finished parts for dimensional accuracy and surface quality against design specifications.
Maintain detailed logs of machine performance, maintenance history, and print failures.
Manage stock levels for filaments, powders, resins, and specialized PolyJet materials.
Ensure a safe working environment, including proper handling and disposal of chemicals (resins/IPA) and powders.
Coordinate with equipment vendors for advanced repairs and service contracts.
