Additive Manufacturing Operator

The operational workflow demands meticulous powder bed preparation inside inert argon gas atmospheres to prevent violent powder oxidation and porosity defects. The operator levels the powder recoater blade, verifies build plate substrate parallelism, measures powder moisture content, and inspects optical laser protective windows. During high power laser melting, the operator monitors build chamber pressure, oxygen parts per million ppm levels, melt pool thermal emissions, and recoater wiper resistance to catch catastrophic blade crashes before entire multi day builds are ruined.

Following build completion, the operator performs hazardous powder handling, vacuum recovery, and depowdering inside dedicated containment gloveboxes while wearing powered air purifying respirators PAPR. The operator coordinates electrical discharge machining EDM wire cutting to sever printed components from the build plate, and oversees thermal vacuum stress relief heat treatments. While build slicing software and AI driven melt pool monitoring tools assist in defect detection, the hazardous physical handling of combustible micron sized metal powders, precision mechanical machine setup, recoater blade leveling, and metallurgical quality inspection necessitate certified human additive manufacturing technicians.

At 07:00, the operator suits up in antistatic safety coveralls, grounding straps, and a powered air purifying respirator PAPR before entering the metal additive production lab. Today an aerospace turbine bracket build comprising twelve titanium Ti6Al4V components is slated to run on the EOS M 290 printer. The operator secures a heavy ground titanium build substrate to the machine z axis elevator, utilizing a precision micrometer dial gauge to tram the platform flat within ten microns across its 250 millimeter square surface. Installing a fresh silicon carbide recoater blade, the operator dials the clearance to forty microns and fills the

powder dosing hopper with forty kilograms of certified sieved titanium powder under an argon blanket. Closing the heavy build chamber door, the operator initiates the vacuum purge sequence, monitoring the digital sensor as argon gas displaces atmospheric air until oxygen levels plunge below twenty parts per million. Starting the dual 400 watt fiber lasers, the operator observes the initial thirty layers through the green safety viewport, verifying smooth spatter ejection and zero recoater blade chatter. Later in the afternoon, the operator moves to depowdering station two, recovering an Inconel 718.

An Additive Manufacturing Metal Laser Powder Bed Fusion Operator prepares, operates, monitors, and post processes high precision metal 3D printing systems utilizing Selective Laser Melting SLM and Direct Metal Laser Sintering DMLS technologies. Working primarily in aerospace, biomedical implant, motorsport, and specialized defense manufacturing facilities, the operator transforms fine reactive metal powders such as titanium Ti6Al4V, nickel superalloys Inconel 718, and medical grade cobalt chrome into complex geometric parts that cannot be produced through conventional subtractive machining.

Core responsibilities include set up, calibrate, and operate multi laser powder bed fusion metal 3d printing systems., operational coordination, and ensuring strict adherence to Kenyan statutory frameworks and quality standards.

Key organizations hiring for this role include Kenya Bureau of Standards KEBS, National Construction Authority NCA, KenGen Kenya Electricity Generating Company, Safaricom PLC, alongside expanding opportunities in Nairobi, Mombasa, Kisumu, and regional infrastructure projects.
