Relativity Space Machine Shop · Metal Additive

Rockets are built in microns, not mission statements.

Orbit Ready: bite-sized, decision-grade lessons for the machinists, engineers and technicians who print rocket-engine hardware in metal powder and finish it on CNC. Ten weeks from needs analysis to implementation. Built for people who move fast and cannot afford imprecision.

LAYER BY LAYER

A rocket engine is a long argument with physics, settled one tolerance at a time.

In a powder bed fusion printer, a laser draws a slice of a part into a bed of fine metal powder, the bed drops a fraction of a millimetre, a fresh layer is spread, and the laser draws again. Thousands of times. What comes out is close. Close is not flight hardware. The CNC shop takes it the rest of the way.

Two disciplines, one part, and a hand-off in the middle where mistakes like to hide. I learned in aviation that the most dangerous moment in any system is the handover. The machine shop is no different.

So the brief was not “teach people about 3D printing.” It was: give every operator on either side of that hand-off the same picture of the part, and the same standard for calling it done.

00 // The terrain

Two machines, one part

Additive builds it. Subtractive makes it true.
Powder bed fusion · metal AM

Grow the geometry

A laser fuses metal powder layer by layer inside an inert chamber. It makes internal channels and organic shapes that no cutting tool could reach. It also brings its own risks: porosity, residual stress, distortion and powder handling.

Core verb · Build
CNC machining · subtractive

Hold the tolerance

Printed parts arrive near-net. Mating faces, sealing surfaces and datums still have to be cut, measured and proven. Fixturing a printed part is its own skill, because no two arrive quite the same.

Core verb · Prove
Powder to part

Where the training had to hold

The training followed the part, not the org chart. Every station is a place where an operator makes a call the next station has to live with.

01 · Prepare

Powder & build file

Powder condition, orientation, supports. Most print failures are decided here.

02 · Print

Laser fusion

Layer by layer in an inert atmosphere. Monitor, don’t assume.

03 · Relieve

Heat treat & depowder

Release the stress the print locked in, and get every grain of powder out.

04 · Machine

CNC finish

Remove supports, fixture the near-net part, cut critical features to print.

05 · Prove

Inspect

Measure against the drawing. The part is done when the evidence says so.

01 // The gap

What the shop was carrying

Mapped before a single screen was built

A team moving at launch-company speed, adopting a manufacturing process younger than most of its tooling. The gap was not effort. It was a shared picture.

Skills gap

New process, uneven fluency

Critical gaps in advanced manufacturing technique, most of all in metal additive printing.

Mixed experience

One shop, many starting points

Veteran machinists, new technicians and engineers, each arriving with a different map of the work.

Language

Engineering speak, shop-floor need

Complex aerospace documentation had to become something an operator could act on at the machine.

02 // The build

Ten weeks, four phases

SMEs in early. Rework stays out.
Phase 01 · Analyse

Read the shop before writing the course

Needs analysis with the machine shop. Internal SOPs reviewed, new manufacturing workflows and aerospace standards analysed.

Phase 02 · Design

Build with the engineers, not around them

Close collaboration with engineering SMEs and the Talent Development team. Templates set to engineering documentation standards and corporate brand guidelines.

Phase 03 · Develop

Bite-sized, modular, illustrated

Interactive lessons in Storyline 360 and Rise 360 with technical illustrations and animations, supported by an AI toolkit. No voice-over, so any module can be updated without re-recording.

Phase 04 · Implement

Ship on schedule, refine on feedback

Every module delivered on time, with stakeholder approval at each milestone and a feedback loop built in for continuous improvement.

03 // Evidence

What we measured, and what moved

Instruments
  • 01Pre- and post-assessments
  • 02Error-rate reduction metrics
  • 03Workflow efficiency benchmarks
  • 04Stakeholder sign-off at every milestone
Outcomes
  • 01Reduction in manufacturing errors and rework
  • 02Wider adoption of additive manufacturing protocols
  • 03Improved production timelines
  • 04Stronger quality control on the floor
Doctrine
Completion is not capability. The part either holds tolerance or it doesn’t.

A finished lesson proves someone reached the last screen. A part that passes inspection the first time proves something crossed from the course to the machine. Only one of those flies.

Fonts, headers and layouts followed engineering documentation standards, so the course looked like the drawings and work instructions operators already trust. Leaving out voice-over was a deliberate call: in a shop where the process changes monthly, a lesson you can’t update is a lesson that starts lying.

04 // Debrief

Questions worth asking

Manufacturing engineers, CNC machinists and aerospace technicians working on rocket engine production and additive manufacturing.
Increase precision and efficiency in rocket engine production by giving teams current training on CNC machining and metal 3D printing.
Translating complex aerospace engineering language into training an operator could use at the machine, without losing the precision the engineering demands.
Bring the SMEs in early. Close collaboration at the start reduced rework and protected accuracy. Every hour with an engineer in week one saves a day in week nine.
Direct collaboration with engineering teams, internal SOPs, and analysis of new manufacturing workflows and aerospace standards.
Yes. Roughly ten weeks from needs analysis to implementation, every module on schedule, with stakeholder approval at each milestone.
Engineering in. Capability out. Evidence always.

Training that ends at the inspection bench, not the completion screen.

The course is live. Open it and work through it the way an operator would: one part, one setup, one decision at a time.
