Custom 3D printing for the shop floor

We engineer the fix your line has been missing.

Lean Forge designs and 3D prints custom material handling and workstation solutions for manufacturing teams — built to cut wasted motion, protect inventory in transit, and keep your process lean.

What we do

Material handling solutions, engineered by people who've stood on the line.

Standard catalog parts aren't built for your process — they're built for the average one. Lean Forge designs and 3D prints custom fixtures, bins, and protective solutions specifically around the way your operators actually work, targeting the wasted motion, damage, and downtime that a generic bin or foam insert never will.

We work in the language of lean manufacturing: every custom part we design is aimed at eliminating a specific, measurable form of waste — motion, defects, or wait time — not just making something that looks nice on a shelf.

Part Retrieval

Bin and fixture geometry designed to cut seconds off every pick, and minutes off every shift.

Product Protection

Custom-fit packaging and transport fixtures that stop damage before it costs you a replacement.

Workstation Organization

Fixtures and holders built around your actual layout, not a generic rack size.

Featured solutions

A couple of the problems we've already solved.

These started as one-off fixes for our own production line. They worked so well we're now offering them — and the process behind them — to other teams.

Our process

From "this is annoying" to a part in your hand.

We keep the process short on purpose — the whole point is speed and fit, not a long design cycle.

Spot the waste

We identify the specific motion, damage, or delay costing your team time — usually something everyone's just gotten used to living with.

Design & prototype

We model a fix and 3D print a working prototype — fast, so you're testing something real within days, not weeks.

Field test

The prototype goes straight to the floor with real operators, in real conditions. We refine based on what actually happens, not assumptions.

Deploy & refine

Once it earns its place on the line, we finalize the design and keep iterating as your process changes.

Where it started

Built by two people who got tired of watching the same problems happen every shift.

Both of our first products came out of real time spent on the floor — not a design brief, but a recurring, obvious frustration. One of us kept watching operators struggle to pull small parts from shallow bins. The other kept watching gaskets arrive damaged after nothing more than a walk between departments.

Neither problem had a product on the market built to solve it. So we engineered our own — and now we're bringing that same approach to other teams dealing with the exact same kind of problem, whatever it looks like on your floor.
