What do you need in your shop floor to install an LPBF machine?

The conversation about buying a metalworking machine almost always revolves around the price of the equipment. And half of the projects that get delayed aren't delayed because of the equipment: they're delayed because of the room.

This is a list of what you should have sorted out before signing, not after. The specific figures for each model are in its data sheet; here's what you need to look at and why.

The path to the site

First and foremost, and surprisingly enough, the first thing to do is measure the doorway. An industrial LPBF machine doesn't always fit through a standard doorway, and discovering this on delivery day means a crane, a disassembled window, or a return.

The entire route needs to be checked: street entrance, hallways, turns, elevator if there is one, and headroom. The ALBA 300 is specifically designed to avoid all of that—it enters through a standard door—and this difference is only noticeable after you've encountered the problem.

The soil and the site

Load capacity. Hundreds of kilos concentrated in a small area.
Leveling. A machine that spreads powder layer by layer needs to be perfectly level.
Vibrations. Unpleasant neighbors: a press, an overhead crane passing overhead, a forklift unloading nearby.
Space around, not just underneath. It needs to be possible to open it, remove the tank, change filters, and allow a technician access. The service opening is just as essential as the machine itself.

Current

Two questions: what voltage and how much power. The second one matters more than it seems, because you have to add up the machine, the post-processing ovens, the compressor and the air conditioning, and check that the panel can handle it.

This is another point where a machine that operates on 230V single-phase changes the project: it goes from "an installation is needed" to "it just plugs in." It's advisable to check this before assuming that construction work is required.

Inert gas

The build chamber operates in a controlled atmosphere, usually argon, and a decision must be made about how it is delivered:

Option	When it fits
Bottles	Low or irregular consumption. Less investment, more handling
Bottle bank with ramp	The usual middle ground
Cryogenic tank	High and stable consumption. Cheap per kilo, and a proper installation

And one thing that cannot be forgotten: argon displaces oxygen. A room with inert gas requires adequate ventilation and, depending on the installation and local regulations, oxygen detection. It's not optional and it's not expensive; it's just something that's forgotten.

Extraction, filters and condensate

The process generates metallic fumes and condensate, which are removed by the circuit using filters that need to be changed. Two practical consequences:

A procedure and a designated area are needed for changing filters and managing the waste, which is hazardous waste in reactive alloys.
Used filters cannot be stored just anywhere or thrown in the trash.

The powder zone

It's the most underestimated aspect, yet it's the one that most significantly alters daily routines. Handling fine metal powder requires its own dedicated space:

Separate surface for loading, unloading, sieving, and storing.
Screening machine, if you want to reuse the powder properly. This is what Garbi does, in a closed circuit and without the operator inhaling any fumes.
Dedicated powder extraction — not a shop floor vacuum cleaner, which is dangerous with fine and reactive powders.
Storage in a closed, dry, and clearly marked area.
With reactive alloys —titanium, aluminium—, all of the above falls under ATEX regulations. This is explained in ATEX and reactive powders.

Atmosphere

Stable temperature and humidity. Humidity spoils the powder, and spoiled powder spoils the parts.
Cleanliness. A cleanroom isn't necessary; what's needed is that no grinding powder falls into the tank.
The machine heats the room. If the shop floor is already operating during the summer, keep this in mind.

Post-processing: what's almost never on the list

An LPBF machine alone does not produce parts. To have a finished part, at least the following are required:

Stress relief oven, which is often the first purchase forgotten.
Wire saw or EDM machine to separate the part from the platform.
Tool and workbench to remove supports.
Access to machining for the functional faces.

It is developed in post-processing, and is the reason why the start-up kits of the store(/store/ exist: the problem for the beginner is not the machine, it is everything around it, and he discovers it after buying.

People

The final step, and the one that determines whether the project works, is to require someone responsible for the machine, who is trained, and preferably two people so that vacations don't halt production. An LPBF machine without a clear owner ends up being used at only 20% capacity.

The shortlist to take to the meeting

Does it fit through the door and reach its designated location?
Is the floor stable, level, and vibration-free?
What voltage and power can the panel with the ovens and compressor handle?
How is the argon supplied, and is there adequate ventilation and oxygen detection?
Where are the filters changed, and where is the waste disposed of?
Where is the powder handled and stored? Is ATEX certification required?
Are the temperature, humidity, and cleanliness acceptable?
Are there ovens, cutting equipment, and machining access points?
Who is responsible, and who is their backup?

If you want to review it with someone who has done the installation before, write to us or bring the part to an open day and we'll discuss it with the machine in front of us.

What is needed for the gas line and why is oxygen detection needed in the room, in argon or nitrogen.
