  Metal 3d printer cost vs CNC machining: which fits

Metal 3d printer cost is not one number. It is the sum of five decisions: process type, build envelope, laser or electron beam count, material system, and the support equipment you need to run the machine safely. Get any one of them wrong and the quote you receive will not match the work you actually have.

Process type sets the floor. Bound-metal and metal extrusion systems use debinding and sintering furnaces, so the printer is only part of the cell. Laser powder bed fusion (LPBF) and electron beam melting (EBM) skip the furnace for most alloys but need powder handling, sieving, and inert gas.

Build envelope sets the ceiling. A 100 mm cube machine and a 400 mm cube machine differ by far more than the frame size. Bigger envelopes need bigger lasers, more powder per job, and longer cool-down, which pushes both capital and running cost up.

Laser count is the throughput lever. One 200 W laser is slow on thick sections. Two or four lasers cut build time, but they add cost, calibration work, and more complex scan strategies. Buy laser count for the parts you run, not for the brochure number.

It helps to sort machines by what they actually produce rather than by brand. Small bound-metal systems with a 150-200 mm envelope are often bought for tooling inserts, small brackets, and low-volume stainless parts. They are compact, but the furnace is a separate cost, and shrinkage control on long thin parts takes practice.

Mid-size LPBF machines with a 250 mm envelope and a single 400 W laser are the workhorse class for functional prototypes and small production runs. They handle 316L, 17-4PH, and AlSi10Mg well. If your part fits in a 250 mm cube and the wall is above 0.4 mm, this class will usually do the job.

Large multi-laser LPBF machines with a 400 mm envelope and two to four 500-700 W lasers are aimed at aerospace ducts, heat exchangers, and medical implants at volume. The cost jump is not linear. You are paying for laser optics, faster recoating, and the gas flow design that keeps spatter off the part.

EBM machines use an electron beam in vacuum and run hotter. They suit titanium orthopedics and parts where residual stress matters more than surface finish. The trade-off is rougher as-built surfaces, so expect more post-machining on critical faces.

Powder is the largest recurring cost on most machines. Stainless and aluminum powder sit at the low end. Titanium, Inconel, and cobalt-chrome powders cost several times more, and you cannot reuse all of it. Each build cycle degrades the powder slightly, so shops blend virgin powder back in at a set ratio.

Inert gas matters on LPBF. Argon consumption depends on chamber size, leak rate, and how often you open the door. A small machine with tight seals can run far cheaper per hour than a large chamber that is opened twice a day. Budget gas as an hourly cost, not a yearly guess.

Post-processing is where estimates usually break. As-built LPBF surfaces sit around Ra 8-12 μm. If the print needs a sealing face, a bearing bore, or a thread, you are adding CNC time, and that time is often more than the printing time. Support removal, stress relief, and HIP add further steps.

Consumables age out. Lenses, recoater blades, filters, and nozzles are replaced on a schedule. Those parts are not expensive individually, but they add up. A realistic running budget should include a spare parts line of 5-10% of the machine payment each year.

A machine only pays back if you keep it busy. Metal AM needs regular builds to stay calibrated and to justify the powder inventory. If your parts arrive in bursts of two or three a month, the machine will sit idle while the payment continues, and the powder in the hopper will age.

Geometry decides more than volume. A part with internal channels, lattice structures, or organic ribs is a good AM candidate because no cutter can reach those features. A simple block with a few holes is a bad candidate. It can be milled faster, cheaper, and with a better surface, and the design work for AM would be wasted effort.

Size matters as well. If the part is larger than the build envelope, you either split it and add a joint, or you machine it. A split joint adds a leak path and a cleaning problem inside channels. For most fluid parts, that is a hard no.

There is a middle path. Keep the printer for the features that only AM can make, and send the rest to a CNC shop. Hybrid parts, where an AM preform is finish-machined on the critical faces, are common in aerospace and medical work for exactly this reason.

  Hybrid approachPrint the complex core, machine the critical faces.

Take a 316L bracket that fits in a 100 mm cube. On a small LPBF machine, the build takes roughly 8-12 hours depending on layer height. Powder use is about 1.5-2 kg including supports and the surrounding bed. Post-processing adds support removal and one face milled to a sealing tolerance.

Now put the same bracket on a 3-axis mill. If the design has no internal channels, cycle time is short and the part comes off at Ra 1.6-3.2 μm with no support removal. For a run of 50 pieces, the milled parts usually cost less per piece than the printed ones, and they arrive faster.

Change the design to include a curved internal cooling channel. The mill cannot reach it. Now the printer is the only route, and the cost per part is justified by a feature that does not exist in the milled version. This is the real deciding question, not the machine price.

If you need both, run the hybrid route. Print the channel core, then machine the mating faces and bores. That is how GreatLight handles parts that combine AM features with sealing surfaces, using 5-axis machining for the critical faces after printing.
