Buy a Brother Speedio or Just Outsource? An Admin Buyer’s Honest Comparison of a VMC vs. ProtoLabs

Why I compared a Brother Speedio machining center with ProtoLabs

Last fall, our engineering manager dropped a product sheet for a Brother Speedio machining center on my desk. “If we do a VMC installation here,” he said, “we stop paying outside vendors for prototype lead times.” He wasn’t wrong about the lead times. The Speedio is a genuinely fast machine, and for small aluminum and steel parts it earns its reputation.

What he was missing was the difference between buying a machine and becoming a machine shop.

I’m not an engineer. I’m the office administrator who runs purchasing for a 40-person product development company. That means I process 60-80 orders a year, manage roughly 10 active vendors, and look after about $400,000 of annual manufacturing spend. My job is not to design parts. It’s to make sure they show up, meet the spec, and arrive with an invoice finance can actually process.

So when the “buy versus outsource” debate started, I did what I do with every big purchase: I asked for quotes. We got a VMC installation price from a local integrator, and I uploaded the same part files to ProtoLabs on the same day. Comparing those two documents taught me more than the machine brochure ever did.

Here is the framework I’d use if you’re facing the same decision: compare cost, speed, the skills required to run the equipment, and the range of processes you actually need.

Comparison No. 1: what a machine really costs before it cuts its first chip

The brochure quote for the Brother Speedio machining center looked reasonable. The machine itself was not the problem. The problem was every line item that appeared after it on the VMC installation quote.

Installation alone meant site prep, rigging, 3-phase power, air supply, coolant and chip handling, plus the better part of a day for calibration. Then came the tooling list: vises, toolholders, end mills, edge finders, a presetter if you’re smart, and CAM software with a postprocessor. Add material stock, workholding, and insurance, and a machine that starts as a six-figure capital item ends up consuming a lot more before a single good part exists.

The ProtoLabs quote was structured differently. We selected a material, a finish, a quantity, and paid for what we asked for. For the machined parts, there was a small setup charge. For the 3D-printed parts, there was no tooling cost at all. That was it. No depreciation on a machine sitting idle, no tooling cabinet to fill, no surprise expense when the spindle needed maintenance.

The mistake I see in most buy-versus-outsource math is comparing the machine’s hourly running cost to a vendor’s price per part. That comparison ignores the fact that a machine you own bills you whether it runs or not. An idle machine in your building is not an asset; it’s a monthly reminder that you bought a fixed cost. A vendor’s price at least includes the reality that their equipment is being used by somebody.

The conclusion on cost: for a company like ours, where part designs change often and no single part runs for weeks at a time, the on-demand route was dramatically cheaper. If your team can genuinely keep a VMC loaded for most of a working week, repeat the same jobs, and already have a machinist on staff, the math changes. I don’t think it changed for us.

Comparison No. 2: “in-house” isn’t automatically fast

The most persuasive argument for buying a machining center was speed. “Once it’s here, we can make parts in hours instead of waiting days.” That statement has one flaw: the machine is not instant, and neither is the person running it.

After you order a Brother Speedio, you wait for delivery. Then you wait for installation. Then somebody has to program the part, set up the workholding, run a test piece, and inspect it. For a company that doesn’t already do CNC work, that is not a one-day process. It is a project with a schedule, a learning curve, and a first-article inspection that still might fail.

Meanwhile, the ProtoLabs order moved at a pace that felt almost strange in manufacturing. We uploaded the parts and received a manufacturability review with the quote. We approved it. The machined parts arrived within about a week, and the 3D-printed parts arrived even faster.

I should be fair here: in-house equipment does have a real speed advantage once it is already running and already set up for your recurring job. If you make the same bracket every week, a VMC will beat any external supplier on lead time. But that advantage assumes a fully staffed, running machine shop. We were not that. We were a design company with a romantic idea about owning a machine.

One small example: an engineer found ProtoLabs by searching “ProtoLabs drone 3D printer.” The phrase made me pause, because ProtoLabs doesn’t sell 3D printers. It runs them. We uploaded a drone payload bracket as a CAD file, and the printed part came back in a few days—without us owning any printer, filament, or failed first layer.

The conclusion on speed: if you need a part this week, an on-demand digital manufacturer is usually faster than buying and installing a VMC. If you already have the machine running and the operator standing there, in-house wins. Those are two different situations, and it’s worth being honest about which one you’re really in.

Comparison No. 3: the machine is the easy part; the skills are harder

Here is the thing nobody puts in the brochure: a machining center does not make parts. A machinist makes parts. The machine just moves the tool.

Our company has design engineers, electronics engineers, and test technicians. We do not have a CAM programmer. We do not have a toolmaker. Hiring one person for a VMC would add salary, benefits, training, and risk. And even then, one machinist cannot run a machine 40 hours a week and also handle the production planning, tooling inventory, and quality paperwork that come with real machine shop work.

Using ProtoLabs meant we bought access to a team that runs these processes daily. When we uploaded the CAD files, the automated review flagged a wall thickness that was too thin and a threaded hole placed too close to an edge. We got that feedback before spending money, not after receiving bad parts.

I have mixed feelings about giving up direct control. Part of me likes the idea of walking over to a machine and making adjustments ourselves. That level of control is valuable when you already know what you’re doing. For a company that doesn’t, control is not a benefit. It’s just a longer, more expensive way to learn the same lessons.

The conclusion on skills: if you already have an experienced machinist or a real manufacturing engineer on the team, buying a VMC is a reasonable decision. If you don’t, the machine becomes an expensive training program. We chose to rent expertise instead of trying to hire it.

Comparison No. 4: one process versus a full menu

A Brother Speedio machining center is excellent at one thing: milling. It cuts metal and plastic precisely, and it does it fast. But it cannot 3D-print an internal lattice, it cannot injection-mold a production run, and it cannot laser-cut a sheet of plywood in the same afternoon.

Let me answer that last question directly, because I typed it into a search engine myself when we needed a wooden fixture: yes, a laser cutter can cut plywood. A typical CO2 laser will handle thin birch plywood up to about 1/4 inch reasonably cleanly. The cut edge will be darker than a CNC router edge, which surprises some people. You also need proper exhaust, and you should avoid construction-grade plywood because the glue line fumes are genuinely unpleasant. But the short answer is yes—a laser cutter cuts plywood.

The broader point is that a single machine is a single process. ProtoLabs offered us CNC machining, 3D printing, and injection molding through the same digital workflow. When the drone bracket worked as a 3D-printed prototype, we got a CNC-machined version for the real tests. When one of our products finally needed higher volumes, I looked up ProtoLabs injection molding contact email, expecting to have to convince a human to take us seriously.

Instead, we uploaded the production part model and got a quote that included both the tooling cost and the per-unit price. I didn’t need to send an email at all. That process was a sharper contrast to the VMC route than I expected.

The conclusion on process range: if your company makes thousands of the same machined part year after year, a dedicated VMC is a legitimate choice. If your roadmap includes prototypes, functional test parts, low-volume production, and a few material changes along the way, you don’t want one machine. You want a supplier with a menu.

So do we install a VMC, or keep ordering from ProtoLabs?

We did not buy the Brother Speedio. As of January 2025, we are still ordering through ProtoLabs and keeping a small list of local machine shops for jobs that are better handled by someone down the road. The VMC installation conversation is not closed forever, though.

I would seriously consider buying a machining center if these things are true: we have a machinist or a clear plan to hire one, the part mix is stable enough to keep the spindle busy, and we need tight control over proprietary work or frequent design iterations that happen at the machine. A company that already runs a machine shop has a different calculation than a product development firm.

I would choose the on-demand route if the team is mostly designers, if part quantities change regularly, and if the real bottleneck is not machining but the ideas being tested. For us, the cost of owning a VMC was not just the machine. It was the people, the training, the tooling, and the time spent learning a craft we don’t need to be good at.

A Brother Speedio machining center is a fine piece of equipment. The mistake would have been confusing the machine with the capability. The machine cuts metal when someone starts it. The capability is the people, process, and knowledge behind it. For now, we would rather rent that capability than try to own it.
