How I Consolidated 8 Vendors into One Platform (and What I Learned in the Process)

When I took over purchasing for my company in 2020, I inherited a mess. We were a 50-person engineering consultancy, and our prototyping and low-volume production needs were spread across eight different vendors. We had a guy for 3D printing, another for CNC, a separate shop for laser cutting, and a specialist for injection molding. I spent my first six months just figuring out who did what.

The Straw That Broke the Camel's Back

It was a Thursday afternoon in late 2022. Our lead engineer needed a rush order of 30 custom-machined aluminum brackets. I sent the CAD file to our usual CNC shop. They quoted me $1,800 with a 3-week lead time.

Three weeks was too long. I called a different shop. They could do it in 10 days for $2,400. I went with the first shop, hoping they'd deliver early. They didn't.

The brackets arrived on day 21. They were the wrong size. Seriously. The engineer had updated the file the day after I sent it, and I had forgotten to forward the revision. The shop used the old drawing.

I had to eat the cost—$1,800—and explain to my manager why our project was delayed by another two weeks. That was the moment I knew we needed a change.

Why I Decided to Try a Unified Platform

I had heard about platforms like Shapeways that offered multiple manufacturing processes under one roof. The idea of a single quote, a single order, and a single delivery was appealing. But I was skeptical.

I went back and forth for about a month. A unified platform meant less flexibility, right? I might lose the personal relationships I had built with my individual vendors. But the alternative—more errors, more delays, more hidden costs—was worse.

The First Order on Shapeways

I decided to test it with a small, non-critical project: 50 3D-printed prototype enclosures. The process was, to be honest, surprisingly smooth. I uploaded the STL file, got an instant quote (around $12 per part), and selected a material. That was it. No back-and-forth emails. No phone tag.

The parts arrived in 5 business days. They looked decent. More importantly, the billing was clean—one invoice, one line item. Our accounting team loved it.

The Unexpected Twist (There's Always One)

Feeling confident, I placed a larger order: a batch of laser-cut acrylic panels for a trade show display. This time, I needed a material that Shapeways didn't list clearly on their website. I had a ton of trouble figuring out which acrylic grade to choose.

I called their support. The agent was helpful but admitted, "We don't have hard data on the exact flexural strength for all our acrylic grades. Based on our experience, Grade X is what most customers use for trade show displays."

That honesty was refreshing. I went with Grade X. The panels arrived, and they worked perfectly. But the hesitation I felt made me realize something: I needed to verify material specs upfront, even on a unified platform.

Now, before ordering any material I'm not 100% familiar with, I request a sample or a spec sheet. It's an extra step, but it's saved me from potential disasters. 5 minutes of verification beats 5 days of correction.

Three Things I Learned (The Hard Way)

Looking back, here's what I took away from this transition:

• Check your file versions. Sounds obvious, but I can't tell you how many times I've seen engineers send outdated files. On Shapeways, you can add revision notes in the order, which helps.
• Ask about process limits. Not all platforms handle all geometries. For instance, I once needed a part with a very sharp internal corner that couldn't be done with a standard CNC mill. Shapeways' support pointed me to their sintered metal option. I wish I had asked earlier.
• Don't assume 'one platform' means 'no more thinking.' It's easier, sure. But you still need to do your homework.

Did It Solve My Problem?

Mostly. I now use two vendors instead of eight. Shapeways handles about 70% of our orders—mostly 3D printing, CNC machining, and laser cutting. I still use a specialized local shop for very large sheet metal runs (over 500 units), because their pricing is way more competitive for volume.

But the chaos is gone. My internal clients (the engineers) are happier because turnaround times are predictable. Finance is happier because the invoices are clean. And I'm happier because I'm not constantly firefighting.

I wish I had tracked the exact time savings more carefully. What I can say anecdotally is that I used to spend about 6 hours a week on vendor management. Now it's maybe 2 hours. That's a fair bit of time I've gotten back.

A Quick Note on a Specific Order

I also once ordered a batch of personalized gifts—laser-cut leather keychains—for a client appreciation event. A colleague asked, "Can you cut leather with a laser cutter?" I had to check the material guide. Turns out, yes, but you need a leather-specific setting to avoid burning. Shapeways had it as a pre-configured option. That small detail saved me a ton of research.

And for a specific project, I needed a quote for a Chinese 2D laser cutting machine. I wasn't buying the machine, but I needed to understand the spec for a patent we were filing (something about fiber laser doped core patents). Shapeways' DFM team helped me clarify the process limitations, which was super useful for the legal documentation.

The Bottom Line

What started as a cost-cutting exercise turned into a quality-of-life improvement. The unified platform isn't perfect—nothing is. But it removed the single biggest headache in my job: coordinating multiple supply chains with inconsistent quality and communication.

If you're managing vendor relationships for your organization, and you're spending more time fixing problems than planning ahead, it might be worth looking at a multi-process platform. Just do your upfront checks. Trust me on this one.
