Common Mistakes and Notes
Who This Checklist Is For
I'm a quality and brand compliance manager at a custom manufacturing company. I review every incoming job package before it reaches customers—roughly 200 items a year. In 2024, I rejected about 18% of first deliveries because the spec didn't match what was quoted. Not because the vendors were careless. Because we weren't asking the right questions.
This checklist is for manufacturing engineers, R&D teams, and production managers comparing a desktop-metal system, a desktop CNC machine for metal, or a mixed additive/subtractive workflow. It's also for anyone watching additive manufacturing industry trends 2025 and trying to separate real production capability from trade-show demos. Eight steps. Follow them before you sign.
The 8-Step Checklist
Step 1: Define the acceptance spec, not the machine category.
Start with the part. What's the tolerance? Surface finish? Wall thickness? Load? If you say 'metal bracket,' you'll get three vendors talking about different things.
I said 'production-ready surface finish.' They heard 'as-sintered is fine.' Result: 40 parts went to secondary finishing and blew the timeline. Now every RFQ includes a one-page acceptance spec with numbers, photos, and a sample part. No numbers, no quote.
Step 2: Separate Desktop Metal Production System Price from Total Cost of Ownership
Desktop Metal production system price is rarely a single number. As of January 2025, Desktop Metal's public product pages list the Production System P-50 as quote-based, not a fixed list price. Verify current terms with the vendor. The quote should include binder, metal powder, sintering, service, installation, training, and consumables. If it doesn't, it's not a price. It's a starting point.
I've learned to ask 'what's NOT included' before 'what's the price.'
Compare total cost per good part, not cost per machine. A lower upfront number with hidden sintering fees isn't cheaper. It's deferred cost.
Step 3: Match Material to Process—Not the Other Way Around
What materials are used in additive manufacturing? For metal binder jetting, common powders include 316L stainless steel, 17-4 PH, copper, and tool steel. Laser powder bed systems use similar metals plus titanium and aluminum alloys. But availability isn't qualification. Ask for material datasheets, lot traceability, and sintered properties.
Per ISO/ASTM 52900:2021, terminology matters—but your acceptance test matters more. For Desktop Metal, confirm which materials are qualified on the exact system. Not on a predecessor. Not on a demo unit. The exact system you'll run.
Step 4: Treat Post-Processing as a First-Class Process
Additive doesn't mean no post-processing. It means different post-processing. Depowdering, sintering, support removal, machining, surface finish, heat treat. If a vendor says 'no post-processing at all,' walk. The part won't meet most production specs.
Build those steps into the quote and lead time. Otherwise you'll discover them during the first production run, when the line is already waiting.
Step 5: Evaluate a Desktop CNC Machine for Metal with the Same Rigor
If your workflow needs subtractive finishing, a desktop CNC machine for metal should be judged on rigidity, spindle power, coolant, thermal stability, tooling, and work envelope. Desktop doesn't mean toy. It also doesn't mean it replaces a full-size VMC for every part. It's a different capability.
Ask for test cuts in your material. Measure them. Don't trust a demo in aluminum if you're cutting stainless. The machine that cuts aluminum beautifully can chatter in 316L.
Step 6: Don't Assume Your 4 Axis CNC Wood Lathe Covers Metal Fixturing
A 4 axis CNC wood lathe can be great for fixtures, patterns, or prototypes. But wood dust, workholding, and tolerance expectations are different from metal. If you plan to use it for production fixtures that locate metal parts, verify flatness, repeatability, and thermal drift. The fixture becomes part of your quality system.
When I compared a wood-lathe fixture against a machined metal fixture side by side, I finally understood why the cheaper fixture was costing us setup time on every run. Not a huge amount. Enough to matter over 200 runs.
Step 7: Ask for a Transparent Quote—Line by Line
Here's the thing: most surprises show up as line items that weren't on the first quote. Setup. Rush. Material lot minimums. Sintering batch fees. Calibration. Requalification. Packaging. Ask for a line-item quote with assumptions and exclusions.
If a vendor won't show exclusions, that's your answer. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. I'd rather approve a complete quote than defend a surprise invoice.
Step 8: Run a Blind A/B Test Before Scaling
Take the same part, same material, same spec. Run it on the Desktop Metal system and the desktop CNC machine for metal, or on two vendor quotes. Don't label the parts. Have your quality team and a customer-facing engineer inspect them.
In 2024, we did this with 50 brackets. The cheaper process passed dimensional checks but failed surface finish on 12% of parts. We caught it before the 5,000-unit run. Why does this matter? Because additive manufacturing industry trends 2025 point toward production, not prototyping. Production punishes assumptions.
Common Mistakes and Notes
Mistake 1: Comparing machine price to part price. They're different numbers.
Mistake 2: Treating material availability as material qualification. A datasheet isn't a process window.
Mistake 3: Skipping the handoff language. I said 'ASAP.' They heard 'whenever convenient.' Result: delivery two weeks late. Now we write dates, quantities, and acceptance criteria in the same email thread.
Mistake 4: Assuming Desktop Metal, CNC, or a 4 axis CNC wood lathe replaces the other. They don't. They solve different constraints. The quality plan should connect them, not pretend they're interchangeable.
If you only do one thing: ask for the total cost per good part, with exclusions in writing. That single question will filter more bad deals than any demo. (Note to self: add the exclusions checklist to our standard RFQ template. I really should do that this quarter.)
