How to write a spec that gets priced correctly

A drawing is a contract. If it leaves a number open, the shop fills that number in with its own default. The default is rarely the one you had in mind. Put these five lines on every RFQ and most of the back-and-forth disappears before it starts.

• A model and a drawing that agree
• Material by standard number
• Tolerance only where it mates
• Finish and the faces it applies to
• Quantity and required date

The point is not paperwork. Each line removes a decision the shop would otherwise make for you. A complete RFQ comes back priced. An incomplete one comes back guessed.

What actually drives the price

Buyers usually push on material because it is the line they can see. In practice the material is rarely the biggest number on a quote. These five lines decide most of it:

• process choice
• material
• tolerance band
• finish
• volume

Ask for the quote split by line. A supplier who cannot break it down is guessing, and you will pay for the guess. The line you can usually renegotiate is the tolerance band, not the raw material.

Problems you will meet, and the fix

Every process has a failure mode it prefers. The same four show up again and again on this kind of work, and none of them are mysteries once you know what to look for.

• A drawing that contradicts the model
• A tolerance with no datum
• A cosmetic callout with no approved sample
• A quote compared against a different scope

Catch the fault on the first part, not the hundredth. A first-article check costs an hour. A bad batch costs the whole order. Write the check into the purchase order so nobody has to remember it.

What to check on the first article

The first article is the cheapest inspection you will ever buy. Use it properly and the rest of the run becomes boring, which is exactly what you want.

• Every dimension on the drawing, with the measured value written beside it.
• The material certificate, matched to the heat or lot number on the parts.
• The finish against the sample you approved, under the same light.
• Fit against the mating part, assembled rather than measured.
• Packaging, because parts that arrive damaged were never in tolerance.

Check in this order: datums, then mating features, then cosmetic faces. If the datums are wrong, every number after them is noise. Keep the report on file. When a problem shows up in month six, that document is the only thing that tells you what changed.

How to compare two quotes fairly

Two numbers are not comparable unless the scope matches. Line them up before you decide, because a low number with three gaps is not a low number.

Same drawing, same material, same finish, same inspection. Anything else is a different job wearing the same part number. Then look at what each quote leaves out. Freight, packaging, certificates and tooling are the usual gaps.

Ask each supplier to state their assumptions in writing. The one who does is usually the one who has run the process before.

Scaling from one part to a batch

The first part teaches you the process. The hundredth teaches you the process cost.

Watch three things as volume grows: setup amortisation, tool wear, and how much hand work the finish still needs. If the unit price barely moves between ten and a hundred, the cost sits in material or in hand work, not in setup. Ask which, because only one of them is negotiable.

Lead time behaves the same way. A one-off is scheduled around other jobs. A repeat order is scheduled around your forecast. Give the shop a forecast and the lead time gets shorter, not longer.

How to read a supplier's quote

A quote is a short document with a long shadow. Four things in it decide whether the job runs smoothly, and only one of them is the price.

• The scope line. It should name the process, the material and the finish, not just the part.
• The tolerance basis. General tolerance or the drawing, and which standard it follows.
• The exclusions. Tooling, freight, certificates and inspection are the usual omissions.
• The validity date. Material prices move, and an open-ended quote is a promise nobody can keep.

Read the exclusions before you read the total. A quote that leaves out tooling is not cheaper. It is a quote for a different job.

What to send with the first order

The first order sets the pattern for every order after it. Send a complete package once and the shop files it, and the second order takes a fraction of the time.

• A STEP or native model plus a PDF drawing carrying the same revision letter.
• The material callout by standard number, not by trade name.
• The finish and the exact faces it applies to.
• Any test the part must pass: fit, seal, drop, salt spray, dielectric.
• A contact who can answer a question inside one working day.

Then write down what was agreed. An email that confirms the material, the finish and the date is worth more than a longer purchase order that leaves them open.

When this is the wrong choice

A good supplier tells you when the process does not fit. These are the cases where we say so.

• The volume is so low that setup costs more than the parts are worth.
• The tolerance is tighter than the process can hold without a second operation.
• The geometry cannot be made without a tool feature that will not pay back.
• The material you need is not available in the form the process requires.
• The schedule is shorter than the tooling or setup time, and nobody has said so yet.

None of these are refusals. They are reasons to look at a different route, and the earlier that conversation happens the cheaper it is. The most expensive mistake in manufacturing is a process chosen before the question was understood.

Planning the ramp from prototype to production

The gap between one good part and a thousand identical ones is a plan, not a machine. Three decisions close it.

First, freeze the design. Every change after tooling starts is a re-cut, and re-cuts are where schedules go. Second, decide the inspection level. A prototype is checked by eye; a production part is checked against a report. Third, agree the change process in writing, including who pays for it.

Write the ramp down as dates and owners, not as intentions. A ramp plan with three names and three dates is worth more than a page of good intentions.

What documentation to expect

Paperwork is not bureaucracy when a part fails at the customer. It is the only record of what was agreed. A normal shipment should carry four documents.

• A dimensional report covering every callout on the drawing.
• A material certificate traceable to the heat or lot number.
• A finish or coating certificate where the specification requires one.
• A packing list that matches the carton labels.

If a supplier cannot produce these on request, they are not running a controlled process. Ask for one sample set before you place the first order and you will know exactly what you are buying.

How to handle a change after the order

Changes happen. What matters is whether the change is priced, scheduled and recorded, or absorbed quietly and discovered later.

Send the change as a new revision, not as a note in an email. Ask for three answers in writing: what it costs, what it does to the date, and what happens to material or tooling already committed. Then decide.

A change without a revision number is a rumour. The shop will build what it has on file, and both sides will be right and unhappy at the same time.

How the work actually runs, step by step

Most buyers see two numbers: a price and a date. Between them sits a sequence that decides both. On manufacturing work it looks like this.

1. File review. The model and the drawing are checked against each other. Where they disagree, the shop stops and asks, because guessing is how scrap gets made.
2. DFM feedback. The features that add cost and the features that will not hold tolerance are listed. This is the cheapest hour in the whole project.
3. Setup or tooling. Fixtures, programs or a tool are built. Everything downstream inherits the quality of this step.
4. First article. One part is made and measured against the drawing before anything else runs. Nothing is signed until it passes.
5. Production. The run goes ahead with the parameters that produced the approved first article, not with new ones.
6. Inspection and packing. The callouts are measured, the certificate is matched, and the parts are packed so they arrive in the condition they left in.

Ask any supplier to walk you through these six steps on your part. The answers tell you more about the shop than the price does.

How it compares with the alternatives

No process wins everywhere. The honest comparison is against the two routes you would otherwise take, and the answer usually turns on volume, tolerance and how much the tooling costs.

• Low volume, simple geometry: a faster process usually wins, because setup dominates the price and there is no tool to amortise.
• High volume, stable design: the dedicated process wins, because cycle time replaces labour and the tool cost spreads thin.
• Tight tolerance on a few faces: add a finishing operation rather than paying for a tighter process everywhere.
• One-off repair or legacy part: a digital route is often the only one that makes economic sense.

Decide with the crossover volume, not with a preference. Ask each supplier where their process stops being competitive, and you will usually get a straight answer.

What a good finished part looks like

Quality is not a certificate on the wall. It is a set of things you can see and measure on the part in your hand, and they are the same on the first unit and the five-hundredth.

• Clean edges. No burr that will cut the person packing the box, no dross left on a cut face.
• Even finish. The same colour and texture across the whole surface, with no drift between batches.
• Straight geometry. A part that sits flat on a surface plate without rocking, and that measures the same on two different days.
• Correct fit. It assembles against its mating part with hand pressure, not with a press and not with a file.
• Traceable paperwork. A report that matches the parts in the box, with the heat or lot number on both.

None of these require a laboratory. They require a shop that checks the first part properly and then keeps the process still. If the fifth part looks different from the first, the process moved and nobody noticed.

Materials Used in Our Medical 3D Printing

The choice of material is critical to the success of medical 3D-printed products. We only use materials that meet biocompatibility, sterility, and durability standards:​

Our solution for Medical 3D Printing Services

YiguProto runs custom manufacturing in house, from a single prototype to a production batch. We quote the process, the material and the finish as separate lines, so you can see where the money goes instead of arguing with one number.

Send a STEP file or a drawing and you get a DFM report in one to two business days. It flags the features that add cost and the features that will not hold tolerance on the process you picked.

Every order ships with an inspection report on the features you call out. If a part misses, we make it again. Ready to price a part? Start with a free quote and DFM review, or read more about our custom manufacturing. You can also talk to an engineer before you commit to a drawing.
