What the Job Costs Without the Tool

Our relationship to the hardware
No Unit Here
2 substitutes recorded
Every machine page is a comparison against this one. A tool is worth owning only relative to what the same job costs from somebody who already owns it, and that figure is missing from almost everything written about buying tools, because almost everything written about buying tools is funded by selling them.
The substitutes the assessments record
Read from the assessments themselves. Where a tool can be avoided, this is what avoiding it costs. The figures on this page are computed across 3 example assessments, written to test the model rather than chosen as a sample. They show the calculation, not a result.
Freezer Temperature AlarmSoldering Iron and Multimeter
Buy the pre-soldered board variant and the probe with the resistor already fitted.
- US
- $0
- UK
- £0.70
Or borrow itMost makerspaces have one, and many public libraries now do too.
Letterbox Post SensorBasic Power Tools
Only needed for a metal letterbox, where the aerial has to sit outside the box. A plastic or wooden box needs no drilling at all.
- US
- $0
- UK
- £0
Or borrow itA drill is the most commonly borrowed tool there is.
What that adds up to
The cheapest substitute on the site is 70p, and it removes an entire skill. Buying the freezer board with its headers already soldered and the probe with its resistor fitted takes soldering out of that build completely, for less than the cost of the solder. The other one costs nothing at all: the letterbox sensor only needs a drill if the letterbox is metal, and a plastic or wooden one needs no drilling.
Neither of those is a machine you buy. Both are a different version of the same part. That is the commonest substitute in this category and it is the one no printer comparison mentions.
Where there is no substitute
The soldering on the letterbox sensor is not avoidable by buying a different part, because the assembly is bespoke. It is still borrowable, and the assessment says where.
Printed parts
A retrofit sensor generally needs a housing, so this is the substitute most of these projects will eventually meet: what a small enclosure costs from a bureau when you own no printer. None of the examples above reaches it yet, and the figures are priced against a typical 30cm³ part rather than against a specific one.
The table scrolls sideways to the figures.
| Route | What you get | One part, US $ | One part, UK £ | Source |
|---|---|---|---|---|
| Bureau with no minimum | Posted to you, a few days. | 8 to 25 | 12 to 18 | S3, S4 |
| Bureau with a minimum order | Same part, same days. You pay the floor whether you use it or not. | 25 to 150 | 50 | S1, S2, S3, S4 |
| Setup fee, where charged | Once per model, not per copy. Second copy is cheap; second design is not. | 3 to 10 | 10 | S1, S4 |
The finding, in both markets
The minimum order decides whether a bureau beats a machine, and it is not visible until checkout. In the US the floor runs from nothing at all, through $25 at two large bureaus, to $150 at a third. In the UK it runs from nothing to £50 plus £10 a model. The same single part costs six times as much at one end of either market as at the other, and no price on that range is wrong: the ones with floors charge setup per model rather than per copy, so they are priced for batches rather than expensive.
One distinction is worth carrying, because most comparisons miss it: no minimum quantity is not the same as no minimum charge. A bureau will happily take an order for one part and still bill you $25 for it.
Six bureaus, four US and two UK, classified as use-case mismatch rather than resolved. Six is enough to show the split is structural rather than local and not enough to say what share of either market sits at each end. These are the bureaus that publish their terms, which is not a sample of anything.
When the substitute is the wrong answer
Not on this page
- Makerspace membership, which is how the shared-access route is actually priced and is a different comparison from paying per part.
- What share of bureaus in either market charge a minimum. Six published terms show the split exists; they do not weigh it.
- Laser cutting and CNC services, which the same argument applies to.
- Shipping, charged on top of every bureau figure above.
- Public libraries. Removed rather than deferred, on two grounds that hold whatever gets assessed: coverage is unknown, and the material on offer is PLA, which is brittle in the cold and degrades outdoors. A route that cannot make the part is not a substitute for making it.
Sources
Four, all vendor documentation, which is the lowest weight the method recognises. A vendor is authoritative about its own prices and about nothing else. The substitutes in the first section are not sourced here: they come from the assessments, and their sources are on those pages.
S1Shapeways, "Why is a surcharge added to my order?"
Vendor Documentation
US bureau, USD 25 minimum order excluding shipping and handling. An order below it is surcharged up to 25 rather than refused.
Read from a search summary: the support page returns 403 to an automated fetch, so it is unverified at source and flagged for the link checker.
Vendor Documentation
US-facing bureau, no minimum quantity - one part is fine - but a USD 25 minimum order value excluding shipping.
States the two rules separately, which is the distinction most comparisons miss: no minimum quantity is not the same as no minimum charge.
