Low-Cost 3D Printing Services: Where the Price Comes From
You send the same file to four services and get back $28, $38, $52 and $86. Nobody is lying. They are quoting four different objects, because "print this" is not a specification, and the cheapest quote is usually cheapest for a reason you have not been told yet.
This post takes a single $45 order apart line by line, shows which levers actually move the number, and separates the reasons a service can be legitimately cheap from the reasons a service is cheap because you are about to receive a hollow part.
Why do 3D printing services cost what they do, and where does the money go?
In a typical $45 order for a 100g part, filament is about $2.20 and electricity about $0.35. Labour is roughly 40% of the total, covering setup, removal, support cleanup, inspection and packing, with shipping around $8 and the remainder split between machine wear, failed-print allowance, platform fees and margin.

Key takeaways
- •Filament is about $2.20 for a 100g part at $22 per kilogram. It is almost never the reason a quote is high.
- •Electricity is negligible: an enclosed 150-250W machine over ten hours uses 1.5-2.5 kWh, roughly $0.26-0.43 at the US residential average of about 17 cents per kWh. An open-frame printer averages 70-150W and costs less again.
- •Labour is the dominant cost of any small order, typically 40-50% of the total on a sub-$60 job.
- •The same part quoted at 0.3mm/2 walls/10% infill versus 0.12mm/5 walls/60% infill moves from about $28 to about $86. Specs, not services, explain most price spread.
- •Shipping is roughly $5-12 for a small part and does not shrink with the order, so it dominates the price of anything under $20.
Where the Money Actually Goes
Take a concrete order: a 100 gram functional part in PETG, 0.2mm layers, four walls, 30% infill, printed once and shipped in the US. Quoted at $45. Here is every line inside it.
Inside a $45 order for a 100g printed part
Labour dominates. Filament and electricity together are under $3 of a $45 order, which is why asking a service to use cheaper plastic barely changes your quote.
| line | Cost line |
|---|---|
| Filament | $2.2 |
| Electricity | $0.35 |
| Machine wear | $2.5 |
| Labour | $18 |
| Failed-print allowance | $2.5 |
| Packaging + shipping | $8 |
| Platform fee | $4.5 |
| Maker margin | $6.95 |

Two things fall out of that chart immediately. First, negotiating on material is pointless. Talking a maker down from the top of the PETG price band to the bottom saves a dollar on a 100g part. Second, the number of separate parts matters far more than their total weight, because every part carries its own removal, cleanup and inspection time. A single 200g part is usually cheaper than four 50g parts weighing the same.
If you want to price the material and machine side of your own part, our 3D printing cost calculator does exactly that, and the fuller 3D printing cost guide walks through how the rest of a quote is built.
The Levers That Actually Move the Price
Print time is the real currency. Anything that reduces the hours a machine is occupied reduces your quote, and three settings dominate: layer height, wall count and infill percentage. Here is the same part, same file, same material, quoted at four different spec levels.
Same part, four spec levels, four prices
Going from a coarse draft spec to a fine functional spec roughly triples the quote for identical geometry. If two services quote you very different numbers, ask what layer height and infill they assumed before assuming one of them is overcharging.
| spec | Quoted price |
|---|---|
| 0.3mm, 2 walls, 10% | $28 |
| 0.2mm, 3 walls, 20% | $38 |
| 0.2mm, 4 walls, 40% | $52 |
| 0.12mm, 5 walls, 60% | $86 |

| Lever | Effect on price | When to use it |
|---|---|---|
| Coarser layer height | Large. 0.2mm to 0.3mm cuts print time by about a third. | Any part nobody looks at closely: brackets, inserts, jigs, internal hardware. |
| Lower infill | Moderate. Below about 25% the savings flatten out. | Decorative parts. Not for anything loaded, where wall count matters more anyway. |
| Fewer walls | Moderate, and the most dangerous saving on the list. | Display pieces only. Walls, not infill, carry load in an FDM part. |
| Orientation that avoids supports | Large, and it costs you nothing. | Always. Ask the maker to suggest an orientation. Supports cost material, time and cleanup labour. |
| Flexible deadline | Meaningful. Lets a maker batch your job with others. | Whenever you are not in a hurry. Say "no rush" in the request and mean it. |
| Standard material | Small. PLA versus PETG is under a dollar on a 100g part. | Choose on function, not price. The PLA vs PETG guide covers which is right for what. |
Good Cheap vs Bad Cheap
A low price is not a warning sign by itself. What matters is which cost the service removed. Some of them were never doing anything for you.
Legitimately cheap: a maker with no premises, no sales team and no storefront rent. A print farm batching your job with twenty others. A coarse layer height on a part that does not need a fine one. Generic filament from a reputable supplier. Shipping in a plain box rather than branded packaging. All of these save money that was never buying you anything.
Cheap because they removed something you needed: two perimeters on a structural part. Infill under 10% on anything loaded. Supports left in place because removing them is the slowest job in the process. No dimensional check against your file. No photo before shipping. Unspecified filament of unknown origin, which in practice means inconsistent diameter and unpredictable strength. And, most consequentially, no payment protection, so if the part never arrives you argue about it by email.
The tell is specificity. A cheap quote that states layer height, wall count, infill and material is a real quote. A cheap quote that just states a price is a guess you are being invited to underwrite.
The one thing worth paying for
Photo verification before payment releases. It costs the maker two minutes and it is the only quality control that happens before your money is gone. On our platform funds sit in escrow until you have seen photos of the finished part and approved them, which is a structural fix rather than a promise.
How to Get an Honestly Low Quote
Five things to put in your request. Together they routinely take 30–50% off a quote without changing the part.
Send a print-ready file. An STL or 3MF that is watertight and correctly scaled removes the largest variable-cost line in the whole job.
State the specs yourself. "0.3mm layers, three walls, 20% infill, PLA, no supports if you can orient around it" makes every bid comparable.
Say what the part does. A maker who knows it is a decorative desk piece will not quote it like a load-bearing bracket.
Give a real deadline, and make it generous. Two weeks instead of two days lets the job ride along with other work.
Combine parts into one order. One shipment, one setup, one inspection pass. The $8 shipping line only gets paid once.
Frequently asked questions
Why is 3D printing so expensive when filament is cheap?
Because filament is the smallest line in the quote. A 100g part uses about $2.20 of PETG at $22 per kilogram and about $0.35 of electricity, but it also consumes an hour of somebody time across setup, removal, support cleanup, inspection and packing. Labour is typically 40-50% of a small order total.
What is the cheapest way to get something 3D printed?
Supply a print-ready file, accept a 0.3mm layer height, ask for the lowest wall count and infill the part can tolerate, choose standard PLA, and let the maker batch your job with other work rather than starting it immediately. Those five choices together routinely take 30-50% off a quote without changing the geometry at all.
Is a cheap 3D printing service worth using?
It depends what is making it cheap. A low price from batching, a low layer height, generic filament and a maker with no storefront overhead is fine. A low price from two-wall shells, 5% infill, no support removal and no photo before shipping is a part that will break. Ask which specs the quote assumes.
How much does 3D printing electricity cost per print?
Very little. An open-frame desktop FDM printer averages 70-150 watts while printing; an enclosed machine running PETG or ASA, which is what most service work uses, averages 150-250 watts. A ten-hour print on the latter uses about 1.5-2.5 kWh, so at the US residential average of roughly 17 cents per kWh that is about $0.26-0.43 of electricity for the whole print, which is less than the packaging it ships in.
Why do quotes for the same part vary so much between services?
Because they are quoting different parts. Unless layer height, wall count, infill percentage and material are specified, a $28 quote and a $52 quote can both be honest and describe wildly different objects. Fix the specs in your request and the spread between quotes collapses to something meaningful.
Get Comparable Bids on Your Part
Post the job with your file, your specs and a generous deadline. Makers bid against each other rather than against a fixed price list, and your payment stays in escrow until you have approved photos of the finished part.
