High volume 3D printing: hundreds or thousands of parts
Can 3D printing be used for mass production?
Yes, by splitting the run across several printers. An FDM keyring takes about 11 minutes of machine time: 1,000 is about 179 hours, over 7 days non-stop for a single printer, or about 18 hours each across ten printers. It works out at about €3.44 per unit, excluding VAT and shipping. Fabrishare is a network of makers and print farms: post your project for free and get offers with price and lead time within 24–48 hours.
How many machine hours are 100, 1,000 or 5,000 parts?
Fabrishare calculator estimates, excluding VAT and shipping. Hours are print time on a single machine; each maker sets their own price and lead time in their offer.
| Item | Quantity | Machine hours | Guide price | Per unit |
|---|---|---|---|---|
| Logo keyring, FDM (about 5 × 3 cm) | 1 | 0.3 | €6–€16 | €10 |
| Logo keyring, FDM | 100 | 18 | €350 | €3.50 |
| Logo keyring, FDM | 1,000 | 179 | €3,441 | €3.44 |
| Logo keyring, FDM | 5,000 | 893 | €17,176 | €3.44 |
| 28 mm miniature, resin | 100 | 3.2 | €406 | €4.06 |
| 28 mm miniature, resin | 1,000 | 31 | €3,897 | €3.90 |
In FDM, hours grow with every part: 5,000 keyrings take about 893 hours, over 37 days non-stop on one printer. Split across ten, it's about 89 hours per machine, under 4 days. That's why a large run isn't done by one maker with one printer, but by several makers or a print farm.
In resin, print time depends on height, not on how many parts fit on the plate, so 1,000 miniatures take about 31 machine hours. There the bottleneck is hands: the calculator allows 5 minutes per part to remove, clean and check it, about 84 hours of work for those 1,000.
Above a few hundred, the unit price barely drops: every part still needs its machine time and its handling. That's the big difference from a mould.
How is a run split between several makers?
The key is that every part comes from the same reference, even if different people print it.
- 1
Post the project with quantity and date
The file, the total quantity, material, colour and when you need it. Offers arrive within 24–48 hours and say how many units each maker can take on and by when.
- 2
Approve a master sample
Before the run, one sample that fixes size, colour, finish and tolerances. Everything else is compared against it.
- 3
Same file and settings for everyone
Every maker prints the same file, in the same material and colour, with the same layer height and orientation.
- 4
Check each maker's first unit
Before each one starts their share, a photo with measurements or a physical unit to compare with the master sample.
- 5
Production in batches and shipping
Each maker prints and ships their batch. Ask for every box to be labelled so you know where each part came from if something goes wrong.
What needs to be fixed so every part comes out the same?
Material and colour with an exact reference
'Black PLA' isn't enough: two filament or resin manufacturers give different shades and finishes, and colour can vary slightly between batches. Give the manufacturer and the product reference, or ask every maker to use the same one.
Print settings
Layer height, number of walls, infill and orientation change the look, weight and strength. The safest approach is to take them from the maker who made the master sample and have everyone else copy them.
Critical dimensions and tolerances
If the part fits with another, mark which dimensions are critical and how much deviation you accept. In FDM a deviation of a few tenths of a millimetre is normal; what isn't specified can't be claimed.
Finishing and packaging
If supports need removing, or parts need sanding, painting or bagging one by one, say so from the start: with thousands of parts, every minute per part is hours of work and changes the price and lead time.
3D printing or injection moulding?
The point where a mould starts to pay off is usually between a few hundred and a few thousand identical parts, depending on size, shape and material. There's no single figure: it depends on the part.
3D printing when
- You need dozens to a few thousand parts.
- The design may change between one batch and the next.
- You need the first parts in days, not weeks.
- You want variants: different names, colours or sizes.
- You don't want to pay anything up front before you sell.
Injection moulding when
- You need many thousands of identical, simple parts.
- The design is final and won't change.
- You can pay for the mould up front and wait weeks for it to be made.
- You need the lowest possible unit price.
- The part needs a plastic or finish that printing can't give.
How long does a run of thousands of parts take?
Allow for three stages: the master sample (a few days), approval and the run. The machine hours in the table, divided by the number of printers working at once, give the minimum; add the handling (about 84 hours for 1,000 keyrings, according to the calculator), packing and shipping. Each offer states its lead time.
Medium runs are common: 4 of the 110 requests registered between May and October 2026 were for 21 to 100 units. The largest run requested from the network was 5,000 pieces.
During the launch phase you agree payment directly with the maker. If you need an invoice for your business, say so in the project so makers can take it into account in their offers.

FAQ about high volume 3D printing
Can you 3D print 1,000 parts?
Yes. A small FDM keyring takes about 11 minutes of machine time, so 1,000 is about 179 hours: over 7 days for a single printer, or about 18 hours per machine split across ten (Fabrishare calculator).
How much does it cost to 3D print 1,000 parts?
As a guide, 1,000 logo keyrings in FDM cost about €3,441, €3.44 each, and 1,000 28 mm resin miniatures about €3,897, excluding VAT and shipping (Fabrishare calculator). Each maker sets their own price in their offer.
Will the parts match if several makers print them?
Yes, if they all work from the same approved master sample, the same file, the same material and colour with its reference, and the same settings. Ask for each maker's first unit before they start their share.
At what quantity does injection moulding pay off?
Usually somewhere between a few hundred and a few thousand identical parts, depending on size, shape and material. The mould is paid up front and takes weeks; printing needs no mould and allows design changes between batches.
What's the largest run requested?
The largest requested from the network was 5,000 pieces. In the log, 4 of the 110 requests registered between May and October 2026 were for 21 to 100 units.
Resin or FDM for thousands of parts?
Resin for small detailed parts: many fit on one plate and time depends on height (1,000 miniatures, about 31 machine hours), but each one has to be removed and cleaned. FDM for functional and larger parts, with time growing with every part.
How long does a run of thousands of parts take?
A few days for the master sample, approval, then the run: the machine hours divided by the printers working at once, plus handling, packing and shipping. Offers arrive within 24–48 hours and each one states its lead time.
Can makers see my file?
While offers are being made, makers see the technical details and an image of the part, but not who you are or how to contact you, and they can't download the file. Only the maker whose offer you accept receives the file.
Can I get an invoice?
During the launch phase you agree payment directly with the maker. If you need an invoice for your business, say so in the project so makers can take it into account in their offers.
