How Much Does 3D Printing Cost? Full Breakdown

Quick answer: a small PLA part of up to 50 g costs roughly $1 to $3 to produce, counting filament, electricity and machine wear. A 30 ml resin miniature runs about $2 to $5. The rule underneath those numbers is simple: the real cost of a print is two to three times the value of the material it consumes.

Count only the filament or the resin and you will be well under — which is how most people end up selling below cost without noticing. This article covers both sides of the question: what a print costs you if you own the printer, and what it should cost if you are paying someone else to print it.

3D printing cost per gram

The material share is quick to work out. Take the spool price and divide by 1,000 — that is your material cost per gram. PLA filament averages $15 to $25 per kilo, so material alone lands at $0.015 to $0.025 per gram. A 40 g part consumes 40 times that.

But that figure describes the material, not the production. Once you add electricity, machine depreciation and the prints that fail, the real production cost sits closer to $0.04 to $0.07 per gram. That is the two-to-three multiplier in practice, and it is more useful than any absolute figure because the ratio holds whatever currency you buy in.

The full calculation, line by line

Material actually used. Not the whole spool — the grams that end up in the part, plus what goes into supports, skirt and purge. Your slicer reports this before you print, and it is the only line most people count.

Electricity. Printer wattage times print hours times your price per kWh. On FDM this is smaller than most people expect: the heated bed draws more than the hotend, and both cycle rather than run continuously.

Machine depreciation. Purchase price divided by expected service hours gives you a cost per hour that belongs in every job. Skipping this line is the single most common reason hobbyists undercharge — the machine wears out invisibly until it needs parts nobody budgeted for.

Consumables. Nozzles wear, build surfaces lose adhesion, belts stretch. On resin, add isopropyl alcohol, FEP film and the LCD's exposure life. Each has a cost per print once you divide by how long it lasts.

A failure allowance. Nobody prints at a 100% success rate. Budgeting 5 to 10% on top of production cost covers the failed prints without eating your margin.

Your time. Setup, monitoring, support removal, sanding. On resin, washing and curing are mandatory rather than optional. This is the line hobbyists leave out and professionals never do.

What a part actually costs: worked examples

• Keychain, 10 g, about 40 minutes: $0.40–0.80 to produce, sells for $3–5.
• Phone stand, 40 g, about 3 hours: $1.60–2.50 to produce, sells for $5–10.
• Resin RPG miniature, 15 ml, about 4 hours: $1–2 to produce, sells for $8–15.
• Large cosplay piece, 800 g, about 40 hours: $30–50 to produce, sells for $100–200.

Notice what the spread between cost and price tracks: not weight, but how hard the part is to get right. The miniature costs less to produce than the phone stand and sells for more, because resin detail is what the buyer cannot reproduce themselves.

What actually drives the price

• Weight, not size. A hollow enclosure can weigh less than a small solid block.
• Print time, which sets electricity and depreciation — and it grows with height, not footprint.
• Infill and wall count. Going from 15% to 40% infill nearly doubles material without making the part twice as strong.
• Supports, which are paid for and thrown away.
• Failure rate, which is the difference between a hobby and a business.

FDM or resin: which is cheaper?

Per part, FDM wins. Filament goes a long way and brings no extra consumables. A spool sits on a shelf between jobs and costs nothing while it waits.

Resin costs more per litre and drags a chain of consumables behind it: alcohol that gets dirty and must be replaced, FEP film good for 20 to 60 prints, an LCD screen rated in exposure hours, plus gloves and paper towel on every single part.

What resin buys you is detail FDM cannot reach — and that is where the margin lives. Miniatures, jewellery and fine-fit prototypes sell at multiples of their cost precisely because FDM cannot produce them. Filament wins on volume; resin wins on value.

What 3D printing services charge

If you do not own a printer, you are asking a different question — and the answer has a different shape.

Print services generally price on some combination of material volume, machine time and post-processing, with a minimum order that covers setup. That minimum is why a tiny part often costs almost as much as a medium one: the labour of preparing the job does not shrink with the part.

Expect meaningful differences by process. FDM is the cheapest quote you will get. Resin costs more for the same volume, because of the consumables and the mandatory washing and curing. SLS costs more again but needs no supports, so complex geometry does not add to the bill the way it does elsewhere. Metal sits in another category entirely — machine, inert atmosphere and mandatory heat treatment dominate the price, which is why printed metal competes on geometry rather than cost.

When comparing quotes, check what is included. Some prices assume you accept the part as it comes off the plate, supports and all, and finishing is what turns a cheap quote into an expensive one.

Does buying a printer pay off?

The honest test is volume. A machine only pays for itself once the per-part saving times the parts you actually print exceeds the purchase price plus the months you spend learning it. Print twice a year and a service is cheaper; print every week and the machine wins quickly.

Where the tiers sit today:

• Entry FDM (Creality Ender-3 V3 KE): the learning tier. Cheapest way in, and you will spend time on calibration.
• Plug-and-play FDM (Bambu Lab A1 + AMS Lite (Combo)): fast, quiet, and it works out of the box. The combo adds multi-colour; the bare machine costs noticeably less.
• Entry resin (Elegoo Mars 5 Ultra 9K): 9K detail, sized for miniatures.
• Large resin (Elegoo Saturn 4 Ultra 16K): more build volume at 16K resolution, for batches or bigger pieces.

What to charge if you sell prints

The common rule in the maker market is total cost multiplied by 1.5 to 2.0 — a 50 to 100% markup. Add your modelling and finishing time, and shipping.

The critical detail is that the multiplier applies to total cost, not to the material price. Apply it to filament alone and you are selling below cost, and you will only find out months later when the machine needs parts you did not budget for.

Custom work, rush jobs and anything requiring design time justify a higher multiplier. Repeat production of a proven part justifies a lower one, because the failure rate is known and the setup is already done.

How to spend less without changing material

• Drop infill before anything else. It is the single biggest material saving that does not change how the part looks.
• Rotate the model to remove supports. Most printers handle overhangs up to about 45 degrees unaided.
• Add wall loops instead of infill when you need strength. Cheaper in both material and time.
• Hollow resin models before slicing, with drain holes. The easiest saving available on that side.
• Fill the plate on resin. Print time depends on height, not part count — one miniature or eight at the same height take the same time.
