How Are 3D Printing Prices Calculated? Grams, Time, Material

A 3D printing price is the sum of four items: the material that goes into the part (in grams), the time the machine spends printing, finishing work such as support removal and painting, and modelling if you don't have a file. Two parts of the same size can be priced very differently because of infill and material. An accurate quote needs dimensions, quantity and where the part will be used.

We don't give a per-gram or per-hour TL figure in this guide. Filament and electricity prices change often, and a single number would mislead you. Instead we explain how each item pushes the price up, and what to prepare before you ask for a quote so the process goes faster.

What makes up a 3D printing price?

You see one total on the quote. The calculation behind it looks like this:

• Material: Filament is sold by the kilogram, usually on 1 kg spools. The slicing software calculates how many grams the part will weigh before printing. Support structures are included in that weight; they're removed and thrown away after printing, but they're paid for.
• Machine time: In most jobs this is the biggest item. The printer is busy with one part for hours and can't print anything else in that time. Electricity and wear on consumables such as the nozzle and build surface are included here too.
• Preparation: Checking the file, placing the part on the bed, choosing which way up to print it. A few minutes for a clean file, up to an hour for a faulty one.
• Finishing: Support removal, sanding, filling, priming, painting. It's manual work, so it's measured in hours.
• Modelling: A separate item if there's no file. We cover it below.

There's also a hidden item: the risk of a failed print. If a part lifts off the bed in hour 15 of a 20-hour print, both the material and the time are lost. For large, thin-walled parts, whoever quotes will factor that risk in. It's better to see it as a kind of insurance than as extra profit.

A concrete comparison helps. Picture two phone stands of the same size. The first is printed in PLA at 0.2 mm layers, 15 percent infill, raw surface. The second is PETG at 0.12 mm layers, 40 percent infill, then sanded and painted. The second weighs more, has about 1.7 times as many layers, and adds a few hours of handwork on top. To an onlooker both are phone stands. Their invoices are not the same.

How does the type of material change the price?

The price per kilogram of a material affects the total less than people expect. The real difference comes from how easy the material is to print.

PLA is the most common and easiest filament to print. It prints quickly and fails rarely, so it's usually the most economical option. For decor, models, prototypes and parts that stay indoors, it's often enough.

A spool of PETG costs about the same as PLA. Printing it more slowly and cleaning up the fine strings it leaves (stringing) can add a little time. In return you get a part that handles moisture and impact better than PLA.

ABS and ASA handle heat better, but they need an enclosed printer and good ventilation. They tend to shrink as they cool and lift at the corners. On large parts the risk of failure rises, and that shows in the price.

TPU is a flexible material and has to be printed slowly. Same geometry, longer print, higher price.

Colours and speciality filaments are a separate matter. Silk-finish, marble-effect or wood-filled filaments usually cost more than standard colours. Carbon fibre or glass fibre filled filaments go a step further: they're abrasive, so they need a hardened steel nozzle and wear out an ordinary brass nozzle quickly. With these materials, machine wear also goes into the price. Asking for "black PLA" is not the same as asking for "matte black, carbon filled". If you want the second, say so from the start.

How do layer height and infill affect print time?

Filament (FDM) printers build a part from thin layers stacked on top of each other. With the common 0.4 mm nozzle, layer height is usually set between 0.1 and 0.3 mm. The maths is simple: a part 10 cm tall takes 500 layers at 0.2 mm and 1,000 layers at 0.1 mm. Double the layers and the print time roughly doubles too.

What you get for thinner layers is a smoother surface. For a model that will be handled or photographed, that's worth it. For an assembly part that sits inside a box, it usually isn't.

Infill is how solid the inside of the part is printed. For a decorative part, 10 to 20 percent infill is enough. A bracket that carries load needs higher infill and thicker outer walls. The first step to a stronger part is usually not more infill but more walls. It adds less weight and more strength.

The orientation of the part also changes the time. A long rod printed lying down finishes with few layers and no supports. Printed standing up, the layer count multiplies. Orientation also depends on where the part takes load, because the bond between layers is weaker than the layer itself. A part printed so that the force tries to pull its layers apart will crack at its weakest point.

What if you don't have a design file?

A 3D printer only prints a digital model. Without a file, that model has to be drawn first, and that work is priced separately from printing. A flat cover or a spacer is quick. A figure with organic shapes, or a multi-part mechanism whose pieces have to fit together, can take days.

It depends on what you have.

If you have a dimensioned drawing or a technical drawing, modelling goes quickly; the dimensions are already known.

If you need a replacement for a broken part, the part is measured with callipers and redrawn. Bringing the broken part itself gives a far better result than a photo. For parts that have to fit, the dimensions are often confirmed with a small test print; a test of a few grams is cheaper than a large part printed at the wrong size.

If all you have is an idea, you first need to agree on a sketch and dimensions. Skipping that step is the most expensive mistake.

The file format matters too. STL is an output format that describes the surface with triangles; it's fine for printing and awkward to edit. STEP is an editable CAD format that keeps its dimensions. If the part may change later, asking the designer for a STEP file as well saves time down the line.

If you want your logo printed as a keyring, a desk sign or a raised plaque, you'll need a vector file of the logo (SVG, AI or PDF). If all you have is a low-resolution PNG, a clean vector version has to be prepared first. For work on logo files, see our graphic design service.

One part or a small batch?

Printing a single part has a fixed cost: checking the file, choosing the material, the first setup, perhaps a test print. That cost is shared as the quantity grows, which is why the unit price drops noticeably between 1 and 10 pieces.

After a certain point, the drop slows down. Each part still needs its own machine time; 10 parts means roughly 10 times the print time of one. Several parts can go on the bed at once, but total time still depends mostly on total volume.

3D printing makes sense for a small batch when:

• The quantity is in the tens or low hundreds
• The design may still change (changes are expensive once a mould is made)
• Each part is personalised with a name, size or colour difference
• You want to see demand before investing in a mould

Once the quantity reaches the thousands, moulded production such as plastic injection usually wins on unit cost. In that case 3D printing is useful at the prototype stage, before the mould.

Prototypes work a little differently. The first print is almost never the last. A hole comes out 0.3 mm too tight, a clip snaps, a corner digs into your hand. Budgeting two or three rounds of test prints from the start is more realistic than asking for a new quote every round. When you get a quote, ask how reprints are priced as well.

What should you prepare before asking for a quote?

The more information you give in your request, the closer the first price will be to the final one:

• File: STL, OBJ or, if possible, STEP. Without a file, a dimensioned drawing, a sketch or the part itself.
• Dimensions: Width, depth, height. If it fits into another part, the exact dimensions of that area and the acceptable tolerance.
• Quantity: How many you need today and how many you might need later.
• Where it will be used: Indoors or outdoors? Sun, heat, moisture or load? Will it stay inside a car?
• Surface: Is a raw print enough, or do you want sanding and paint? Which colour?
• Date: When do you need it?

If you're sending a photo of a broken part, put a ruler next to it. Without scale, dimensions from a photo are only a guess, and a guess often costs a second print.
