A biotech company sent us a file for a diagnostic device housing and asked for a price. The file was almost identical to one another company had sent the week before. The quote came out three times higher. Nothing was miscalculated. Same part, two different materials, two different technologies, two different accuracy requirements — that is the whole story of 3D printing pricing.
People expect a price list, the way a print shop has one: a gram of plastic costs this much, multiply by weight, done. Industrial 3D printing does not work that way. Below is exactly what makes up the price, where customers pay more than they need to, and how to get a quote that reflects what you actually need.
The short version
- There is no flat rate. Price comes from the combination of material, volume, complexity and accuracy — and moving any one of them moves the whole sum.
- Designing the file properly before printing — DFAM, design for additive manufacturing — can cut the cost of a part dramatically before the machine even starts.
- Regulated industries change the pricing, and rightly so. Medical, aerospace and defence bring standards and quality control requirements, and those are what make the part trustworthy in the field.
- A full service under one roof — printing through finishing — shortens the total project and avoids the problems that appear in the gaps between suppliers.
Why additive pricing works differently
Additive manufacturing builds a part layer by layer instead of cutting it out of a block. In conventional machining you start with a billet of aluminium and remove 80% of it as chips. In printing you place only the material you need, exactly where you need it.
That brings the first cost consideration: there is no tooling. Injection moulding needs a steel mould that costs tens of thousands before a single part exists. In printing you pay for the part itself, from the first unit.
This changes the whole economics of short series and prototypes. If you need fifty units of a complex bracket, a mould will never pay for itself. Printing gives you the fifty straight away, with no opening cost.
Geometry also stopped costing money. An internal cavity, an organic lattice, a winding cooling channel — all print as easily as a cube.
What actually drives the price
Every project is a unique combination of material, volume, complexity and accuracy requirement, and each of those moves independently. Two parts of the same size can be as far apart in price as an industrial printer is from a desktop one.
The real cost is a combination of machine time, material consumption and human hours in finishing. Here are the three heavy variables.
1. Material
The spread between materials is enormous. A standard polymer such as PLA or ABS for FDM sits at the cheap end and is perfectly good for a prototype that only has to prove form and fit. At the other end are engineering end-use materials — glass-filled nylon for SLS, rigid resins for PolyJet, and metal powders for aluminium and titanium alloys.
Titanium powder for an aerospace part can cost tens of times more than an ordinary plastic spool, before you account for the dedicated machine it needs.
The rule is simple: the material follows the requirement. Need a part that survives 200°C under load? You pay for the material that does that. Need a model for a meeting? Simple plastic will do.
2. Geometry and machine time
Machine time is usually the heaviest item. A tall part needs more layers, and more layers means more hours in which the printer is occupied and producing nothing else. But height is only part of the picture. Overhanging features need support structures, and someone has to remove those by hand afterwards.
That is the human cost people rarely account for. A bracket with five overhanging holes and a winding internal cavity can take half an hour of manual work per unit just to clean supports — and across a series that adds up fast.
Designing the file properly cuts that dramatically. Our engineers took 40% of the weight out of a part for an automotive customer and shortened the print at the same time, simply by replacing a solid block with an internal lattice that gives the same strength.
3. Accuracy and post-processing
Layer thickness is measured in microns, and every micron is paid for. A thinner layer gives a smoother finish and finer detail, but it also multiplies the number of layers and the machine time. Printing at 25 microns takes far longer than the same part at 100 microns, and that translates directly into price.
A part is also far from finished when it comes off the machine. Post-processing includes heat treatment to relieve stress in metal parts, chemical polishing to smooth surfaces, UV curing for resins, and painting.
We run finishing and painting in house — dip dyeing, metal coating and secondary machining — so all of it happens under one roof without sending the part out.
Which technology costs what
| Technology | Relative cost | Where it fits |
|---|---|---|
| FDM / FFF | $ | Prototypes, fixtures, large functional parts |
| MJF / SLS | $$ | Durable end-use parts, short series, complex geometry. Cost per unit falls as the build chamber fills. |
| SLA / DLP | $$$ | Fine detail, visual models, patterns |
| PolyJet | $$$$ | Full colour, multi-material, transparency |
| Metal | $$$$ | Aluminium, titanium, stainless steel |
Requirements that change the price
Medical, aerospace and defence work brings documentation, traceability and quality control that a general prototype does not need. That is a real cost, and it is the reason the part can be trusted where it matters. If your application carries a standard, say so in the first enquiry — it changes the material, the process and the paperwork, and finding out later is what makes projects expensive.

Print-only versus a full service
A bureau that only prints hands you a raw part and the remaining problems: supports, finishing, inserts, dimensional checks. Each of those becomes another supplier, another lead time, and another place where responsibility falls between the cracks.
We run seven printing technologies including metal, with finishing, painting, inserts and dimensional inspection in house, and more than 500,000 parts produced. In practice that means one conversation instead of four.
How to get an accurate quote
Send us these and the quote will reflect what you actually need:
- The CAD file — STEP, STP, IGES, 3MF or STL
- A drawing if any tolerance is critical
- Quantity — this is often the single biggest lever, because the powder processes get cheaper per unit as the chamber fills
- The date you need it
- What the part has to survive — load, temperature, chemicals, sunlight. This is what decides the material, and guessing here is what makes quotes wrong.
Minimum order is NIS 350 + VAT. Full commercial terms, including our published tolerances per technology, are in our terms.

We will come back with a recommendation on technology, material and price for the quantity you need — including if the answer is that a different process, or a change to the design, would cost you less.
