Custom 3D printing · Prototypes
Functional prototypes without owning a printer
Testing a product idea, a bracket, an enclosure, a jig? Upload the STL, pick an engineering-grade material if you need it, and have the part in hand in days — printed by a vetted maker, covered by the 5-day guarantee.

Iterating on a design means printing the same part again and again with small changes. Ez3dprint is built for that loop: upload the next revision, get an instant quote, and the job goes to the closest qualified maker. Multi-part orders are priced together, so printing three variants of a bracket at once unlocks the bulk discount.
For functional testing, material choice decides whether the prototype tells you anything useful. PETG is the workhorse for fit and function checks. Nylon and carbon-fiber blends (PA-CF, PETG-CF) handle mechanical load, heat and wear — many Ez3dprint makers stock them. If the part just needs to look right for a demo, PLA at a fine layer height is the cheapest good-looking option.
What to put in the order notes
Flag tolerance-critical features — 'this bore must fit a 10 mm dowel' lets the maker calibrate or adjust. Note which faces are cosmetic so they orient the layer lines away from them.
Choosing a material
PETG for general functional tests. Nylon or PA-CF for parts under real mechanical load. PLA for form-and-fit mockups. TPU for seals, bumpers and anything that must flex.
Order variants together
Uploading several revisions in one order means one flat $9.99 shipping charge and a spend-based bulk discount across all of them — cheaper than ordering one at a time.
What prototypes actually cost
Indicative prices from Ez3dprint's live pricing engine for typical prototypes specs. Your exact quote is computed from your file's real geometry on the custom job screen.
Enclosure (PETG)
≈79.9 g · ≈5.2 h print time
$26.96
+ $9.99 flat shipping per order
Load-bearing bracket (PA-CF)
≈51.4 g · ≈5.9 h print time
$28.18
+ $9.99 flat shipping per order
Fit-check mockup (PLA)
≈41.9 g · ≈1.7 h print time
$13.18
+ $9.99 flat shipping per order
Orders over $50 of printing get an automatic bulk discount of 3–10%.
How ordering works
- Upload your STL — the mesh is read in your browser for real volume and dimensions.
- Pick material, color, infill, layer height and supports; the quote updates live.
- Ez3dprint matches the job to the closest maker whose printer fits it and who stocks your filament.
- Pay by card. The maker prints, we send them a prepaid shipping label, and tracking updates automatically until delivery.
