Low-Volume Manufacturing for Product Brands: An FDM Buyer’s Guide
Fifty to a few thousand parts with no mould: the price per unit, the machine time, the hardware fitted and assembled — written up as a work order for your run.
For a product brand that needs anything from fifty to a few thousand of a plastic part, FDM printing is the fastest way from a file to finished units. There is no mould to pay for or wait on, the price per part is known before you order, and the design can change between one batch and the next. A phone stand that costs $6.16 as a one-off is $4.77 each at 250. Every one comes checked by a person before it ships. Write your own run up below.

What no tooling buys you
The hundredth unit can be a better design than the first.
In practiceLaunch in one colour, add a second next month, fix the clip that customers complained about in batch three. None of it costs a new mould.
What you get with a run
- A price you can plan on
- Every part is sliced on the profile it prints on, so the per-unit price is measured, not estimated. Copies that fit two to a plate take up to 30% off machine time, and material is always at cost per gram.
- Hardware
- Magnets, heat-set inserts, screws, rubber feet and MagSafe rings from a catalogue of about a thousand parts, at the part’s own price and packed with the run.
- Assembled, if you sell it with us
- A parts run ships as printed. A product you list with us can be assembled for a flat $1 a part, not billed by the minute.
- Checked, and remade
- A person inspects every part. Anything that fails is printed again on our time before the run ships.
- Any colour you need
- Sixty-five colours across ten materials on the rack, carbon-fibre PETG included. Anything else is bought in against your order.
- Two ways to deliver
- The whole run to your door in cartons, or nothing up front: each unit made as your customer orders it, shipped under your name from your store.
Where FDM fits, and where another process does
FDM is the right process for most plastic product parts in the tens to thousands: housings, mounts, clips, organisers, stands, knobs, accessories and replacement parts. Three other processes are worth knowing, because a good buyer uses each where it fits.
- Injection moulding
- Wins once a design is settled and volume reaches the thousands a year: the part price falls below printing, but only after tooling that starts around $1,500 and a lead time of its own. The break-even arithmetic for your own part is in 3D printing vs injection moulding.
- Resin (SLA)
- Wins on fine surface detail, such as miniatures and jewellery masters. The parts are more brittle and less suited to things handled daily.
- Powder nylon (SLS) and machining
- For parts that need nylon’s toughness without supports, or metal and very tight tolerances. Those are other services’ processes, not ours.
Before you order the run
01
Order one first
A single part through checkout costs a few dollars and ships within three business days. Hold it, fit it, drop it.
02
Pick the material by where it lives
A part left in a car needs a plastic that holds its shape past 69°C. Our guide to materials for everyday parts plots every one we stock.
03
Say what has to fit
Printed dimensions hold to ±0.5 mm or ±1%, whichever is greater. Design pockets for magnets and inserts to that band.
04
Decide how it ships
All at once to your warehouse, or made as it sells. The second needs no stock, no storage and no forecast.
Material choice, plotted for every plastic we stock, is in materials for parts people handle every day. Up to 500 parts are priced and paid at checkout, in seconds, from your file. Larger runs are quoted and scheduled: send the file and the quantity to support@printport3d.com. Our guide to an accurate quote lists the eight things to include.
FAQ
Producing tens to a few thousand units of a part, usually without the tooling that mass production needs. For plastic product parts, FDM 3D printing is the most common route: no mould, a known price per part, and a design you can change between batches.
It depends on the part’s weight and print time. As an example, a 72 g phone stand is $6.16 as a one-off and $4.77 each at 250, with the quantity discount applied. Upload your own file for its exact price at any quantity up to 500.
Yes. Checkout takes up to 500 parts in one order; larger runs are quoted and scheduled. Email the file and quantity to support@printport3d.com.
A parts run ships as printed, with any hardware packed alongside. Assembly is a choice you make on a product you sell through us: tick it and every unit is put together for $1 a part.
When the design is final and the volume is high enough that the tooling pays for itself — often somewhere in the hundreds to low thousands of units, depending on the part. Until then, printing avoids the tooling cost and keeps the design free to change.
