Fused deposition modelling

FDM 3D Printing

The workhorse. Real engineering thermoplastics, printed layer by layer to ±0.5 % — fast enough for a Monday prototype and cheap enough for a batch of fifty.

A part being printed in engineering thermoplastic on a Fracktal FDM printer
What it is

Melted, Placed, Fused

FDM builds a part by laying a molten thermoplastic filament down one road at a time and fusing it to the road beside it and the layer beneath it. Nothing is cured, nothing is sintered — the part is the same polymer that went in on the spool.

That is the reason to choose it. An FDM part in polycarbonate behaves like polycarbonate; an FDM part in carbon-fibre nylon is stiff for the same reason a moulded one is. What you test is what you would eventually manufacture.

Why this process

Where FDM Wins

Four reasons it is still the first process we quote for most jobs.

Cheapest per cubic centimetre

No powder to recycle, no resin to cure, no tooling. For bulk plastic, nothing else comes close on price.

The widest material range

PLA to polycarbonate to carbon-fibre nylon. Twelve documented on this site, twenty-plus on the floor.

Genuinely large parts

Up to 700 × 400 × 400 mm in one piece — no bonding a big part out of small ones.

Fast turnaround

A small part goes on a machine the day the file lands. Nothing has to be batched to make the economics work.

Applications

What People Send Us

Jigs & fixtures

Line-side tooling in PETG and CF-Nylon, revised as fast as the process changes.

Functional prototypes

Full-size, in the polymer the production part will use.

End-of-arm tooling

Light, stiff carbon-fibre grippers built to the cell.

Housings and enclosures

ASA outdoors, PC where it gets hot, PP where it gets wet.

Short-run end-use parts

Tens to low hundreds, where tooling would never pay back.

Teaching and research models

Cheap enough to iterate, strong enough to handle.

How it works

Four Steps From File to Part

The same route for every process on this page.

01 · Upload your CAD

Pick a manufacturing process, upload the 3D file and tell us the quantity and finish.

02 · Get a DFM analysis

We come back with a design-for-manufacturability review and a price — not just a price.

03 · Manufacturing begins

Approve the quote and the job goes on the floor. You are told when it starts, not only when it ends.

04 · Parts are shipped

Packed, tracked and shipped anywhere in India, with the tracking number in your inbox.
