The flagship
SG-S 3D L2S PRO
Four colours in one print, the deepest returns in the range and the big bed, with UV curing and the filament dried on the machine, on a closed cabinet.
Square bed
1200 mm
1.44 square metres of bed: more of a set in one run, or one big letter. Also made with an 800 × 800 mm bed.
Returns
130 mm
Letter bodies up to 130 mm deep, for deep face-lit and halo letters. Bigger than the bed? Print it in sections and join them.
Colours
4 in one print
Four extruder heads feed one nozzle (4-in-1-out), so one letter can come off the bed in up to four colours.
Rated speed
40–300 mm/s
It can run overnight, unattended. If the power drops it carries on where it left off, and it stops if the filament breaks.
Made on these machines
Printed at night. Lit by morning.
Real letters from SG printers, on the bed as they were printed and finished with their LEDs. Printed face-down, so they read backwards on the bed.

How it works
From a CorelDRAW file to a lit letter.
If you can draw it, you can print it. No 3D modelling: the software turns your outline into a letter in one click.
Design
Your artwork in CorelDRAW, or a DXF from Illustrator. The same file you'd send to a fabricator.
Print
INC slices it in one click and shows a 3D view first. It can run overnight, unattended.
Finish
Fit the face and the LEDs: printed in the same run, or sheet acrylic or an infinity mirror fitted after the print.
Install
Mount it like any built-up letter. Bigger than the bed? It's printed in sections and joined.

FAQ
Questions sign makers ask
How much does a channel letter 3D printer cost?
Ask us for a price: it depends on the machine and the bed size (800 × 800 or 1200 × 1200 mm). Tell us what you print and we'll come back within 1 working day.
How does it compare with buying letters in?
A face-lit built-up letter bought from a UK trade fabricator costs about £57 at 300 mm, £97 at 500 mm and £117 at 600 mm + VAT, and takes 7–10 working days (typical UK trade prices for fabricated letters, five-letter job, checked 25 September 2026). Printed in your own workshop there is no minimum order, and the machine can print overnight, unattended. Bring a job you're quoting to a demo and we'll work through the cost with your numbers.
Do I need 3D design skills?
No. If you can draw it in CorelDRAW, you can print it: CDR or DXF in, one click in the INC software, no 3D modelling. On-site training is included*.
Can it run overnight?
Yes. It can run overnight, unattended. If the power drops it carries on where it left off, and it detects a broken filament and stops.
How big can a letter be?
The beds are 800 × 800 mm or 1200 × 1200 mm. The ULTRA and PRO ULTRA print returns up to 100 mm deep, the L1S and L2S models up to 130 mm. Bigger letters and logos are printed in sections and joined.
Will printed letters last outdoors?
HFPC, the letter filament for the range, is a modified polycarbonate and PETG blend rated from −40 °C to 65 °C and resistant to UV and oxidation.
What happens if it breaks?
Ring or WhatsApp our London team. Spare parts are stocked locally, so a fault doesn't wait on overseas shipping. 2-year warranty*. *Conditions apply, ask us for the terms.
Why not buy the same kind of machine direct from a factory abroad?
What you get from us is everything around the machine: it's assembled in the UK, on-site training is included*, spares are stocked in London, there's a team to ring, a showroom to see one run and a 2-year warranty*, and finance options are available for businesses. *Conditions apply, ask us for the terms.
Are printed illuminated letters legal on a building?
In the UK the letter body itself needs no certification. Use SELV (12 or 24 V) LED modules with a UKCA or CE-marked driver, have it wired to BS 7671 by a competent electrician, build and fix to BS 559-1:2023, and check advertisement consent: Class 4B deemed consent covers many lit shop signs, but not in conservation areas. This is a summary, not legal advice.
Can I see one before I buy?
Yes. Book a demo at our showroom at 17 Burnt Oak Broadway, Edgware HA8 5LD. Visits are by appointment.
Is finance available?
Finance options are available for businesses. Ask us.
