Let the printermove on the paper.

A printer that travels across whatever it prints on, so the print can be any size. Anytime, anywhere.

Project: 2.5D Printer

Dimensions: Millimetres

Printers and paper have always limited each other

Every printer today

1Paper has to be fed into the printer.
2So the printer must be wider than the paper.
3Office printers stay bulky. Small ones only print slips and cards.

The 2.5D Printer

1The printer moves on the paper instead.
2Its own size no longer limits the size of the print.
3Set it down on a desk, a book, a board, a wall or a floor.

Have you been in one of these moments?

Why walk ten minutes and queue for five just to print one page?

Documents, posters, notes: print whenever and wherever you want, even straight into a bound notebook. It is small enough for a crowded dorm desk.

Everything a desktop printer does, run from your phone

It connects to your phone over Bluetooth, and everything runs from the app.

Print documents: Word, TXT and PDF files, down to the pages you pick.
Print photos: Straight from the camera roll, the moment you take them.
Scan and copy: The phone camera captures the page and the printer copies it.
AI assistant: Voice control, conversation and meeting transcripts.

Long documents too

Foldable stands let it move on to the next page by itself, the way an office printer would.

Beyond printing

A 3D printing module and special inks turn printing into making.

Module

3D printing

With a 3D printing module on the base, it builds objects layer by layer. The machine moves as it builds, so an object can be larger than the machine itself.

Conductive ink

Circuit boards (PCB)

Print a working circuit board on your desk in one step, and test the design while the idea is still fresh.

Cost	about £42	under £1
Time	up to two weeks	minutes

Also

Flexible circuits on skin: Sensors and tags printed straight onto the skin, with no adhesive backing.

UV ink

UV printing

UV ink, set by a curing light, lets it print on glass, plastic and foam, surfaces ordinary ink will not stay on.

Used for

Microfluidic channels: For research labs: channels printed on plastic or glass, where paper-based chips leak or tear.

Smaller than a coffee mug

Size: Under 0.3 litres, about the size of an apple
Weight: About 300 g
Battery: 8 hours of printing
Running cost: About 1p a page on plain paper
Prints on: Paper, books, wood, fabric, walls and floors
