Printer with pencil lead instead of ink

The idea of ​​creating Pencil Printer belongs to the young Korean designer Ho Yong Lee. The innovative device has a number of advantages: simpler printing technology compared to inkjet technology; compact dimensions; environmental friendliness; much cheaper than inkjet and laser analogues.

Features of a pencil printer

The printer prints using a regular pencil, the lead of which is completely used during operation. The idea of ​​environmental friendliness was at the forefront of the young designer’s mind.

Reference! The new printer uses recyclable materials - leftover leads that were previously simply disposed of.

Before the creation of the Korean device, only plotters, devices for printing graphic products (maps, diagrams, drawings), could print with a pencil. The devices are often called large-format printers due to the similarity of their functions. The lead in plotters moves with the help of an electric motor, so the operation of the equipment is accompanied by increased noise. Pencil pen models are characterized by high print quality at low speed. Even electric motors optimized for this model cannot increase it.

The mechanism of operation of the device

The new pencil printer only works with wood-framed products. All you need for printing is a graphite rod. The remainder of the pencil is placed in a special sharpener on the surface of the device.In the sharpener, the pencil is cleaned from wood, and the lead itself is ground into powder. Printing is done not with a pencil, but with slate powder, which becomes a substitute for ink. An innovative development is also the built-in eraser cartridge.

Reference! Experts call the new model both ingenious and senseless, doubting that it will be put into mass production. Most likely, it will become an exhibit in museum or private collections

What can a pencil printer do?

In addition to the usual function of printing texts, which is basic for all types of printers, the pencil model has an innovative one - erasing unnecessary information.

An error made in the text can be easily erased with a regular eraser, which cannot be done with text printed in ink.

A sheet of printed text that has lost its relevance can be reused. To do this, you need to pass it through a special eraser cartridge, which will erase all text information.
