1 ComeTrue 3D printer operating principle
ComeTrue 3D printer combines inkjet technology and rapid prototyping technology, it can produce a
three-dimensional product rapidly, and its operation is similar to produce a real product which uses printing
technology. The materials used are composite powders and binder, utilizing combination of binder and
powder to produce a real product. The method used is lamination method, which paves one layer of powder,
and then spray binder in the specific place. .Paving powder and spraying binder repeatedly until the product is
finished.

every two weeks.
2. If you do not print for more than two weeks, remove all the binder from the cartridge and the pipe then
thoroughly clean the pipe with water and then reinstall the binder until next time when you use.
3. The extracted binder can be stored in a clean and sealable container or empty used cartridge (the cartridge
must be sealed) until next time when you use.
4. After cleaning the binder pipe, please put the print head back into the Carriage and
ensure that the print head has returned to the Cap to prevent it from
drying out.
