Valentine's Day is celebrated annually on February 14 in many countries of the world: for more than one and a half thousand years, millions of people on this day admit to each other in love.

Our 3D laboratory got its start due to the unsatisfactory print quality of companies operating in this market. One of our regular customers, the TOP-VR company, which sells VR attractions, contacted us. The creation of one of the attractions, Zaga-game, involved the development of additional accessories: a blaster into which the game joystick is installed; mounts for an additional power supply for a mobile virtual reality helmet and mounts a sensor on the head.

By "contactless marketing" mean the dissemination of information and the performance of any action (task) without human intervention. Everything happens by reading machine code without any human contact.

For example, a person was always needed to distribute leaflets. Now it is enough to place a QR code or NFC tag with a "call to action", a person can use a smart phone and immediately receive content. Content can be anything from advertising, entertainment, or social. It's very simple: "tap" on the smart phone screen and get what you need ("tap and save", "tap and load", "tap to link", etc.).

When we first started doing 3D printing, we assembled a simple printer with a 200x200 mm table on the basis of the H-bot system, ZAV cases and linear guides. We did not use cylindrical guides because the print speed on them is slower and the sag of a heavy print head is greater. Head slack can create problems when the nozzle hits the part and this can cause to the separation of thin supports from the table.
