Additive manufacturing breakthrough innovative 3D printing pen can also transform 3D printer

Those who have played 3D printing pens should notice three things: first, the 3D printing pen is very fun; second, the price is cheap; third, the human arm is too low precision compared to digital instructions. So the question is, if the 3D pen is controlled by the computer? Recently Tinkernut gave an answer - transforming the 3D pen into a complete printer.

With the continuous breakthroughs and innovations in additive manufacturing technology, more and more people are beginning to have a strong interest in the extreme application of 3D printing. Gradually, various industry sectors have turned to 3D printing to see how this technology can bring new developments to the industry. However, the price of 3D printers has made many people's enthusiasm into daydreams, because the most popular entry-level 3D printers cost at least $300. For many people who want to become a guest, the price is still very high.

Of course, with the popularity of 3D printing technology , the price of low-end 3D printers will eventually fall and become a popular consumer goods, but before the day comes, beginners need to find a clever alternative. Daniel shared a method on Tinkernut to make a basic printer with a 3D printing pen. The resolution of this printer is not very high, but it is very interesting and the price is very low, only $100.

Although Daniel's machine looks rough, the necessary parts for the print bed, hot end, and extruder are complete. The most difficult part is the print bed, but Daniel solved the problem with three optical drives, which is very convenient. Assembling the extruder and the hot end can be difficult, but fortunately, there is now a very easy way to get a cheap hot end, which is the 3D printing pen mentioned at the beginning of this article. It is good to use a 3D printing pen. Part of the functionality of a 3D printer is achieved without the need to assemble a bunch of expensive components.

Daniel uses the Arduino to control the 3D pen switch, which is the most important part of the printer. Daniel outlines the entire circuitry that controls the print pen so that it can be operated from a microcontroller.

Of course, the print quality of this printer is not so good, but Daniel proves that a basic consumer-grade 3D printer can be built within $100.
