3D Printing Technology Leaps, Are Plastic Toys Harmful?

3D printing technology has advanced, are "plastic toys" still harmful? From pilot products to mass production, 3D technology has now been successfully brought to market. There are 3D printers aimed at high-end designers, as well as 3D printing pens aimed at younger people.

However, with the development of the market, 3D technology has also been controversial, especially the current stage of 3D printing raw materials still cannot be separated from the category of "", although the news often reports the use of new materials such as corn flour, silica gel or resin. However, plastics are still the mainstream of the market due to their low price and good plasticity.

Therefore, some people say that 3D printing is still "", and from this perspective, there is some truth. This 3D pen is more controversial than 3D printers, because 3D pens are more suitable for children's toys in terms of positioning, and many plastic toy manufacturers are developing for the children's market.

Compared with the fine modeling of 3D printing, the 3D pen is more casual, creative and artistic in drawing, and many parents also buy it as a toy or teaching aid to motivate their children.

However, the current popular 3D fountain pens on the market are based on the principle of hot melting, that is, the plastic is digested and heated through the pen tip to achieve a plasticizing effect. After the plasticizing temperature drops, it solidifies into a 3D work. The temperature of melting plastic 3D pens tends to be high and there is a risk of burns. Excessive melting temperature can also produce a pungent odor, which is harmful to young children's bodies and the environment.

For these problems, manufacturers have also adopted many methods to solve these problems. Some manufacturers have developed PLA as a raw material in addition to ABS as a raw material, and some manufacturers have developed a 3D pen as a raw material, but from the feedback, the performance of this material is still To be tested.

Recently, on Taobao crowdfunding, a 3D pen named "Starting Line" was registered. This pen has made breakthroughs in the development of "Light Curing Technology". The consumables are made of photosensitive materials. The consumables are stored in the refill in a liquid state. The 465 nm visible light with a special color is installed on the tip of the pen, and the consumables are quickly cured after irradiation. The maximum temperature of the three-dimensional brushstroke is 20°C, and the photosensitive material used is non-toxic and harmless, which greatly reduces the danger of brushstrokes and improves the safety of brushstrokes.

In recent years, 3D pens and 3D printing technology have seen a blowout trend. In addition to the new technologies mentioned above, more and more iterations and new materials have appeared in 3D printing, and the price has become more and more affordable. Before the advent of "cloud 3D printing", there were already thousands of machines using high-precision 3D printers to print models, and this was only shared by dozens of machines.

I firmly believe that in the near future, more and more mature 3D products will appear, and 3D technology will quietly enter each of our families.
