The era of 3D printing has arrived! Today, "", which has been regarded as a foreign technology, has finally entered the vision of the general public in China. In our daily life, we will find its shadow, especially in the medical field, such as 3D printing of human organs, 3D printing of skin and so on. We can also see 3D printing in every corner of life, fashion, jewelry, lamps, food, and so on.
Question 1: I want to buy a 3D printer. How much is it?
The price of 3D printers ranges from 2000 to millions, and there are also DIY works. From 2000 to millions? Why are the prices of so different? The reason is that 3D printers are divided according to technical principles, including SLA molding technology (light-curing), FDM molding technology (melt deposition), and other molding technologies.
Different molding technology, the cost is not the same. FDM technology 3D printer is the most common and the lowest cost 3D printer. The price of 3D printers with FDM technology ranges from thousands to tens of thousands of yuan. Generally, the larger the size of 3D printers, the higher the cost, even tens of thousands of yuan, because the larger the size of 3D printers, the higher the requirements for the manufacturing process and the stability of the machines. For example, the z-axis size of Hongrui Z500 has reached 560mm, which is much higher than that of ordinary desktop 3D printers 300m M below the molding volume, so the price should be more expensive, more than 40000.
Question 2: can we only use plastic materials?
Plastic is the most commonly used and the lowest cost material, which can meet the needs of daily printing. But now, paper, ceramics, metals, food, biological materials and so on can be used for printing.
Question 3: is the 3D printer market so hot?
According to the latest market research report, the 3D printing market is expected to reach US $30.190 billion by the end of 2022, with an annual growth rate of 28.5% from 2016 to 2022. The report predicts that due to the government's policy and financial support and extensive industrial infrastructure, the growth of 3D printing market in the Asia Pacific region (APAC), where China and Japan are located, will surpass that of the United States at a faster speed from 2016 to 2022.
Question 4: does the use of 3D printers have legal and moral problems?
Guns are strictly controlled all over the world. Even in the United States, the government is still very strict in the control of guns. If one day anyone in any corner of the world can print guns at will with their own 3D printer at home, the world will inevitably fall into a panic and disorder. Although people who maliciously use 3D printing technology should be punished, whether even 3D printers should be included in the legal restrictions remains controversial. At present, most countries support the development of 3D printing technology, and the government and other relevant public institutions are actively promoting 3D printers.
Question 5: is 3D printer a new technology developed in recent years?
In fact, 3D printers have been around for nearly 30 years. The earliest 3D printer was invented by American hurl in 1986. However, many people in China say that it seems that the concept of "3D printing" has only been heard frequently in recent years. Why? Since 2012, with the large-scale publicity of the media, 3D printing technology has been gradually heating up in China. Many enterprises have successively invested in the 3D printing industry. The competition in the domestic 3D printer market has become increasingly fierce, and 3D printers are more and more developing in the civil field It's a trend.
