What is 4D printing? What are the concept stocks?

Related: market hype! 4D printing concept stock list (list) Skylar Tibbits believes that 4D printing allows for a fundamental shift in rapid modeling. With 3D printing pre-modeling and then use the material to form is not the same, 4D printing directly to the design built into the material, simplifying the process from the "design concept" to "physical" to create things. It allows objects to be created "automatically" like machines, without the need to connect any complex electromechanical equipment. Currently, the composite material for 4D printing is supplied by the technology company Connex, with the ability to change shape embedded in the material. In order to take full advantage of this new technology, Autodesk's R&D team has also designed new software, Cyborg, which can be used to self-assemble and programmable analog materials, optimize designs and fold materials. Traditionally, the process of building things is generally, first simulation and then manufacturing, or building things while adjusting the simulation effect. Through the close integration of hardware and software, Skylar Tibbits hopes to disrupt the traditional way of building things through 4D printing. Affected by the above news, yesterday Boyun new material (002297 shares bar, market, information, the main buy and sell) (39,484,000 yuan), Farsheng (000890 shares bar, market, information, the main buy and sell) (288,574,000 yuan), western materials (002149 shares bar, market, information, the main buy and sell) (17,751,200 yuan), have research silicon stock ( 600206 shares bar, quotes, information, the main buy and sell) (16.9828 million yuan), Lepu medical (300003 shares bar, quotes, information, the main buy and sell) (13.8801 million yuan), Bowei alloy (601137 shares bar, quotes, information, the main buy and sell) (13.0542 million yuan), Purple shares (000938 shares bar, quotes, information, the main buy and sell) (11.5331 million yuan), the company has a total of 1,000 million yuan. ) (11,533,100 yuan), Sheng Laida (002473 shares, quotations, information, the main buy and sell) (10,177,500 yuan) and other conceptual stocks of 4D printing were more than 10 million yuan of large single funds sought after. Farsheng, Sheng Laida, western materials, Bowei alloy, Bo Yun new material, Yunhai metal (002182 stock bar, quotes, information, the main buying and selling), Lepu medical, research silicon stocks and other 4D printing concept yesterday rose more than 5%. Obviously, the current A-share listed companies with 4D concepts associated with the company are not industrialized to promote, but the 4D hot wind across the ocean has been the A-share market blowing red. Previously, the U.S. government attaches great importance to the demonstration effect produced by the 3D printing concept of 3D printing, the subversive traditional way of making things 4D printing concept has also been favored by many institutions. Soochow Securities (601555 shares, quotes, information, the main trading) said, 4D printing technology, is a material that can automatically deform. This automatic deformation of the material into the water, it can be designed in accordance with the product automatically folded into the corresponding shape. 4D printing is not only able to create a smart, adaptable new things, but also can completely change the traditional industrial printing and even the construction industry. Therefore, the 4D concept stock has a very broad prospect, it is worth investors to focus on. Jinbailin consulting believes that 4D printing was speculated, mainly because the technology is in line with the new industrial direction, imagination space is larger, the market as long as there is hot money continues to pour in, can repeatedly active. With the U.S. Pell Technology joint venture production and sales of "nickel titanium" memory alloys Falsheng; hold research billion gold new materials company 4.35% stake in research silicon stocks; engaged in powder metallurgy runic composite materials research Bo Yun new materials, metal fiber production of western materials may be involved in the concept of 4D printing. It should be reminded that there are analysts pointed out that, as if the previous two years of hot speculation of the concept of the Internet of Things, then envisioned a beautiful scene is that the television, refrigerator, rice cooker are automatically networked through the Internet of Things platform, you can make the family electrical appliances automatically begin to move. Moreover, if you go to the supermarket, you don't have to wait for the checkout, just push it out directly, and the total price of the basket of items can already be charged to your credit card. It all looks very nice and attractive, but unfortunately, when it comes to the stock market, it becomes a wave of speculation. Investors need to be sensible, 4D printing concept is just a kind of market speculation, sooner or later to appear back to the prototype.
