While time is the most precious resource to assure life, medical equipment is the most effective strategy to ensure safety during epidemics. The country's most pressing problem is how to deliver the greatest number of medical gadgets in the shortest amount of time. Modern medical device manufacturing techniques are being used by people from many walks of life. In the last several months, 3D printing has risen to the top of the list. 3D printing is being used urgently by a number of significant companies to make protective masks. They hope to use this as a stepping stone to the fabrication of other automotive parts in the future. Due to the standard injection molding technique, many people feel a sense of panic. What will become of the traditional injection molding industry's workers if 3D printing becomes popular? As far as I know, 3D printing is not capable of producing all automobile parts. Whether or not 3D printing technology can be instantly applied to the car sector to replace old procedures is the subject of this guide.

Is it possible to immediately use 3D printing technology to the automotive industry?
Three-dimensional printing has been around since the mid-1990s. The world's first 3D printer was developed in 1986 by humans. Patents for 3D printing technology were initially awarded to MIT. The study of 3D printing expertise indicates that this technology does not necessitate expensive mechanical equipment or molds. Because 3D data can be instantly translated into physical things, mold development and verification can be streamlined. With the wide range of items it is capable of processing, it can handle virtually every industrial good. In theory, it should have taken over the world's food processing industry and replaced all of the current methods of production. As a matter of fact, 3D printing technology has been used to create a few aircraft and cars during the past two decades. Neither Boeing nor Airbus have used this technology to mass create aircraft, nor have we seen Tesla, a proponent of cutting-edge technology, use it to print batteries and rockets. Is there any obstacle that has not been overcome?
There are only so many ways we can come up with a plastic bumper if the OEM insists we do so.
Naturally, the most widely used approach is machining. At this point in the design process you should acquire a large piece of plastic raw materials that is greater than the bumper volume and then use programming to remove unneeded areas using equipment milling, drilling and other methods to build quick prototyping parts in the design stage. Additionally, the method's drawbacks are evident. A lot of materials are thrown away, and certain structures can't be built in one sitting. With a 3mm diameter boss column, for example, the bumper can be directly produced with a height of 6mm. Additionally, it must be treated on a separate machine and then attached with adhesive, which does not ensure strength. The entire process can be completed in a week, but only one can be done at a time. The capacity and efficiency have been established.
After designing and making the relevant mold using the 3D data, you can then use injection molding equipment to melt the plastic and inject it into your mold. Trimming is possible after cooling and shaping. A professional team needs at least three months to create and approve a bumper-sized mold, and the mold development costs can be in the millions. This is a mass-production-ready approach. At least a hundred pieces per day can be produced after mass manufacturing has been validated to be qualified in the early stages.
Is it simple to make things using a 3D printer?
In this case, the substance is what makes all the difference. Printing a bumper using conventional PP material is not possible due to the inability to directly bind the layers, as described above in the body of the document. Since the ink used by office printers has the above properties, all 3D-printable materials must as well.
Because it is a 3D printer, it can be quickly and easily transported to its specified location.
In the defined area, it must retain its original form.
There must be a direct connection between each layer.
A strong bond can't be formed between the bumper's original PP particles. There's no way of making him stay in his original form no matter how much heat they put on him (injection molding, anyone?). Storage and transportation in liquid form is required, and it must be quickly solidified. Although practicality is taken into account, the cost and environmental circumstances cannot be allowed to become unacceptably high.
As a result, researchers have developed photosensitive resin. Set up a lifting platform in the center of a storage appliance filled with photosensitive resin before printing. Under water, the platform maintains its distance from the point where air meets liquid. In microns, this distance represents the thickness of each layer of the product you are printing. Beams of UV light are emitted from above the liquid level. Because of the platform's obstruction, light can only flow through the liquid if there is some space between the platform and the level of the liquid. It's like printing a layer of material when the irradiation photosensitive resin reacts and solidifies. The plane contour of this layer can then be printed by changing the area of ultraviolet irradiation based on the shape of the product being printed. Finally, print out each layer's materials and build up the three-dimensional outline by moving the platform continuously. It's the first top-down stereolithography we've ever seen.
Scientists have no problem with this, of course. It was discovered that when exposed to oxygen, the photosensitive resin quickly solidified. Because of this, the photosensitive resin must be free of oxygen. The curing process comes to an end when a small amount of oxygen is dissolved. Generally speaking, oxygen is a 3D printer's archenemy. It's for this reason that oxygen molecules are inserted between the processing layer and the platform, which prevents the printing layer from adhering to the platform, allowing it to move up and down freely.
From the foregoing description, it is clear to see that the volume of pieces and the ability to find suitable materials are the main obstacles to 3D printing. Simply because each product's basic components and photosensitive resin have different chemical structures, a custom synthesis procedure is needed to make them work together. So, 3D printing is out of reach for many clients due to the high cost of the printers on the market. As a result, the low cost of 3D printing may not be as low as previously predicted. In addition to extrusion molding, scientists have also developed various 3D printing methods, such as fused deposition molding (FDM), which is based on this idea.
