A 3D printed object is the result of an additive process in which successive layers of material are added to form the final shape. This contrasts with subtractive manufacturing methods, which involve removing excess material before cutting out the final design.
Hideo Kodama of the Nagoya Municipal Industrial Research Institute created the first 3D printing manufacturing equipment with his invention of two additive methods for creating 3D models.
3D printing appears to be a greener production option than traditional subtractive processes. Sintering, melting, and stereolithography are the three main categories of 3D printing techniques.
3D Printers’ Advantages
The use of 3D printers has benefits and drawbacks. Thus, it is prudent to weigh the benefits first. With 3D printing, it’s feasible to make objects that would be hard to make with more conventional methods of production. With the help of 3D printing, you can give your thoughts a physical form.
1. Less Time Consuming
Since the advent of 3D printing, new concepts may be developed at a breakneck pace. In order to keep ahead of the competition, users can benefit from the ability to 3D print concepts on the same day they are designed, cutting down the development time from days to hours.
2. Expense Reductions
Investments in prototyping equipment and trial production runs might be substantial. Additive manufacturing, made possible by 3D printing, enables the rapid production of parts and tools at significantly cheaper costs than conventional machining.
3. Successes in New Heights of Innovation
A wide variety of innovative endeavors, from new courses to cross-disciplinary efforts to cutting-edge research, may be made possible by 3D printing. Thanks to the possibilities presented by 3D printing technology, many firms have already emerged on campus.
3D Printers’ Disadvantages
Every technology or innovation comes with pros and cons. So let’s check out what are the negatives of 3D printing.
1. Limited Production
When time is of the essence, and you need many components quickly, 3D printing is not the best option. The final cost of 3D printing is higher than the first estimate because the initial costs are never reduced.
2. Toxic Fumes
Fumes from 3D printing can be harmful since the filament used in the process is poisonous. Mainly, when ABS, PETG, or Nylon filaments are melted, particles are released that might irritate the eyes and nose and cause headaches and nausea.
However, this problem can be fixed by following the proper measures, such as Enclosures and Air filtering solutions for 3D Printers. In order to provide safety to our environment and those who use 3D printers need to use filter technologies for 3d printers.
3. Copyright Claims
People who plan on making a living off of selling 3D prints need to be especially aware of copyright concerns. Disney is a worldwide icon loved by people of all ages. Perhaps you’ll have the brilliant idea of 3D printing your personalized set of Mickey’s ears to wear on your Disney World vacation.
In case somebody takes note of your unique ears, you may get a request to sell them. After agreeing, you simply print off another set and send them out.
4. Printing Standards
There is a significant difference between various 3D printers. Low-cost 3D printers can’t compete with more expensive models since they lack the necessary technologies. Therefore, every time you use a low-cost 3D printer, you run the danger of producing flawed prints.
The calibration of 3D printers requires extreme precision. The nozzle gets hot enough, knows where to deposit thermoplastics, and the heating bed is warm enough to attach plastic to it but not so warm that plastic cools too rapidly; all of these factors work together in unison.
3D printing is a revolution when it comes to creativity. But the dangerous aspect of 3d printing is its effect on the environment. Many studies have proved it, and therefore we should look for some serious and immediate solutions to minimize its impact.
