In the twenty-first century, it is almost inarguable that the invention to single-handedly contribute the most to innovation across multiple industries will be the 3D printer. Although it is still in its infancy stages as a technology, it has already shown immense promise in its capabilities. Gun specialists have already built computer designs that allow them to “print” an entire weapon from scratch. Medical specialists have been able to print off durable limb replacements that are used for patients who have had to undergo a recent amputation. Engineers are able to print off any spare parts that they are missing, allowing their design process to proceed in a more efficient manner. Of course, it goes without saying that 3D printing materials must be chosen carefully based on the objective of a given printing job. This article will briefly explain how choosing the right materials influences the end product of a 3D print job, and provide real-life examples to show how material selection makes a big difference.
Why Does Choosing the Right Materials Matter?
The material that one chooses for a 3D printing job matters because it influences everything, from the time and difficulty of printing the object to its usefulness for the consumer. While something like plastic will print faster than a metal-based material given an equal design, it will not be as durable upon completion and will break more easily upon heavy-duty use. Likewise, a 3D-printed metal object can withstand rougher conditions and use, but will take a much longer time to print due to the process of welding the metal together in the dimensions specified by the printing software. While there are no “bad” materials when it comes to 3D printing, experts still recognize that there are better materials that should be used for a given print job when considering its end purpose.
What Are Some Examples?
3D printing materials see a wide range of applications in a diverse group of industries. For example, plastic-based materials are most often used when it comes to printing figurines and spare parts for industrial products. Due to their quick turnover through a faster 3D printing speed, they are starting to see big applications in reducing costs within the manufacturing process. When it comes to the design of artificial limbs, lightweight and non-magnetic metals are employed. These take longer to print due to the nature of the metal and the increased complexity of design within the limb. However, that extra time is justified, as these limbs are being built to be used by patients for several years. It is obvious to anybody working with 3D printing technology that the material being used depends entirely on what the printed product will be used for. This is why it is important to have multiple 3D printing materials on hand, while being able to switch between them when working on different jobs.
