The greatest advantage of SLM 3D printers in medical applications is the freedom to produce custom-made medical products and equipment such as custom-made implants, guides, and surgical tools. Another important benefit offered by 3D printing is the ability to produce items cheaply. The cost of 3D printing is becoming more and more competitive for small production runs. This is especially true for small-sized standard implants or prosthetics, such as those used for spinal, dental, or craniofacial disorders. We should add short lead time to the advantages of SLM process which is important especially in trauma patient cases.
