The best materials to choose for medical equipment include titanium and stainless steel, which are both highly biocompatible and non-toxic to the human body. Additionally, plastic polymers such as PE, PP, and PU can be used for many medical applications.

Medical instruments such as scissors, cutting knives, tweezers, and brackets must be easy to sterilize in order to prevent infection. This is why they need to be manufactured with very high levels of precision and surface finish, and are therefore ideal candidates for CNC machining. In particular, CNC Swiss machining is an excellent option for these types of medical tools, as it produces extremely accurate and repeatable parts at a very low cost.
Flexibility

As medical devices become smaller and more complex, it is becoming increasingly important for machinists to use a wide range of machining techniques. Choosing a shop that offers a variety of CNC machines and is capable of handling multiple processes, including turning, milling, boring and knurling, deep hole drilling, gear hobbing, and threading, is essential for medical engineers to get parts out the door quickly and accurately.

Many of the medical prototypes that are machined require tight tolerances due to their size and because they work with bodily tissue. These tolerances are often difficult to meet using injection molding or other production methods. Moreover, these production processes are costly and time-consuming compared to the quick turnarounds that precision CNC machining provides.

To ensure the quality of medical devices, it is crucial to choose a manufacturing partner that complies with industry standards and regulations. This includes being ISO 13485 and 9001 certified and providing a detailed Quality Control system. Additionally, a manufacturer should have the ability to handle the design, prototyping, testing and characterization of medical devices, as well as their manufacturing and assembly.

DDPROTOTYPE utilizes multiple CNC Swiss machining lathes to produce high-quality medical parts with a short lead time. These CNC machines are capable of rotating parts on more than 7 axes, ensuring precise cuts and tolerances.
