Medical device manufacturers are now able to 3D print complex products with intricate internal structures. In particular, 3d-printed orthopaedic implants are being designed with porous surfaces and complex internal geometries to facilitate faster integration between living bone and the artificial implant. However, when the printer deposits the material during the additive manufacturing process, there is potential for imperfections. Types of materials are also a consideration. How does the manufacturer verify the accuracy and integrity of these parts without destroying them? How do they answer questions about porosity or fine tune their printing process? 3D scanning services in the form of industrial computed tomography (CT) is the only solution. The accuracy and resolution of CT makes it the perfect fit for these multifarious, 3D printed medical implants.
NPC utilizes the Zeiss Metrotom 800 and 1500 computed tomography (CT) scanning systems which project a beam of x-rays onto the object in order to obtain a 3D data set. This 3D scanning system allows the user to examine the interior and exterior components. It is valuable insight for various job functions within the additive manufacturer's organization. Information from the scan can be compared to the CAD model, other parts, or other data sets. If the data is used properly, it can lead to fewer iterations of change in the 3D printing process allowing for shorter production schedules.
Our 3d scanning and CT specialists understand the science behind x-rays, how they behave, and how they interact with parts of different material types and densities. It is not just about the ability to perform a scan, but rather the skill in interpreting the scan data using specialized analysis software as well. Our specialists also understand statistical variability and data trends. This is key when performing final data analysis.
With critical, high quality, time sensitive parts in the medical manufacturing industry, x-ray technology is employed to shorten the time it takes to get products to market. Common uses for 3D scanning technology are:
For additive manufacturing, 3D scanning is applied to:
In addition, there is software available to conduct foam structure analysis, a contemporary biomedical solution. All of this can be accomplished with one scan or in other words, one set of data.
