bcbMonitor - Additive manufacturing

Controlling the temperature to ensure the quality of the final product.

Additive manufacturing, also known as 3D printing, allows you to create parts directly from a digital model without the need for traditional subtractive machining tools and with minimal geometry limitations.

Laser sintering uses a high power laser to melt fine metallic powder and create functional parts with complex 3-dimensional geometries. In the case of plastic parts, the manufacture is carried out by deposition of molten material in successive layers.

Heat is an integral part of the additive manufacturing process and needs to be monitored to detect phenomena that have a direct effect on the quality and performance, both dimensional and mechanical, of the final product. Diagnosing heat stress or distortions using typical contact sensors such as thermocouples, RTDs, or thermistors, is difficult or even impossible. Thermal imaging cameras can help manufacturing engineers study the process and its thermal properties, correlating temperatures measured during the process with quality parameters of the finished product.

With the help of thermography, porosities, delaminations, shrinkage, poor surface finishes or dimensional defects can be identified.
