Fluke thermal imaging camera tells you how to control the 3D printing process

In the 3D printing process, due to the different characteristics of speed, distance, material, etc., during the process of stacking the powder layer by layer, the temperature will be abnormal, such as jumping, too high, too low, uneven, etc., resulting in the structure after printing. The performance of the parts is reduced, the toughness is poor, the elasticity is not enough, the brittleness, the hidden lines, and the like. Use the Master's Choice Series Thermal Imager to provide an effective inspection solution for metal printing.

Applications:

The State Key Laboratory of Mechanical Manufacturing Systems Engineering at a university is responsible for the rapid and accurate production of parts of any complex shape using 3D printing technology , thus enabling the “free manufacturing” project. In the 3D metal printing process, metal powder is not used as raw material to print parts of any shape, and the temperature of the structural parts and the temperature change trend have a key influence on the characteristics of the metal structural parts. Temperature control is an important factor in the printing process.

TiX1000+ macro lens 3 is detected 90 cm away from the target

Technical Difficulties:

1. Some materials have small targets: When starting printing, the target size may be small. In the case, only 2-3mm is needed and the temperature distribution of the material surface and the temperature change process need to be seen clearly. A macro lens is required to clearly see the temperature distribution of the material surface. At the same time, due to the needs of processing equipment and the need for processing safety, the shooting distance may need to be farther, and a lens with a macro of 3 is required.

2, material printing speed: 1-2s time period, you need to go through the length of 3mm stroke, so choose 60Hz frame rate and above the frame rate is best.

3, high temperature: the temperature of the material may be 1800 degrees, you need to choose the high temperature option (60Hz or higher frame rate, you need to cooperate with online analysis software).

4, need to monitor the real-time temperature during the printing process: some sites need to print the temperature change state of the surface in real time, and the temperature data, draw the temperature curve, confirm the process temperature of the new material.

Industry application:

University research institutes in the fields of jewellery, industrial design, construction, automotive, aerospace, dental and medical industries, as well as research and development production units.

Vacuum Coffee Mug

Stainless Steel Coffee Mugs are made from high-grade 18/8 stainless steel. This material is food grade, non-toxic, durable and easy to clean.

Our Stainless Steel Bottles are mostly Stainless Steel Vacuum Coffee Mugs. They have a double-wall vacuum treatment, so they can ensure your drink keeps as it is. And you don't need to worry about getting your hands cold or hot.

Stainless Steel Single Coffee Mug has a single wall. It sacrifices thermal insulation and improves portability. Holding it in your hand all the time will not cause any discomfort.
