Selective laser sintering, selective laser melting or colorjet; they are a number of ways of 3D printing and additive manufacturing. The common factor that all these methods have is that they work with powders or plastics that they process into a rapid prototype.

Sensor for level measurement

But how do you know the powder or liquid level in the printer or additive? Rechner Sensors has the solution with capacitive sensors that can excellently detect the conductive powders and sticky liquids.

Accurate detection of additives

The powders, liquids or pastes used range from metal and metal alloys to plastics such as ABS, PLA, nylon, PET, PP and ceramics or sand. The accurate detection of these additives is a must for the machines to function optimally and to obtain the desired end result from the printed part.

Fixed switch point or constant measurement

This is a perfect task for capacitive sensors with a switching or analog output with which a min-max level or constant measurement can be performed.

A contaminated sensor that keeps measuring accurately

The capacitive sensors from Rechner Sensors have media optimization technology. This technique ensures that sticky or conductive additives that stick to a sensor do not affect the accuracy of the measurement. The sensor calibrates itself when these additives permanently cover the sensor.

Use of different additives

This also makes the sensors extremely suitable when different types of additives are used alternately in one printer. In addition, many of the capacitive sensors from Rechner Sensors are certified for use in ATEX zones. This makes it possible to use highly flammable powders or liquids.

A suitable sensor is available for each size 3D printer. Models range from M12 to M32 and G1 / 2 "and G1" formats. The capacitive sensors for 3D printing are the ideal solution for accurately detecting additives.
