| RepRap 3D print engineers Michael Simpson and Simon Khoury recently conducted a scientific study of bed surface smoothing and nozzle contact detection using inexpensive piezoelectric elements in FDM / FFF 3D printers, and found that these elements are effective even at high temperatures .  RepRap 3D printers and other low-cost FDM 3D printers are among the core and soul of the manufacturer community and one of the biggest reasons for the consumer 3D printing boom in recent years, but these 3D printers have their limitations: from cheap components and 3D printing components The technology means that the factory-produced 3D printer may lose some of the more luxurious features or at least be functionally limited. One such feature is print leveling, and while building platform auto-leveling is now common in lower-end FDM 3D printers, building your own leveling system remains a challenge for many RepRap users. There are many ways you can For example, the Ultimaker 3 uses the capacitance detection method, and the Lulzbot 3D printer uses the electrical contact method. The Prusa i3 is one of the best-known RepRaps and uses an inductive probe. Another solution to the problem of print bed leveling is to use cheap piezoelectric diaphragms that can be used as sensors for this task and to adjust nozzle heights, but can they guarantee reliable, complex 3D printing? Two RepRap experts from the UK, Michael Simpson and Simon Khoury, seem to think so too, and they have just used the separators to conduct scientific research on FDM / FFF 3D printers and as a result have found very promising. During the experiment, Simpson and Khoury tested the samples for more than 100,000 cycles at 20 ° C and 80 ° C and found that the output loss of the components was small, even at higher temperatures. , 'Piezoelectric diaphragms have useful levels of reliability, sensitivity and repeatability', and these components are expected to have a 'long life' profile.
