Mastering the Temperature of the Bothend: Optimizing 3D Print with PID on Anet Et4 Plus and PLA+

Introduction

3D printing technology has revolutionized the engineering world with its ability to realize various designs into a three-dimensional visual form. However, the stability of the temperature in 3D printing has a significant impact on the quality of print products. Good temperature control produces more optimal printed quality than before. This study aims to condition the temperature of the bothend on the 3D Anet et4 plus printing machine using PID control (proportional, integral, and derivative) with PLA+ filament, which has a slightly better strength than a standard PLA filament.

The Importance of PID Control

PID is a control algorithm that is widely used in an automatic setting system. On a 3D printing machine, PID works by adjusting the temperature of the bothend to remain consistent with the desired target. PID uses three main parameters:

*** Proportional (P): ** This parameter responds to the current error between the target temperature and the actual temperature. The greater the P value, the faster the system responds to temperature changes. *** Integral (I): ** This parameter takes into account a cumulative error from time to time. Parameter I helps remove long-term offset. *** Derivative (D): ** This parameter takes into account the rate of change in temperature. Parameters D help reduce oscillation or temperature fluctuations.

By regulating these three parameters correctly, PID control can keep the temperature of the bothend stable and consistent, so as to produce better and more consistent mold quality.

Benefits of Using PLA+

PLA+ offers several advantages compared to standard PLA:

*** Strength: ** PLA+ has a better tensile strength and impact, making it more durable and less fragile. *** Hot resistance: ** PLA+ has a higher melting point, making it more resistant to high temperatures during the printing process. *** Ease of printing: ** PLA+ is generally easy to print with standard printing settings and has a good adhesion on the print base.

Research Methodology

This study uses the MKS Gen-L V2.1 to activate the implementation of PID control on a 3D printing machine, which is then compared to the performance of the printing machine without PID control. The method used is ANOVA (analysis of variance) with univariate one-way analysis of variance.

Research Result

This study is expected to show that PID control can increase the temperature stability of the bothend on the 3D Anet Et4 Plus printing machine. The results of the study will be analyzed using the ANOVA method to compare the quality of the mold with and without PID control. The results of this study will provide valuable information about the importance of appropriate temperature control in 3D printing using PLA+ filament.

Conclusion

PID settings on 3D printing machines are important steps to improve the quality of molds by ensuring the stability of the bothend temperature. Proper PID regulation can minimize temperature variations and produce smoother, more detailed, and more consistent printouts. The use of PLA+ filament which has advantages compared to standard PLA also provides an important contribution in improving the quality of molds.

Practical Guidelines

This research is expected to provide practical guidelines for 3D printing machine users in optimizing PID settings and choosing the right type of filament to get the best printed results. By understanding the importance of PID control and the benefits of using PLA+ filament, users can improve the quality of their prints and achieve better results in their 3D printing projects.

Future Research Directions

Future research can focus on exploring other types of filaments and their properties, as well as developing more advanced PID control algorithms to improve the stability and consistency of 3D printing. Additionally, research can be conducted on the effects of PID control on other aspects of 3D printing, such as print speed and layer adhesion.
