“…The results showed that the surface roughness was improved by increasing the lapping time, and the anisotropic nature of FDM parts was converted into an isotropic nature without any changes in the flexural strength of FDM parts. Liu et al (2022) have proposed a novel surface finishing technique using electrorheological (ER) fluid-assisted ultrasonic polishing to enhance the surface quality of metal AM parts. The results showed that the initial surface roughness of 5.6 µm was improved up to 2.74 µm with an 11% improvement using ER effect.…”

Purpose The purpose of this paper is to study the functionality of additively manufactured (AM) parts, mainly depending on their dimensional accuracy and surface finish. However, the products manufactured using AM usually suffer from defects like roughness or uneven surfaces. This paper discusses the various surface quality improvement techniques, including how to reduce surface defects, surface roughness and dimensional accuracy of AM parts. Design/methodology/approach There are many different types of popular AM methods. Unfortunately, these AM methods are susceptible to different kinds of surface defects in the product. As a result, pre- and postprocessing efforts and control of various AM process parameters are needed to improve the surface quality and reduce surface roughness. Findings In this paper, the various surface quality improvement methods are categorized based on the type of materials, working principles of AM and types of finishing processes. They have been divided into chemical, thermal, mechanical and hybrid-based categories. Research limitations/implications The review has evaluated the possibility of various surface finishing methods for enhancing the surface quality of AM parts. It has also discussed the research perspective of these methods for surface finishing of AM parts at micro- to nanolevel surface roughness and better dimensional accuracy. Originality/value This paper represents a comprehensive review of surface quality improvement methods for both metals and polymer-based AM parts.

“…In addition, ER polishing was also combined with other polishing techniques to achieve a more efficient finishing. For example, Liu et al used the ER effect to assist ultrasonic polishing in 2022 [ 20 ]. The polishing particles were better concentrated in the polished area with the assistance of ER fluid in the circumstances.…”

Electrorheological (ER) polishing is a novel polishing technology having flexible and tunable characteristics. At present, ER polishing uses ER particles to drive abrasive particles to polish the material surface. Under the action of high-speed centrifugation, the abrasive particles are easily separated from ER particles due to their significantly different ER effect, and this can easily cause the degradation of polishing ability. In this work, alumina-doped titanium dioxide ER polishing particles were developed via a sol-gel method. As a classical abrasive, alumina has higher hardness and can improve the ER effect of titanium dioxide by doping. Thus, alumina-doped titanium dioxide particles simultaneously possess high ER effect and high hardness. No phase separation appears in the polishing process and the result shows that alumina-doped titanium dioxide has a good polishing efficiency for materials with Mohs hardness of 3 and below.

“…Tateishi et al (2009) reported an ER fluid-assisted ultrasonic polishing method that could effectively reduce debris generation during ultrasonic vibration processing micro vias. Liu et al (2022) processed selective laser melting (SLM) IN625 specimens using ER fluid-assisted ultrasonic polishing. The high efficiency and high precision surface treatment of complex metal surfaces for Additive manufacturing (AM) is realized.…”

Electrorheological polishing (ERP) is an important field-assisted polishing method, which can reduce abrasive loss and improve machining efficiency by using the electric field-induced electrorheological (ER) effect to help the abrasive to overcome the centrifugal force caused by high rotating speed during polishing. ERP has many advantages, including high efficiency, high precision, facile polishing for a small object, and a good application prospect in polishing optical devices and hard molds. This review describes the research progress in ERP in the past two decades. The mechanism of electrorheological polishing is analyzed from two aspects of electrorheological effect and dielectrophoresis. According to the time sequence of electrorheological polishing development, two kinds of ERP materials including the simple mixing system and composite particle system are introduced. ERP electrodes including off-axis bipolar electrode, needle-ring electrode, needle-like single electrode, one-sided patterned electrode, and one-sided simple composite electrode are described. From the two characterization quantities of removal rate and surface quality, the industrial factors affecting the ERP effect are discussed. The advantages and disadvantages of ERP and other polishing processes are compared. Finally, the remaining challenges and possible development trends in ERP technology for the future outlook are proposed.
