“…It was noticed that higher density specimens can be kept inside the vapour chamber for a prolonged time without undergoing part deformation. With the variation of input parameters considered in this research (volume, temperature, and time or concentration) there is significant variability in surface finish compared to the parameters taken into in [33]. But, both the processes with the optimised configuration parameters produced similar levels of surface finish for all specimens after the CVS process.…”

“…As stated in [29], it was observed that prolonged exposure of the specimen to the CVS system led to improved surface finish outcomes. As mentioned in [33], it was observed that part density plays a major role in the hot vapour polishing process for getting better surface finish results. It was noticed that higher density specimens can be kept inside the vapour chamber for a prolonged time without undergoing part deformation.…”

“…Chemical vapour smoothening (CVS) was used to enhance the surface smoothness of FDM-based ABS models in [31]. During the analysis in various research works, it was discovered that the model's build orientation, raster orientation [32] temperature [33], road width, air gap, and layer thickness were all key contributors to surface roughness and various mechanical properties (fatigue life [32], residual stress [34]). The parameters derived out from modal analysis and the vibration response are most significantly impacted by the type of adhesion [35].…”

Fused deposition modelling (FDM) is a process of layer-by-layer material deposition using a heated extruder. FDM printed parts have stair-stepped effect and ridge patterns that diminish surface quality. This research intends to develop a low-cost, high-efficiency experimental system for polishing a variety of materials using various chemicals, with a chemical vapour smoothening process. For evaluating the created set-up, tetrahydrofuran (THF) is used and acetone as solvents to polish polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS). Taguchi multiparameter optimization was used to optimize the input parameters (reagent volume, temperature, concentration, and time) in the vapour smoothening process. With the ideal input parameters, the roughness of the FDM printed parts was reduced by over 95%. The effectiveness of a vapour smoothening system is better when the system temperature is maintained at the boiling point of the reagent, the reagent is of its highest concentration, and when the specimens placed are placed directly over the ultrasonic mist-maker. The system discussed works best with FDM printed parts having minimum porosity and better quality. The hot chemical vapour smoothing approach reduced specimen flexural strength and increased top layer wear. The findings of this study will help develop a large-scale polishing system for FDM printed thermoplastics and enhance the use of FDM components in sectors that need highly polished parts.

“…These are made by heating a polymer to its melting point and then manipulating it to the desired shape. The consistent heat allows the polymer to stay in liquid form long enough for the composite to be shaped [54,58]. These composites can be used in many different ways such as cladding for walls or plastics that are nonbiodegradble or biodegradable depending on the application.…”

In this review, the potential failures and flaws associated with fused deposition modeling (FDM) or fused filament fabrication (FFF) 3D printing technology are highlighted. The focus of this article is on presenting the failures and flaws that are caused by the operational standpoints and which are based on the many years of experience with current and emerging materials and equipment for the 3D printing of polymers and composites using the FDM/FFF method. FDM or FFF 3D printing, which is also known as an additive manufacturing (AM) technique, is a material processing and fabrication method where the raw material, usually in the form of filaments, is added layer-by-layer to create a three-dimensional part from a computer designed model. As expected, there are many advantages in terms of material usage, fabrication time, the complexity of the part, and the ease of use in FDM/FFF, which are extensively discussed in many articles. However, to upgrade the application of this technology from public general usage and prototyping to large-scale production use, as well as to be certain about the integrity of the parts even in a prototype, the quality and structural properties of the products become a big concern. This study provides discussions and insights into the potential factors that can cause the failure of 3D printers when producing a part and presents the type and characteristics of potential flaws that can happen in the produced parts. Common defects posed by FDM printing have been discussed, and common nondestructive detection methods to identify these flaws both in-process and after the process is completed are discussed. The discussions on the failures and flaws in machines provides useful information on troubleshooting the process if they happen, and the review on the failures and flaws in parts helps researchers and operators learn about the causes and effects of the flaws in a practical way.

“…The advantages of additive manufacturing include lower material costs, the ability to customise components, and the ability to produce in various ways [ 13 ]. Life cycle analysis was used to evaluate the environmental effect of two distinct additive manufacturing machines (fused deposition modelling and polyjet) on that of a regular computer numerical control (CNC) milling machine using a life cycle analysis model (CNC milling machine) [ 14 , 15 ]. According to the literature, the fused deposition modelling machine had the lowest environmental impact per component created [ 16 , 17 ].…”

According to research findings of many peer-reviewed studies, up to 90% of household items may be made of plastic. But nowadays, just a small portion of plastic waste is recycled. Plastic pyrolysis and polymer breakdown are environmentally hazardous. Processing is, therefore, necessary for recycling. Plastics are constantly being manufactured and require minimal processing, necessitating innovation. Plastic recycling is becoming a major issue for environmentalists and waste management professionals. Fused deposition modelling, or FDM, is one of the most popular types of additive manufacturing. It uses the melt extrusion process to deposit filaments of thermal polymers in a predetermined pattern. Using a computer-generated design, 3D printing, sometimes referred to as additive manufacturing, is a technique for building three-dimensional objects layer by layer. A 3D item is produced by the additive method of 3D printing, which involves building up layers of material. To make a three-dimensional object, FDM printers eject a thermoplastic filament that has been heated to its melting point layer by layer. 3D printing is a rapidly expanding industry and the market in this field has grown up to 23% by 2021. Several experiments on new 3D printing materials have been carried out to reduce pollution and the supply of plastic. Various additives have been investigated to increase recycled polymers’ molecular weight and mechanical properties. The most frequent type of fibre found in that is thermoplastic fibre. In this instance, waste ABS (acrylonitrile butadiene styrene) plastic from industrial FDM printers was gathered and examined in a bustling open shop. In this review, we discussed the use of recyclable polymers in 3D printing for waste material management. Graphical abstract
