“…Moreover, the problem is caused by force transmission between the first layer and other layers owing to the phase of change from molten plastic to solid during the building process. Some of the examples of warping deformation problems which occur in the FDM 3D process are pincushion, trapezoid, curling and blocked shrinkages [1]. Figure 6 shows the original CAD file of the FDM 3D printed part target for warping analysis.…”

“…Worldwide, in modern manufacturing industries, the attention to maximizing productivity has been one of the set performance targets for an extended period [1]. In order to achieve higher printing quality products with suitability for market applications, greater efficiency and direct reduction of costs, as well as an ability to comply with environmental requirements along with a subsequently faster new product development process and quicker span timeline to the client, modern manufacturing industries have endeavored to apply more computerintegrated automation systems (i.e., which encompasses time investment in learning the software and hardware) [2].…”

This paper experimentally observed at a small level the influence of nozzle temperature change on warping deformation (WD), dimensional Accuracy (DA) and density. The materials chosen are pure PLA and advanced PLA+ specimens of rectangular shape of 63.5 mm × 9.53 mm × 3.2 mm produced by the end-user 3D printer based on fused deposition modeling (FDM). During the printing work, the nozzle temperature was conducted at twelve different values 195°C to 250°C with 5°C increments. Additionally, the infill density was set at 20% along with infill line direction of 0°, 90°, 45° and ±45°. After the fabrication, the FDM 3D printed parts naturally cooled down to room temperature at T = 23±2°C. As a result, the higher the nozzle temperature, the lower the deformed shape errors (with low uncertainty) of the specimens were. Experimental results show that the measured dimensions are always more than the original CAD file dimension along the height but less than the original CAD file dimensions along the width and length. The density measurements of both materials at 90° infill line direction have higher values compared with other directions (0°, 45°, ±45°), which have very similar results. The data and knowledge obtained from this investigation can be helpful for both an academic and an industrial perspective to set optimum nozzle temperature at small scale level and also it can be used to fabricate low-cost functional objects. Furthermore, it will also allow us to redesign the original CAD file in order to compensate the warping deformation encountered when using end-user FDM 3D additive manufacturing.

“…The effectiveness of ironing on reducing the levels of distortion decreases when ironing is applied on the second or third layers. The positive effect of ironing on the reduction of warping of ABS plates can be related with an increase of adhesion between layers and the printer platform (through the reduction of internal stresses), induced by the thermal energy delivered during the ironing process 18,19,22,23 …”

In this work, the effect of a thermal process termed ironing on the superficial, mechanical, and dimensional properties of Acrylonitrile Butadiene Styrene (ABS) parts produced by fused deposition modelling (FDM) is evaluated. Three sets of samples for each studied parameter were manufactured. Cubic samples were used to evaluate the influence of the process in the average surface roughness (Ra) of top layers. Prismatic beams and plates were chosen to evaluate the interlaminar strength (ILS) and warping of parts, respectively. A Python script was developed to enhance the applicability of process. Although ironing may influence the thermal behaviour of deposited layers, it was not effective in enhancing the ILS of parts, due to the generation of geometric irregularities. The results show that ironing can reduce the Ra of ABS parts up to 60% and distortion levels by 33%. The study suggests ironing as an alternative postprocessing technique for FDM parts.

“…The influence of the build plate temperature is not examined, which is a field of further investigations. In NAZAN et al [74], the influences of an improved connection of the component to the building platform by means of epoxy resin are also examined on the basis of the resulting distortion. It is determined that the different materials have different warpage tendencies, but PLA has the smallest deviations with an unheated construction platform.…”

Additive manufacturing has become a very important manufacturing method in the last years. With additive manufacturing, a higher level of function integration can be achieved compared to traditional manufacturing technologies. However, the manufacturing of larger parts leads to long construction times. A possible solution is the combination of multipoint moulding with additive manufactured form elements. This article reviews the state of technology for multipoint moulding and additive manufacturing. Moreover, the state of technology is analysed to outline the possibilities and challenges of combining both technologies. The review shows that there has been research on different challenges of the new production process. On the other hand, it turns out clearly that there are many open points at the intersections of both technologies. Finally, the areas where further research is necessary are described in detail.
