“…Suder et al reported that the tensile strength of PLA increased with increasing annealing temperature, with a maximum increase at 100 °C; however, as the annealing temperature went above 100 °C, the tensile strength decreased and was even lower compared with the non-annealed samples. 42 The samples in this study were all annealed at 160 °C to maximize crystallization and nucleation of SC. The data collected from the trials mentioned above supported the annealing temperature chosen.…”

“…For each object, a housing was created to hold the sensors in a defined position, as shown in Figure 8b-d. The housings were made by an additive manufacturing technique using PLA material, which is commonly used and has very good mechanical properties [29]. The housings were attached to an aluminum matrix with threaded holes, so their position relative to the robot base was known.…”

In this paper, we examine a method for improving pose estimation by correctly positioning the sensors relative to the scanned object. Three objects made of different materials and using different manufacturing technologies were selected for the experiment. To collect input data for orientation estimation, a simulation environment was created where each object was scanned at different poses. A simulation model of the laser line triangulation sensor was created for scanning, and the optical surface properties of the scanned objects were set to simulate real scanning conditions. The simulation was verified on a real system using the UR10e robot to rotate and move the object. The presented results show that the simulation matches the real measurements and that the appropriate placement of the sensors has improved the orientation estimation.

“…The annealed samples were two sets, one annealed at 80 °C and the other at 100 °C. These temperatures were selected according to the work [Suder 2020], which dealt with the annealing of these materials. The temperature was maintained for 30 minutes, and then the samples were removed from the oven, where they were slowly cooled to room temperature.…”

“…On the topic of PLA parts' behaviour at higher temperatures, some studies have already been performed, which describe mainly the increase of heat deflection temperature after annealing [Rigid 2017, Koci 2019, Feeney 2019. PLA annealing is a known heat treatment process in which the internal stress of the material caused by production on a 3D printer is minimized, and thus higher strength of printed parts is achieved [Suder 2020]. However, our own experience with these materials in the annealing process contradicts some claims published in temperature resistance studies of annealed plastics [Feeney 2019], where it is stated that the material begins to soften due to annealing about 170 °C.…”
