Additive manufacturing has been applied in many fields, but its layer-by-layer fabrication process leads to a weak inter-layer bond strength of printed parts, so it cannot meet the higher requirements for mechanical properties of the industry. At present, many researchers are studying the printing path planning method to improve the mechanical properties of printed parts. This paper proposes a method to plan the printing path according to the actual stress of pipe parts, and introduces the realization process of an algorithm in detail, and obtains the printing control G-code. Additionally, a 5-axis material extrusion platform was built to realize the printing of polylactic acid pipes with plane and space skeleton curves, respectively, which verified the feasibility and applicability of the method and the correctness of the planning path with standard material extrusion filaments. Finally, the tensile and bending experiments prove that axial printing enhances the mechanical properties of pipe parts.

Abstract Cooperative 3D printing (C3DP) is a novel approach to additive manufacturing, where multiple mobile 3D printing robots work together cooperatively to print the desired part. At the core of C3DP lies the chunk-based printing strategy. This strategy splits the desired part into smaller chunks, and then the chunks are assigned and scheduled to be printed by individual printing robots. In our previous work, we presented various hardware and software components of C3DP, such as mobile 3D printers, chunk-based slicing, scheduling, and simulation. In this study, we present a fully integrated and functional C3DP platform with all necessary components, including chunker, slicer, scheduler, printing robots, build floor, and outline how they work in unison from a system-level perspective. To realize C3DP, new developments of both hardware and software are presented, including new chunking approaches, scalable scheduler for multiple robots, SCARA-based printing robots, a mobile platform for transporting printing robots, modular floor tiles, and a charging station for the mobile platform. Finally, we demonstrate the capability of the system using two case studies. In these demonstrations, a CAD model of a part is fed to the chunker, divided into smaller chunks, passed to the scheduler, and assigned and scheduled to be printed by the scheduler with a given number of robots. The slicer generates G-code for each of the chunks and combines G-code into one file for each robot. The simulator then uses the G-code generated by the slicer to generate animations for visualization purposes.

<p>Teknologi FDM (<em>Fused Deposition Modelling</em>) merupakan salah satu teknologi yang digunakan untuk membuat objek 3D. FDM sering disebut sebagai teknologi yang sudah mampu mengubah dunia manufaktur dewasa ini. Namun teknologi FDM memiliki kelemahan karena teknologi ini menggunakan proses <em>building per layer </em>membuat permukaan yang dihasilkan terlihat memiliki garis yang menunjukan batas antar <em>layer </em>sehingga mempengaruhi kekasaran pada permukaan produk cetak.  Penelitian ini menggunakan filamen <em>Super Tough</em> PLA (ST.PLA). Tujuan penelitian ini adalah untuk mengetahui pengaruh parameter proses terhadap kekasaran permukaan objek cetak dan untuk mengetahui seting parameter proses yang menghasilkan kekasaran permukaan terbaik dari parameter proses yang digunakan. Penelitian ini menggunakan metode Taguchi dengan matriks ortogonal L<sub>25</sub>(5<sup>6</sup>).  Parameter proses yang akan dipilih dan dianalisis dalam penelitian ini adalah<em> layer thickness, printing speed, nozzle temperature, orientation, flowrate</em>, <em>cooling speed </em>dan respon yang diamati adalah kekasaran permukaan objek cetak. Untuk mengatasi permasalahan <em>noise</em> (gangguan) maka dicetak masing-masing tiga kali replikasi  Selanjutnya parameter proses tersebut akan dianalisis menggunakan Analisis Varian (ANOVA). Berdasarkan data  hasil pengukuran kekasaran permukaaan objek cetak,  maka diperoleh parameter proses yang memberikan pengaruh paling besar terhadap kekasaran permukaan objek cetak dengan menggunakan filamen ST-PLA adalah <em>layer thickness</em> dengan nilai F hitung sebesar 129,96, <em>flowrate</em> dengan nilai F hitung sebesar 6 dan <em>orientation</em> dengan nilai F hitung sebesar 3,03.

The work deals with the investigation of the variation of the selected 3D printing process properties that originate from the choice of a slicer. Specifically, the main aim of the present study was to assess the induced changes of the kinematic and geometric properties considered by the slicer for the printing process making use of the G-code readings. The paper provides adequate definitions and formulas required to characterize the slicer’s configuration. Next, the selected cases of the process parameters’ changes were studied, primarily taking into account varying layer height and infill. The authors performed a detailed analysis regarding the geometric implications at the mesoscale due to the slicer’s settings. Appropriate modifications of the slicer’s properties were also proposed and verified, making it possible to match the geometric and kinematic characteristics of the printed part.
