Implementation of Using Collaborative Robots in the Additive Manufacturing Process

2023

This paper focuses on a topic that is frequently used nowadays namely 3D printing. The term 3D printing encompasses several manufacturing technologies that build parts layer-by-layer an inconvenience of this process is that the deposition of material takes place in the plane (2D space) then by applying a constant increment on the third axis it is moved to the next plane. The deposition of material is taking part in a 2D space. There are many types of 3D printing such as FDM (fused deposition modeling), SLA (stereolitography), SLS (selective laser sintering), DMLS (direct metal laser sintering), DLP (digital light process), EBM (electron beam melting). Typically these applications involve lowvolumes and complex geometries. Often, components for aerospace and medical applications are ideal candidates for production 3D printing. This paper proposes a new approach to the 3d printing process by using a robotic arm to ensure more than 3 degrees of freedom and deposition paths with spatial orientation. One propose two types of working: nonplanar with the tip normal to the working plane and nonplanar with the tip normal to the trajectory.

This paper gives a complete insight on the systematic procedure required to be followed for design of a three axis robotic system and its implementation as a 3D printer. The mechanical structure of the system is designed based on dimensional and load carrying requirements. The system is equipped with a suitable material extrusion system along with a control system that allows its use as a 3D printer based on the principle of fused deposition modelling.

The process of manufacturing parts with additive technologies has seen tremendous growth in recent years, and the emergence of more 3D open source printers has led to complex and personalized shapes at a lower price. For these reasons, 3D printers that form parts by extruding a filament of molten plastic are becoming standard equipment in many laboratories and workshops. In this context, the paper aims to present some theoretical aspects about the implementation and testing of a low cost 3D printer using open source technologies, the description of its main components and the stages to be taken from the 3D modelling of an object to the proper printing.

The pinnacle of 3D printing is its effect on the field of rapid prototyping. The major advantage comes from the fact that designers can quickly materialize a part or object, which then could be tested in practice, and can be effortlessly modified if needed. This obviously cuts the development expenses and time by a significant percent. Moreover, it’s possible to create complex and precise shapes with the technology, which would take more time and would be resource intensive if done by older methods, for example manual or automatic machining.

This research developed a fully-integrated robotic printing system, using new methods of additive manufacture (AM) that enables users to explore spatially printed structures with increased freedom of geometric complexity. Current AM technologies, such as Fusion Deposition Modelling (FDM), can rapidly translate design ideations into solid forms by precisely depositing consecutive layers of material in coordination with the movements of a robotic platform. Using this method, solid objects are digitally deconstructed into linear toolpaths and physically reconstituted with thermoplastic extrusion equipment; the toolpath becomes the form.

This paper discusses the development of an informed Design-to-Robotic-Production (D2RP) system for additive manufacturing to achieve performative porosity in architecture at various scales. An extended series of experiments on materiality, fabrication and robotics were designed and carried out resulting in the production of a one-to-one scale prototype. In this context, design materiality has been approached from both digital and physical perspectives. At digital materiality level, a customized computational design framework is implemented for form finding of compression only structures combined with a material distribution optimization method. Moreover, the chained connection between parametric design model and robotic production setup has led to a systematic study of certain aspects of physicality that cannot be fully simulated in the digital medium, which then establish a feedback loop for underrating material behaviors and properties. As a result, the D2RP system proposes an alternative method of robotic material deposition to create an informed material architecture.

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 tra...

This paper discusses the way of enriching design methods that embrace a broader spectrum of multiple disciplines in the milieu of digital fabrication. In the first part of this paper, the potential of robotic fabrication and different strategies of design and fabrication are generally discussed; And in the second part a typical case study of robotic fabrication is represented in detail. The Robotic 6-Axis 3D Printing project (Also known as Robotic Extrusion), from Shanghai Digital future 2014 summer workshop, indicates the integration of design concept, parametric tooling, bio-science, materiality and robotic technology.

Increasing industrial demands from the high-value manufacturing industries of quality, productivity, efficiency and security to enable the development of the next generation nuclear power plants has driven the requirement for novel automated and robotic systems. This paper describes the motivation, design and implementation phases of SERFOW (Smart Enabling Robotics driving Free Form Welding), which is an automated welding cell prototype that links the industrial requirements of nuclear manufacturing. Key innovations are found in the integration of a 3D vision system with a robotic manipulator to perform automatic free-form fusion welding for multiple layer material build-up required to expand Additive Manufacturing without human intervention.
