-The article presents algorithms for the control of a robotic complex for building products using 3D printing, including a module for the main movements and a module for precise movements based on a robot with a cable drive. The description of software modules for the implementation of algorithms and the technology of printing with the use of a printing module and a control unit for the supply of printing material are described. The basic principles of the operation of the program modules and the program interface are considered. There is a detailed selection of 3D print settings in the developed software module such as layer height, type of filling of the model with printing material, printing of supports, etc. Recommendations are given on the optimal choice of these settings to achieve the required quality of the obtained product models. The results of modeling are presented.

“…8 However, traditional SLA machines are, like most AM equipment, designed to build parts on planar reference surfaces and do not easily permit construction on nonplanar substrates. Moreover, the working volume of AM systems, which typically use orthogonal gantry style motion systems, 14 is limited, even though the forces involved in deposition are significantly lower than the forces in conventional machining operations. In the case of SLA, 17 the machine design is also restricted by the requirement to dispense and/or recoat the resin with each layer, 18 and steeply overhanging surfaces of parts must be supported by scaffolds that are often painstaking to remove and compromise the surface quality of the part.…”

“…[6][7][8][9] For example, Align Technologies uses SLA for mass-customized production of millions of dental replicas that are used to mold unique orthodontic aligners, 10 and SLA is used extensively in the film and architecture industries for prototyping of both small-scale and large-scale models and props. 2,[11][12][13][14][15] Recent advances in SLA technology include desktop machines that incorporate low-cost lasers and/or digital light projectors (Formlabs Form 2, Nobel 1.0), significantly faster SLA printing achieved by local modulation of oxygen-induced inhibition, 16 and SLA printing of siloxane-based resins that can be converted into ceramics on subsequent heat treatment. 8 However, traditional SLA machines are, like most AM equipment, designed to build parts on planar reference surfaces and do not easily permit construction on nonplanar substrates.…”

Additive manufacturing by layerwise photopolymerization, commonly called stereolithography (SLA), is attractive due to its high resolution and diversity of materials chemistry. However, traditional SLA methods are restricted to planar substrates and planar layers that are perpendicular to a single-axis build direction. Here, we present a robotic system that is capable of maskless layerwise photopolymerization on curved surfaces, enabling production of large-area conformal patterns and the construction of conformal freeform objects. The system comprises an industrial six-axis robot and a custom-built maskless projector end effector. Use of the system involves creating a mesh representation of the freeform substrate, generation of a triangulated toolpath with curved layers that represents the target object to be printed, precision mounting of the substrate in the robot workspace, and robotic photopatterning of the target object by coordinated motion of the robot and substrate. We demonstrate printing of conformal photopatterns on spheres of various sizes, and construction of miniature three-dimensional objects on spheres without requiring support features. Improvement of the motion accuracy and development of freeform toolpaths would enable construction of polymer objects that surpass the size and support structure constraints imparted by traditional SLA systems.

“…Barnett and Gosselin (Barnett and Gosselin 2015) have been first to demonstrate 3D printing with a CDPR. The provided design is so-called suspended, meaning that all cables are drawn upwards from the platform, leaving the work area collision free.…”

Gantry robots and anthropomorphic arms of various sizes have already been studied and, while they are in use in some parts of the world for automated construction, a new kind of wide workspace machinery, cable-driven parallel robots (CDPR), has emerged. These robots are capable of automated movement in a very wide workspace, using cables reeled in and out by winches as actuation members, the other elements being easily stacked for easy relocation and reconfiguration, which is critical for on-site construction. The motivation of this paper is to showcase the potential of a CDPR operating solely on motor position sensors and showing limited collisions from the cables for large-scale applications in the building industry relevant for additive manufacturing, without risk of collisions between the cables and the building. The combination of the Cogiro CDPR (Tecnalia, LIRMM-CNRS 2010) with the extruder and material of the Pylos project (IAAC 2013) opens the opportunity to a 3D printing machine with a workspace of 13.6 9 9.4 9 3.3 m. The design patterns for printing on such a large scale are disclosed, as well as the modifications that were necessary for both the Cogiro robot and Pylos extruder and material. Two prints, with different patterns, have been achieved with the Pylos extruder mounted on Cogiro: the first spanning 3.5 m in length, the second, reaching a height of 0.86 m. Based on this initial experiment, plans for building larger parts and buildings are discussed, as well as other possible applications for CDPRs in construction, such as the manipulation of assembly processes (windows, lintels, beams, floor elements, curtain wall modules, etc.) or brick laying.
