WASPer_3DP

Grasshopper plugin · v1.0.5.8 · updated 8/23/2026

WASPer_3DP is a Rhino 8 / Grasshopper plugin for Design for Additive Manufacturing (DfAM). It supports computational design, digital fabrication, and early-stage performance feedback for 3D-printed building components, with a particular focus on large-scale Liquid Deposition Modeling (LDM), clay-based printing, and WASP40100-style workflows. The plugin connects geometry processing, implicit fields, infill generation, slicing, print-path preparation, G-code generation, material/layer data, visualization, and selected research-oriented analysis tools inside one parametric environment. It also supports robotic fabrication workflows: generated `wsp_path` toolpaths contain fabrication data such as planes/targets, layer heights, roles, process values, and metadata that can be used in combination with plugins such as Robots or KUKA|prc. WASPer_3DP also includes a dedicated 5.1_Robot Gcode category with components compatible with the open-source Robots plugin. A central concept in recent versions is the WASPer path (`wsp_path`): a structured fabrication-path container that keeps curves, layers, point-level process values, roles, motion information, and metadata together as one reusable object. This makes it easier to move printing paths through optimization, simulation, G-code, robotic fabrication, visualization, Study Manager workflows, and XR/AR process-viewer workflows without losing the relationship between geometry, process parameters, and fabrication intent. WASPer_3DP is intended for researchers, architects, engineers, fabricators, and makers exploring additive manufacturing for architecture and construction. It is an independent research project developed at Politecnico di Torino and currently enhanced in collaboration with ACTech Hub at the University of Minho. Main capabilities include: - Planar, non-planar, and surface-aware slicing workflows for 3D-printing paths, supporting both 3-axis and selected multi-axis fabrication workflows - 2D and 3D infill generation, including S-patterns, spiral paths, conformal paths, TPMS, polyhedral/cellular systems, brick-like cavities, and custom SDF-based infills - Signed-distance-field tools for implicit geometry, field booleans, offsets, shells, contouring, meshing, field transformation, Isopod/WASPer field exchange, and field-based path operations - Mesh, image, bitmap, and painting tools for generating color fields, scalar fields, local mesh deformation, and texture-driven geometry workflows - Printing-path preparation and optimization, including path construction from curves, path roles, path transformation, flow assignment, point reduction, velocity utilities, fuzzy-skin/fuzzy-pocket tools, proximity-based flow estimation, and path visualization - Marlin G-code generation, parsing, saving, and process simulation for LDM/FDM workflows, currently focused on 3-axis printer workflows - A 5.1_Robot Gcode category with components compatible with the open-source Robots plugin, including Robots target generation from `wsp_path`, target utilities, tool/base helpers, KRL merging, and KUKA post-processing support for robotic fabrication workflows. These robotic fabrication components are functional but still require further testing across different robot setups, tools, and fabrication scenarios. - Facade and panelization tools for UV-based panels, joints, weighted tile layouts, and SDF-informed facade systems - Material and layer utilities for opaque/gas materials, equivalent air conductivity, water-content calculations, 3D-printing material properties, and reusable material/layer records - Morphological and fabrication-oriented characterization tools, including porosity, tortuosity, surface area, printability proxies, shrinkage, pore-flow relation metrics, fresh-deformation risk proxies, and beam-deflection proxy checks - Building-physics research tools, including analytical steady/dynamic thermal calculations, numerical conduction solvers, weather/solar series generators, thermal-field visualization, U-value/equivalent-conductivity utilities, and adaptive comfort calculations. These methods are still under experimental validation at Politecnico di Torino and should be used as research and early-stage comparison tools, not as certified engineering solvers. - Experimental moisture and structural proxy components. These methods are still under experimental validation at Politecnico di Torino and should be used as research and early-stage comparison tools, not as certified engineering solvers. - Native data-visualization tools, including scatter plots, bar charts, box plots, histograms, heatmaps, Pareto fronts, 3D graphs, and parallel coordinates inside Rhino/Grasshopper - CSV/Excel/JSON utilities, Grasshopper document inspection helpers, viewport/image export, and workflow automation utilities - Study Manager workflows for comparing design alternatives, capturing iterations, linking Grasshopper sliders, exporting study data, generating reports, and reviewing design/performance KPIs from a dedicated manager interface - Web-based XR/AR Process Viewer tools for packaging and live-previewing fabrication jobs, including path/mesh playback, contextual printer or scene geometry, mobile access through QR links, and browser/AR inspection of 3D-printing processes The XR/AR Process Viewer is currently intended as an experimental visualization and communication tool, not as a metrology, collision-safety, or machine-control system. AR scale, alignment, browser performance, device compatibility, and live synchronization depend on the receiving device and local network conditions. Sharing is currently local-network / localhost based and does not include an internet-hosted public cloud sharing service. WASPer_3DP is still under active development. Some components may contain bugs, edge cases, changing interfaces, or methods that require further validation. Feedback, bug reports, suggestions, and examples of use are always welcome.
