Overview

This diploma thesis dives into the potential of creating vibrant, detailed 3D geovisualisations using Fused Filament Fabrication (FFF) 3D printers and associated tools. The research objectives were set to test the capabilities of multicolour printing equipment, optimise printing parameters for high-quality results, and disseminate knowledge through a comprehensive multicolour 3D printing booklet. Environmental impact, particularly waste material, was also a focal point of the study.

Utilising data from various sources including Copernicus Land Monitoring Service, OpenStreetMap, and ARCDATA PRAHA, several models of varying complexity were meticulously crafted. Data processing was executed using ArcGIS Pro and QGIS, while 3D modelling was performed using CAD software, specifically SketchUp. Additional tools such as 3D Builder and Autodesk Netfabb were instrumental in repairing and refining the models.

Printing configurations and model slicing were executed using PrusaSlicer, Canvas (by Mosaic Manufacturing), and Bambu Studio to generate G-code. The printers and add-ons, including the Prusa i3 MK3S, Palette 3 Pro, Bambu P1S, Bambu Automatic Material System (AMS), and the Prusa XL, brought the models to life. Post-processing steps ensured the quality of the final products.

User feedback played a pivotal role in the research. Through digital surveys and user interactions with the models, key areas for improvement were identified. Notably, an exercise was conducted with users with varying levels of visual impairment, aiming to make the geovisualisations accessible to all. While most of the feedback was earmarked for future endeavours, it provided valuable insights for improvement.

The research culminated in 14 engaging multicolour 3D geovisualisations and an accompanying booklet, documenting the key findings and methodologies. Among the tested equipment, the Prusa XL stood out for its efficiency, albeit with cost considerations. The balance between price and functionality with multi-material add-ons for single extruder printers was explored, and even though there is increased waste and print time this option offers excellent value and is more likely to be embraced by a wider audience.
