As the idea of crewed outposts on the Moon gains momentum, In-Situ Resource Utilization (ISRU) technologies tend to become imperative to fulfill astronauts' needs. This article explores a way to use the lunar regolith as a source material for the additive manufacturing of complex objects, based on the selective laser melting (SLM) technique. A lunar regolith analog, Basalt of Pic d'Ysson (BPY), is used as a starting point for this study, to investigate the now demonstrated impact of amorphous analog content in the powder bed, substrate type, and post-SLM annealing treatments on the mechanical properties of 3D-printed objects. Improvements to the manufacturing and sample extraction stages are proposed to systematically reproduce the high compressive strength values obtained, thus contributing to the robustness and reliability of the process.

Natural stones are materials with distinct properties that are becoming increasingly popular because of their accessibility, performance, and decorative qualities. In the construction industry, igneous, sedimentary, and metamorphic rock types are frequently used, particularly in landscaping, sculpture, and ceramic production. These wastes are categorized in various forms, such as dust or fines, aggregates, larger pieces of stone, damaged blocks or slabs, and stone slurry. Waste has a significant impact on soil, water, air, and biological resources if problems that arise during and after operations are not properly addressed. In this study, the operating wastes produced during the production of & Ccedil;an Stone, which is defined in the literature as rhyolitic tuff, and has mineral deposits in & Ccedil;an, Turkey, were used as components in recipes created with ceramic triaxial blend systems. The main objective is to eliminate the environmental issues brought on by the accumulation of this waste while also enabling the use of a by-product that has a wide range of applications in various industrial sectors. The chemical compositions of the waste which are added up to 60% into the glaze recipes and raw materials used in recipes were determined by XRF analysis. Among the glaze recipes produced, 6glaze compositions were selected for characterization tests. XRD, SEM, hot stage microscope and spectrophotometer devices were used to characterize the produced glaze samples. Wastes were obtained from & Scedil;ahin Mining Company (& Ccedil;an-Turkey) and included in the formulations of ceramic glazes. Transparent glazes in color tones ranging from light brown to dark brown were obtained in the samples fired at 1200 degrees C.
