Elevating 3D Scanning Quality with AESUB Sprays
3D scanning has become an indispensable tool across various industries, from reverse engineering and quality control to design and medical applications. However, achieving high-quality scans isn’t always straightforward. Certain object characteristics – such as transparency, reflectivity, or very dark surfaces – can pose significant challenges for optical 3D scanners. These surfaces often absorb or refract light in ways that prevent the scanner from accurately capturing the object’s geometry, leading to incomplete data, noise, and ultimately, a lower quality 3D model. This is where specialized solutions become crucial.
Addressing these common hurdles, the German company AESUB has developed a revolutionary line of scanning sprays designed to drastically improve the reliability and accuracy of 3D scan data. Their innovative sprays create an ultra-thin, homogeneous matte white coating on the object’s surface. This uniform layer ensures that the scanner’s light beams are consistently reflected, allowing for comprehensive and precise data capture. The result is a clean, highly accurate scan, free from the distortions and data gaps typically associated with challenging surfaces.
One of the most significant advantages of AESUB sprays is their convenience and efficiency. Many of their products are self-evaporating, meaning the fine white layer disappears completely after a few hours, leaving no residue on the scanned object. This eliminates the need for post-cleaning, saving valuable time and labor, and making the scanning process incredibly streamlined. This feature is particularly beneficial for delicate or valuable items where residue removal could be problematic. AESUB offers various formulations, including permanent options for situations where a lasting coating is preferred. By choosing the right AESUB spray, users can optimize their workflow, achieve superior scan results, and unlock the full potential of their 3D scanning equipment for a wide array of applications, from intricate industrial components to large-scale artistic pieces.

Anatomy of 3D Printed Parts: Understanding Walls and Supports
Continuing our insightful miniseries on the fundamental anatomy of 3D printed parts, this second installment delves into two critical structural elements: walls and supports. These components play pivotal roles in determining the structural integrity, aesthetic quality, and overall success of a 3D print. Understanding their function and how to optimize them is essential for anyone looking to achieve professional-grade results from their additive manufacturing projects, regardless of the printing technology used.
Walls, often referred to as perimeters or shells, form the outer and inner boundaries of a 3D printed object. They are crucial for creating the part’s external surface finish, providing structural rigidity, and ensuring features like watertightness or airtightness. The number of walls, their thickness, and their infill density directly impact the strength, weight, and material consumption of a print. For instance, a part requiring high strength or abrasion resistance might benefit from a greater number of perimeters, while a purely aesthetic model could use fewer. Walls are particularly important for surfaces that are not directly parallel to the build platform, as they define the contours and details of the object. Proper wall settings in slicing software are paramount for achieving a smooth surface finish, accurate dimensions, and preventing issues like ghosting or gaps.
On the other hand, Supports are sacrificial structures specifically designed to brace and hold up portions of a 3D print that would otherwise print in mid-air – commonly known as overhangs or bridges. Without supports, these unsupported sections would deform, sag, or fail completely during the printing process, leading to print failures or compromised part quality. Supports come in various forms, including tree-like structures, lattice patterns, or solid blocks, and can be printed from the same material as the part or from a different, often soluble, material. The choice of support type and density depends on the geometry of the overhangs, the material used, and the desired surface finish. While essential for complex geometries, supports must be carefully considered during the design phase (Design for Additive Manufacturing – DfAM) to ensure they can be easily removed without damaging the part and to minimize post-processing efforts. Effective support strategies balance structural necessity with ease of removal and minimal impact on the final part’s appearance.
