ABSTRACT
QMesh (QuasiMesh) presents the concept of multifunctional surfaces created via fused deposition modeling (FDM) technology. Depending on the material used, layers of 3D-printed objects can exhibit a range of surface features, from glossy to matte and smooth to rough. Although a minimal set of parameters can be adjusted in the software to incorporate such features, they primarily provide an aesthetic look, lacking versatile functionalities and use cases.
This project explores how adjusting single parameter such as the extrusion multiplier enables the development of multifunctional, mesh-like surfaces. These surfaces are designed not only to have a pleasing appearance but also to provide tactile feedback, incorporate soundproofing properties, and offer mechanical functionalities for use in hook-and-loop systems, among other potential applications.
INTRODUCTION
In FDM technology, the external perimeter of a 3D-printed object can be manipulated to produce a wide range of textures and finishes. Adjusting the 3D printer extruder temperatures during printing can make surfaces glossy or matte. Additionally, features such as the “Fuzzy skin” option available in most slicing software allow for the creation of rough, fiber-like textures on the sides of models. This feature can enhance grip when applied to tool handles, demonstrating that the potential of these surfaces extends beyond mere aesthetics. By fine-tuning specific parameters, the functional properties of such surfaces can be further extended, enhancing their practical applications.
The extrusion multiplier is the primary parameter on which the QMesh concept relies. Adjusting this single parameter can transform the surface characteristics of 3D printed objects, leading to the creation of surfaces that are not only visually appealing but also functionally beneficial. For instance, our findings indicate that surfaces can be engineered to behave like porous, thick, foam-like materials, providing soundproofing capabilities for the final product. Additionally, these surfaces can be ironed onto fabrics, making them suitable for use with hook-and-loop badges that require sewing.
The design of QMesh works with standard shapes such as boxes or spheres found in slicing software (slicers) and does not require any computer-aided design (CAD) software. The mesh itself is made from rectilinear pattern infill without any external or internal parameters. A single bottom surface is used as a raft for adhesion, but this is optional. The extrusion multiplier defines the softness and brittleness of the mesh. The infill density parameter defines how dense or sparse it will be. Both parameters can be adjusted to create a mesh that is either thick and porous or sparse and soft.
APPLICATIONS
Acoustic Reflection and Absorption
A 3D-printed acoustic panel with varying surface geometries and material densities can exhibit different acoustic properties, including sound reflection and absorption. While primarily presented as a conceptual study, variations in thermoplastic materials and design configurations may result in a range of acoustic performance levels, from less effective to more effective.
Iron-On Material
A thin raft can be formed around a mesh surface and then ironed onto fabric, providing an option for carrying hook-and-loop badges or creating a storage wall for such items. While the surface is porous, its durability is limited, and it may eventually tear if badges or other items are attached and removed frequently.
