“…Additive manufacturing (AM) allows CMs to be produced at a microscopic scale, which is impossible for rigid-body mechanisms due to their complexity. This also increases compliant mechanisms' portability over traditional mechanisms due to generally reduced size and lightweighting properties (Danun et al, 2020;Kiener et al, 2021).…”

Additive manufacturing methods present prospects for designed mechanical deformation via the integration of controlled anisotropic lattice structure forms. Their assimilation into a Design for Additive Manufacturing (DfAM) process would create a novel framework for the design of compliant mechanisms (CM). The method uses lattice structures to replace rigid multi-part mechanisms, with integrated and controlled flexibility into a single, compact, and precise component. In recent years, a lot of research has gone into making algorithms that enable users to generate CMs for their designs. But by relying on algorithms to design solutions, are they neglecting to fully understand how these mechanisms work. This work undertakes the design and development of a novel DfAM Framework, that utilises controlled lattice structure deformations to create a standardised method of CM design. The authors have developed a method for this, whilst allowing users to tailor CMs to their design, by using a wide selection of pretested structures. Indicating suitable structures for their design using an integrated novel taxonomy. The framework is tested and developed using a series of case studies.

“…To do so, one can employ thinner struts at the hinge site or generate cut-out structures that will add flexibility to the part . Compliant mechanisms are often generated through latticing, which generates regions of reduced density and increased pliability . In the case of the stretch D-MAP design, latticing can be added onto the prongs to facilitate bending and stretching of the skin, as the needle is inserted.…”

The use of elastomeric polymer resin can also facilitate generation of compliant mechanisms as the material itself will have inherent deformation.…”

The intradermal (ID) space has been actively explored as a means for drug delivery and diagnostics that is minimally invasive. Microneedles or microneedle patches or microarray patches (MAPs) are comprised of a series of micrometer-sized projections that can painlessly puncture the skin and access the epidermal/dermal layer. MAPs have failed to reach their full potential because many of these platforms rely on dated lithographic manufacturing processes or molding processes that are not easily scalable and hinder innovative designs of MAP geometries that can be achieved. The DeSimone Laboratory has recently developed a high-resolution continuous liquid interface production (CLIP) 3D printing technology. This 3D printer uses light and oxygen to enable a continuous, noncontact polymerization dead zone at the build surface, allowing for rapid production of MAPs with precise and tunable geometries. Using this tool, we are now able to produce new classes of lattice MAPs (L-MAPs) and dynamic MAPs (D-MAPs) that can deliver both solid state and liquid cargos and are also capable of sampling interstitial fluid. Herein, we will explore how additive manufacturing can revolutionize MAP development and open new doors for minimally invasive drug delivery and diagnostic platforms.

“…Central to its effectiveness is its ability to produce custom components, especially for specialized applications like compliant mechanisms. [ 1 ] These mechanisms, inherently flexible devices that transfer motion, have gained increasing importance in industries for their adaptability. One crucial determinant of the performance of these 3D printed compliant mechanisms is the material selection.…”

The paper presents a study on the dimensional and weight characterization of 3D printed polyethylene terephthalate specimens designed specifically for compliant mechanisms. Compliant mechanisms find applications in various industries, including medical, consumer goods, education, and research and development. Ensuring these mechanisms meet the required functional needs is crucial, particularly when customizing medical devices. The research focuses on material selection, a critical aspect for 3D printed compliant mechanisms. To investigate the influence of the material deposition angle on the quality and precision of 3D printing, the study considers traction and bending specimens. For each specimen type, three sets of five specimens are manufactured, incorporating different deposition angles: 0°, ±45°, and 90°. In total, 30 specimens are produced, labeled, weighted, and measured. The results reveal that specimens printed at a deposition angle of 45° exhibit the smallest dimensional and mass deviations, indicating higher precision and accuracy. Those printed at 0° follow closely in terms of deviation, while specimens printed at 90° display larger deviations.
