“…The differences between various design methods and guidelines are explained below using selected examples. There are many general AM design methods or guidelines which have design rules as a topic and already cover the challenges described above well (Adam and Zimmer, 2015;DIN EN ISO/ASTM 52910, 2020;Lachmayer et al, 2022;Materialise, 2023;Junk and Bär, 2023). Lachmayer et al (2022) have developed a design catalogue for AM as a supporting tool for the design of standard components such as hollow cylinders.…”

In recent years, interest in additive manufacturing has increased. To overcome challenges such as the correct use of the technology, guidelines are needed to help the user in the fabrication process. However, such guidance is not currently available for all applications. This paper dives into design methods in AM and their transfer to an application example in the field of medical technology. The aim of this paper is to analyse the transferability of a design method for vessel models to small vessel models. To this end, an initial printing study is carried out on simplified hollow structures.

“…In order to additively manufacture a component, the component passes through the three process steps pre-, in-, and post-process. [3,26,28,48] The starting point for AM is always the associated CAD model. If no CAD model is available, it can be generated by CAD modeling or reconstructed by 3D Digitalization.…”

“…If no CAD model is available, it can be generated by CAD modeling or reconstructed by 3D Digitalization. [3,28] The subsequent pre-process includes data preparation, placement of the part in the build space, generation of support structures (if needed), machine setup, slicing, and preparation of the AM system. Data preparation is necessary because the CAD model must first be converted into an interface format to be used in AM systems.…”

“…After completion, the component is removed from the build space and cleaned or unpacked. [3,28,48] All working steps that are executed after the component are removed from the system are assigned to the post-process. For example, the removal of support structures or powder residues takes place.…”

“…For example, the removal of support structures or powder residues takes place. [28,48] In addition to the pre-, in-, and post-process, a post-treatment can be applied "in order to achieve selected properties, to improve them or to introduce further features" [48]. Depending on the aimed results, different processes are used.…”

Alignment of design rules for additive manufacturing and remanufacturing

et al. 2022

Remanufacturing is one key element of a circular economy by closing the loop on the product level and thus maintaining or restoring the product design and the associated product properties. The remanufacturing process chain involves disassembly of used products, cleaning of parts, inspection and sorting of parts, reconditioning or replenishment by new parts, and product reassembly into as-new products. If new parts are required, additive manufacturing is a promising alternative to conventional manufacturing or the purchase of spare parts. Additive manufacturing is characterized by the layered or element-based construction of parts and does not require product-specific tools, enabling a cost-efficient production of individual pieces or small series. The use of specific design rules in product and process development to meet the requirements of the intended process enables and simplifies additive manufacturing or remanufacturing. Despite the design rules for additive manufacturing and remanufacturing, there are no design rules for implementing additive manufacturing technology in the remanufacturing process. In this paper, existing design rules on Design for Additive Manufacturing and Design for Remanufacturing will first be identified and compared, and possible synergies and conflicts of objectives will be analyzed. Based on this, a guideline for a Design for Additive Remanufacturing is developed to facilitate and promote the implementation of additive manufacturing in remanufacturing. The developed design rules enable the evaluation of a part aimed to be produced by additive manufacturing within the remanufacturing process and give advice on how to optimize the design of the part. This paper aims to derive general design rules for a “Design for Additive Remanufacturing” that specifically address the additive remanufacturing process.
