Design Process for Additive Manufacturing, 2nd Edition

Dear Colleagues,

This is the second edition of a previous successful Special Issue, “Design Process for Additive Manufacturing” (https://www.mdpi.com/journal/designs/special_issues/8A27O796W2).

Additive manufacturing processes are rapidly growing technologies that can produce highly complex models. Depending on the manufacturing method, the size of the part, and its complexity, it can take several hours or even days to create finished models using additive techniques. Currently, numerous additive manufacturing methods are available. AM models are widely utilized in the automotive, aerospace, and medical industries. Since functional models are often produced using additive technologies, they must meet requirements related to strength assessment, dimensional–geometric tolerancing, and surface roughness. This necessitates the development of a 3D-CAD model in the design process that aligns with the designer's goals. This process can be challenging when creating models for 3D printing. When creating a 3D-CAD model for 3D printing, traditional modeling using computer-aided design systems is commonly used. Challenges arise when technological or material documentation is not available for a product. This is especially common when designing models of anatomical structures, museum artifacts, or other complex geometric models where solid or surface design is usually impossible. The reverse engineering (RE) process can solve this problem thanks to advancements in coordinate-measuring systems, data processing software, and modern manufacturing techniques. This design process is also frequently used for developing 3D-CAD models for 3D printing, but it can lead to geometric mapping errors during the design stage.

Given the current state of the literature, standards related to the traditional design of 3D-CAD models and the RE process for AM have yet to be developed. The lack of development of design assumptions by the AM technique in the design and manufacturing stage greatly restricts the commercialization of finished products for the automotive, aerospace, or medical industries. Therefore, this research problem warrants careful attention.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Designs is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
