Abstract
The importance of 3D printing is primarily that it enables customized production and, through Industry 4.0 technology, enables decentralized production. The article deals with the issue of 3D modelling and 3D printing of plastic respirators in the laboratory conditions of the authors’ workplace. In the above case study, the process of creating 3D models of individual parts of a plastic respirator and the production of a given model using a 3D printer is processed. The article also outlines the trends in 3D printing in connection with Blockchain and their importance on the Supply Chain.
Highlights
Each of these sections has been modified in Voxelizer 2.0.0. This program is recommended for the given printer and is completely adapted for editing models that will be printed with the help of the Zmorph 3D printer, see Figure 9
3D printers were used by larger corporations to produce prototypes, which were used to modify the final version of their product to meet requirements. 3D technology is not universally suitable for various types of products
The advantage of using plastics in 3D printing is the possibility of re-recycling, which is, limited by the number of recycles, as plastics become contaminated in some way and when they melt, their properties are degraded
Summary
In connection with 3D printing, it is possible to highlight the advantages of Blockchain, which can be used effectively within the Supply Chain, especially in guaranteeing relevant information about material, production, quality, chain entities, etc. [11,12,13,14]:. The importance of Blockchain is generally in the protection and sharing of data related primarily to print licenses, production process data, material origin information, tests and simulations, payment records, and parts certification [14]. In a study by Klöckner, M., [14] Table 1 contains material that points to the importance of Blockchain in connection with 3D printing. The study defines the potential for business model innovation for local manufacturing, shared factories, and secure design marketplaces well-crafted findings of authors to increase the innovative capacity of business models. Offer an improved value delivery (local, on-demand printing) Offer less expensive products (cut logistics costs). Secure transfer of design files Production outsourcing to local manufacturers, service providers, or customers Full transparency about a printed part’s life cycle.
