Abstract
The objective of this publication is to present a quality control methodology for additive manufacturing products made of polymer materials, where the methodology varies depending on the intended use. The models presented in this paper are divided into those that are manufactured for the purpose of visual presentation and those that directly serve the needs of the manufacturing process. The authors also a propose a comprehensive control system for the additive manufacturing process to meet the needs of Industry 4.0. Depending on the intended use of the models, the quality control process is divided into three stages: data control, manufacturing control, and post-processing control. Research models were made from the following materials: RGD 720 photopolymer resin (PolyJet method), ABS M30 thermoplastic (FDM method), E-Partial photopolymer resin (DLP method), PLA thermoplastic (FFF method), and ABS thermoplastic (MEM method). The applied measuring tools had an accuracy of at least an order of magnitude higher than that of the manufacturing technologies used. The results show that the PolyJet method is the most accurate, and the MEM method is the least accurate. The findings also confirm that the selection of materials, 3D printing methods, and measurement methods should always account not only for the specificity and purpose of the model but also for economic aspects, as not all products require high accuracy and durability.

Summary
With the increasing application of additive manufacturing technologies in the fabrication of end products, it became necessary to establish standards for 3D printing quality and the organization of processes within the entire delivery chain [37]. PN/EN ISO 17296-3:2016-10 Additive Manufacturing—General Principles—Part 3: principal characteristics and appropriate research methods This standard is primarily dedicated to machine producers and users, feedstock and part suppliers, and recipients and customers. PN/EN ISO 17296-4:2016-10 Additive Manufacturing—General Principles—Part 4: Overview of data processing This standard contains issues related to data exchange. It describes terms and definitions applied to the exchange of information about the geometry of parts (products) manufactured with additive manufacturing. ISO/ASTM 52911-1:2019 Additive manufacturing—Design—Part 1: Laser-based powder bed fusion of metals This standard defines the characteristics of the laser-based powder bed fusion of metals (PBF-LB/M) and contains detailed design recommendations. This document defines the characteristics of the laser-based powder bed fusion of polymers (LB-PBF/P) and contains detailed design recommendations. The Committee for Standardization continually works on further standards applicable to additive manufacturing
