Sažetak
Additive manufacturing is the modern technology that uses a computer-aided design product data to create its real physical replica. In the industry already exist a vast number of different additive manufacturing processes that use various types of materials, from polymers to metals, to create new products and prototypes. Fused deposition modeling (FDM) is one of the well-known additive manufacturing processes. It is able to create products that can be treated and used further in the manufacturing process. These products have very acceptable mechanical properties. These properties mostly depend and vary according to process parameters values and can be optimized by setting process parameters on appropriate levels. In this paper, a fuzzy logic modeling approach was used to analyze the influence of variable process parameters: top and bottom surface layers number, fill spacing, and layer resolution on ultimate tensile strength and manufacturing cost. Experiments were conducted on the PLA (Polylactic Acid) biodegradable material but it can be also tested on some other materials such as ABS, PC, PSU, PEEK and etc. Developed models were used to describe the process and determine process parameters values that lead to maximal tensile strength and minimal cost. Findings in this paper can be significant for users involved in this type of process to obtain a higher quality product and desirable savings.
