This work presents a framework for integrating processes in hybrid manufacturing that 
utilizes the strengths of each process. This work focuses on hybrid methods such as ''fused 
deposition modelling'' and ''CNC machining''. The hybrid technique is built on a system 
that creates a framework for interrelationships, allowing effect and value to be understood 
and appraised. The analytic hierarchy process (AHP) organizes decision making, using 
what has been learned about the previous procedures to successfully component 
complexity management for effective design and manufacturing the most valuable 
element. The prime focus of this study is to improve a method for selecting process 
parameters, evaluating the mechanical and physical properties of specimens creating using 
the fused deposition modelling technique. Before utilizing FDM to create a product, a 
number of parameters must be established. The component orientation, infill pattern, fill 
density, layer thickness, printing speed, and shell thickness are some of these variables. 
There are certain outputs from the final component that can be noticed, examinations and 
measures. Some of these replies include the final product's dimensions and mechanical 
characteristics, such as its tensile strength, impact strength, and compression strength. In 
this study, the link between the process variables of a 3D printer employing fused 
deposition modelling (FDM) technology and a CNC machine for the output was examined. 
The substance used was PLA plastic, which was widely used in the sector. Knowing the 
connection between the parameters and the outcomes enables the production of the final 
product to satisfy user requirements. Responses were gauged and evaluated for 
dimensional correctness and product robustness. Dimensions of mechanical test specimens' 
gauge areas (tensile strength, impact strength, and compression strength) fabricate in 
comparison with the measurements specified by (ASTM 638-03, ISO 180), and (ASTM 
D695 ) correspondingly also served as a measure of dimension correctness. The analytic  
hierarchy process (AHP) to identify the operation parameters that have an effect on the 
mechanical and physical attributes of the specimens.
