Companies are trying to develop the manufacturing capabilities to meet the tighter specifications and quality requirements of the customers, but at the same time struggling to keep the offered prices within accepted levels. This study focuses on exploring and evaluating experimentally the manufacturing process capability of the 3D printers to produce 3D printed parts of different geometries and internal designs to minimize the costs lost. This has been achieved by estimating the actual specifications limit of the studied 3D printers. Moreover, the study starts with exploring the manufacturing process capability and the specifications limit of the available 3D printers in UAEU as well as commercial and industrial 3D printers available in the domestic market. Besides, to come up with guidelines and conclusions to help in understating the specifications of the 3D printers that aimed to be used. Different 3D printers are built to test the process capability of assembled 3D painters to support the objective of the study. Keywords Dimension tolerance, precision, process capabilities 1. Introduction Recently, 3D printing has become a robust field that is developing significantly to revolute the manufacturing processes. Many disciplines like mechanical, electrical, biomedical and aerospace industries utilize 3D printing to improve the design manufacturing and to minimize the lead time, as well as reducing the tooling cost for new components produced. 3D printing differs from conventional machining such as turning, milling, and drilling, which helped people many decades ago to build products. However, in the past few years, they are no longer used as much as before because they have some limitations and constraints, such as the expensive cost of the production processes. In this regard, the concept of 3D printing has presented. It is also known as additive manufacturing, which is a part of rapid prototyping in which 3-dimensional products can be formed from a digital file. Additive manufacturing meant to be the deposition of a specific material layer by layer until the desired object is created as per the given design. Those layers that combined one on top of the other is nothing more than a horizontal cross-section of the product itself. The quality of the object printed using 3D printer relies on the composition of the material added, the manufacturing process, the speed in which the printer operates, the type of 3D printer used, and eventually, the volume of the part printed using that printer. In general, 3D printing technology has a significant contribution to the world in many directions because of the remarkable advantages to the industrial sector and has a substantial impact on the other 2618
