Abstract

Polymer toybricks are available in different shapes and sizes, and their price varies significantly. The aim of this paper is to test whether high price of some brands of toybricks corresponds to their quality, in terms of dimension accuracy. For this purpose, two kinds of toybricks were tested: one made by the renowned LEGO® company, the other model made by anonymous Chinese manufacturer. In addition to visual differences, such as colour stability and finishing quality, the difference is in quality and accuracy of shapes and dimensions that can affect the characteristics of the bricks, such as: quality and stable connection with other bricks in the assembly, lifetime etc. The main characteristic tested here is the dimension tolerance of specific dimensions of toybricks.
