Laminated object manufacturing vs. Fused deposition modeling : machine comparison

Products made by additive manufacturing are increasingly replacing the products made by classical procedures of polymer processing. The current market requires the products to be of good mechanical properties, low prices, and complicated geometry. With the procedures such as Fused Deposition Modelling and Laminated Object Manufacturing it is possible to produce a product of relatively low price and good mechanical properties. In practice it is impossible to avoid using the products in various atmospheric conditions (e.g. UV radiation and humid environment) either intentionally or unintentionally. The UV light, the Sun being its usual source, , and the average humidity of countries worldwide can vary from 20% to 90%, depending on the weather, day and geographic location. It is therefore necessary to determine how UV light, after a longer exposure, affects the final mechanical properties of the products. A comparison of tensile strength and elasticity module of the test specimens in FDM and LOM procedures has been performed.
