“…For this reason, application of measures relates mainly to ensuring of reliable and safe technical condition preventing the origination of hazardous event itself (e.g., prevention of leak by preventive maintenance) -the so-called preventive measures [33][34][35][36][37]. To reduce the consequences, tools, trying to reduce the extent of damage after hazardous event origination (e.g., sprinkling, extinguishing, alarm sirens) -the so-called reactive measures, are applied.…”

Even though the rules for free movement of machinery within the European Union market have existed for more than 30 years, accidents related to their activities have constantly been achieving significant value. When designing the machine, a designer must stem from risk assessment, whereas all stages of its life cycle and ways of its use must be taken into consideration. In industrial operations, there is old machinery, which, although fulfilling its function reliably, the safety level is not in accordance with the developing requirements for their safe operation. The proposed methodology of assessment of the machinery safety condition comes out from the presupposition of the right application of steps of risk assessment and their reduction mainly by means of implementation of both effective and efficient preventive measures. The aim of the research applied in 3 operations, was to verify the method of machinery safety management. The created methodology based on 19 requirements for safety evaluates the level of the actual measures by means of the so-called criterion of current status and total efficiency of measures. Its output is the assessment of the efficiency level of implemented safety of each machine as well as of the whole operation.

“…The solidified fiber was then wound on a spool using a winder. Once produced, the fiber was checked visually and also with a measuring device to examine whether it has the required diameter and whether its quality meets the 3D printing requirements [Stejskal 2019]. The created fiber could be used immediately after having been produced in the 3D printing process of components [Guo 2010].…”

Additive manufacturing, also known as 3D printing, is the process of joining organic, ceramic, polymer, metal and others materials. Most often used as input material are the ABS and PLA plastics. A large number of plastic products is constantly generated by industry, which beckons the idea how to manufacture these products in more environmentally friendly way. This paper deals with the possibility of producing a 3D printing fiber from a granular PLA material Ingeo 2003D with the addition of a mixture of color powder pigment and fiber from the selected PLA material with a glass powder filler. The production was carried out using the FilaFab PRO EX350 device, which is designed for fiber extrusion for 3D printing technology. The aim of the experiment was the creation of new materials in the form of fibers and their mutual comparison in tensile tests with commercially available materials intended for 3D printing.

In recent years, additive production technology has spread to almost all manufacturing areas. In most cases, a fiber is used as an input material in the 3D printing process, the required properties of which are mainly its strength and durability. With the ongoing development of the 3D printing techniques, the need to develop fibers that do not pose a burden to the environment comes to the fore. This paper points out the possibilities of producing fibers intended for additive production. The paper describes the fiber production on FilaFab PRO EX350 device used for producing fibers for the 3D printing technology. The aim of the paper is to describe the production of fibers and to compare commonly available fibers with the experimentally made ones. To run the tests, a clear fiber and a composite fiber with carbon powder filler were produced. The mechanical properties achieved by these experimentally produced fibers were compared in tensile tests with commonly available fibers purchased from sellers of 3D printing materials.
