“…However, a modified version of this process known as 'electrochemical-electrodischarge machining' can be applied to polymers. In this process, polymer surface ablates by temperature increase and heat release that accompanies electrical discharges [9]. LST, on the other hand, is a one-step non-contact process.…”

Micro- and nanoscale structures produced on surfaces of metals, polymers, ceramics, and glasses have many important applications in different fields such as engineering, medical, biological, etc. Laser ablation using ultrashort pulses has become the prominent technique for generating different surface structures for various functional applications. Ultrashort laser ablation proved to be ideal for producing structures with dimensions down to the nanometre scale. In comparison to other texturing techniques employed to create micro/nano features such as electrochemical machining, micro-milling, ion-beam etching, hot embossing, lithography, and mechanical texturing, ultrashort laser ablation produces high-quality surfaces at low cost in a one-step non-contact process. Advantageous characteristics of polymers such as high strength-to-weight ratio, non-corrosive nature, and high electrical and thermal resistance, have made polymers the preferred choice compared to other materials (e.g., steel, aluminium, titanium) in several fields of application. As a result, laser ablation of polymers has been of great interest for many researchers. This paper reviews the current state-of-the art research and recent progress in laser ablation of polymers starting from laser-material interaction, polymer properties influenced by laser, laser texturing methods, and achievable surface functionalities such as adhesion, friction, self-cleaning, and hydrophilicity on commonly used polymeric materials. It also highlights the capabilities and drawbacks of various micro-texturing techniques while identifying texture geometries that can be generated with these techniques. In general, the objective of this work is to present a thorough review on laser ablation and laser surface modification of a variety of industrially used polymers. Since direct laser interference patterning is an emerging area, considerable attention is given to this technique with the aim of forming a basis for follow-up research that could pave the way for potential technological ideas and optimization towards obtaining complex high-resolution features for future novel applications.

“…• roztwarzanie elektrochemiczne: obróbka elektrochemiczna ubytkowa (ECM) [10,11]; w obróbce elektrochemicznej materiał jest usuwany najmniejszymi porcjami, atom po atomie; z tego względu przy optymalnie dobranych warunkach obróbki można uzyskać bardzo dobre właściwości powierzchni obrabianego metalu czy stali; z uwagi na brak sił mechanicznych działających na przedmiot obrabiany i narzędzie proces znajduje szerokie zastosowanie w mikro- i nanowytwarzaniu. W metodach formowania -czyli nadawania kształtu bez zmiany masy i objętości -istotną rolę, zwłaszcza w produkcji masowej, odgrywają (obok obróbki plastycznej) procesy odlewania oraz wytwarzania metodą wtrysku (injection moulding) [7,12,13].…”

In 1959 R.P. Feynman has presented the concept and strategy of micro- and nanotechnology development. Their introduction to the practice took place after working out the scanning tunneling microscopy (1981) and atomic force microscopy (1985). In the further development of micro- and nanotechnology the micro and nano electromechanical systems (MEMS, NEMS) have been worked. MEMS and NEMS are widely applied in majority of modern equipment and the production of the equipment increases about 17÷20% per year since 1990s. MEMS and NEMS manufacture usually is a difficult technological problem because of small dimensions and complex outside and inside structures. In such cases the application of additive manufacturing processes can be very promising. In the paper the possibilities of additive manufacturing processes applications, mainly in microtechnologies, is presented.

In the introduction, we present an overview of previous research on this subject in order to help the reader review possible technological solutions regarding the joining of construction materials. The original research presented in this article concerns the results of increasing the shear strength of adhesive joints of plastics using various types of surface preparation (laser texturing). Laser texturing consists in developing the surface by applying various geometric patterns of appropriate shapes and depths, as well as its density on the surface. The above parameters are currently selected in an empirical way as research is still being developed as part of a research project. The textures obtained in this way are subjected to microscopic examination. Then, a layer of glue is applied, and the samples prepared in this way, after drying, are subjected to various destructive tests, e.g., tensile, shear, and bending. In this article, we attempted to test the strength of the bonded joint of polyethylene (PE). The impact of a laser beam with ultrashort picosecond pulses was used in the research. Tools in the form of a TRUMPF TruMicro 5325c device integrated with a SCANLAB GALVO scanning head were used. This enabled ablative material removal without the presence of a heat affected zone (HAZ) in the non-laser part. Ultrashort laser pulses remove material without melting the non-exposed area by the laser beam. On the basis of the tests performed (in this article and previous research works of the authors), it was shown that the method increases the shear strength of the glued joints made in the tested construction materials. This is confirmed by laboratory results of tribological tests. The laser treatment parameters used, which are shown in this article, did not lead to the appearance of cracks in the micromachined materials. Research has shown that the connections between elements with a properly selected micropattern are characterized by a several-fold increase in the strength of joints, unlike materials without a micropattern. The presented method may be helpful for use as a technology for joining plastics.
