Femtosecond laser-based 3D multiphoton polymerization is superb for fabricating micro-scaffols with complex functional architectures from any relevant material.
Produces high-resolution (up to hundreds of nm)photonic devices in the visible and IR spectrum. Minimize aberrations or exotic light distributions, such as Bessel beams or optical vortexes, through arbitrary shape profiles of microlenses surface suitable for optical applications.
The Industry 4.0 paradigm makes it a necessity to track the functionality of each single device and to avoid counterfeiting. This is critical in the medical industry when a patient's condition is on the line. To combat this, cloud based individual tracking systems and highly advanced marking techniques must be employed. The Nanofactory allows the production of QR codes down to several micrometers on arbitrary material. Devices suffer no thermal damage or other side-effects outside of the marking area, crucial for maintaining functionality of medical device / components after marking.
When liquid is confined within extremely small spaces (several hundred micrometers), non-trivial behavior can be exploited for drug development/production, life-sciences, fundamental research, and more. Amplified femtosecond lasers have been shown to be extremely capable in producing microfluidical components. Realized through both additive and subtractive manufacturing channels, arbitrary free form integrated elements and bonding can be realized with only one laser micro-machining setup.
With the natural trend of downsizing the mechanics in modern technology, it increasingly important to reduce the size of the mechanical elements. 3D femtosecond micro-manufacturing with the Nanofactory allows sub-micrometer scale elements to be produced. FS pulses allow the possibility of producing elements with a diverse range of materials, from polymers and glasses, dielectric crystals, or metals. Gears, springs, cantilevers, and other classical elements can be easily produced.
industrial material processing is completely reliant on lasers and light-based solutions on all dimensions of processing. Functional surfaces are incredibly important in fields ranging from medicine to space exploration. The surfaces created with fs pulses can be easily made both repelling and adhering. wide range of applications, from tool manufacturing, anti-bacterial self cleaning surfaces for medical implants, surface friction reduction with water, anti-icing properties, and much more can be achieved.
Diverse femtosecond processing regimes provide a wide range of benefits. Additive manufacturing of conductive medium becomes possible, allowing true 3D electrical components to be created. Cutting or scribing of electrical contacts is also possible thanks to the minimal heat effects from femtosecond laser processing. The laser can also be used to produce high precision substrates for electronics, cutting any trenches, holes, and any other pattern.

Femtika was born as a spin off company from the Vilnius University Laser Research Center in 2013 by a team of experts with a portfolio of research and development in 3D laser precision micro processing.
Project is funded by the European Regional Development Fund, project Nr. 01.2.1-LVPA-K-856, project duration: 2020-2022.
Focused femtosecond radiation allows to selectively induce arbitrary refractive index modulations inside any optical fiber. Additionally, multiphoton polymerization can be used for easy assembly free fabrication of multi-component micro-optical elements on tips of optical fibers allowing to forgo currently used complicated gluing-based multi-step process. Combined,
these two processes will pave the way for a revolution in on-demand fiber-based device manufacturing.
The end goal of the project will be two femtosecond laser-based workstations – one for Brag grating integration into optical fibers and second one for fiber-tip optical element manufacturing.
Prototyping of innovative multifunctional industrial machines for the production of complex microfluidic devices
The aim of the project: to acquire knowledge and form concepts of their application for the development of new microfluidic products for medical and biomedical purposes. Based on them, to develop an efficient technological process for the transfection of microfluidic perforator molecules into cells and the formation of a micro (nano) microfluidic sensor for slow liquid / gas flow. To create prototypes of devices, which will be able to realize the process of laser micro (nano) forming for the layout and production of the mentioned microfluidic products.
During the project implementation period, the following research activities were performed:
1. Investigations of design characteristics and technological concepts of microfluidic channels for cell transfection and fluid flow measurements;
2. Investigations of design parameters and forming concepts of micromechanical components required for cell perforation and fluid flow measurements integrated in microfluidic channels.
Possible essential constructive technological solutions of microfluidic channels were modeled, tested and evaluated during the activity. The optimal solutions have been chosen both in terms of technology, ie simplicity of formation of structures, economy, and functionality in terms of functionality in a medical device. To ensure the functions of the cell perforator, the optimal concept of knives integrated in microfluidic channels was chosen, in the case of a flow meter – the concept based on the use of an electromechanical valve. After refining and finalizing the 3DLL process parameters, it became possible to test and more precisely define the mechanical and optical properties of microfluidic channels and the elements integrated into them, and to use adequate numerical modeling for their design. In this way, it was possible to resolve the scientific uncertainties unknown before the start of the activity.
The objective of project is to develop, test and demonstrate industrial-grade solidstate 2-3 kW-level fs laser with parameters suitable for metal surface patterning for enhanced surface repelling and/or adhesion properties, leading to increased durability, self-cleaning, anti-fouling or enhanced tissue attachment applicable in industrial settings.
FemtoSurf industrial-grade 2-3kW-level fs laser will be integrated in proposebuilt optical chain enabling multi-beam processing (100+ simultaneous beams) with individually tailored spatial distributions in each laser spot, integrated into a fully automated processing setup for efficient patterning arbitrary shaped metal components.
