FDM (Fused Deposition Modelling):
The most widespread 3D printing technology, in which the printer melts plastic filament and deposits it onto the print bed through a nozzle with high precision, building up the required part layer by layer. A huge selection is available in terms of size, material composition, and color, ranging from simple materials to the most advanced high-performance polymers.
Our workshop houses more than 25 such machines, which have been selected in terms of size, processable materials, and printing capabilities to provide our partners with the most versatile production capacity possible.
The size of our machines allows the printing of parts up to 600 mm in one piece from conventional materials, and from special polymers (e.g. PEEK) up to 300–400 mm depending on the geometry.
Since precise manufacturing is a basic requirement in industrial fields, we not only have high capacity, but we also continuously develop and maintain our machine park, thus guaranteeing our partners the proper quality in every respect.
The final result of FDM printing depends significantly not only on the technical conditions, but also on the fine-tuning of numerous settings. Our company has outstanding professional experience in printing settings, so we provide a high level of service even in the case of special surfaces, tolerated dimensions, foreign and dissolvable support materials, fitting parts, or seemingly impossible geometries.
SLA (Stereolithography):
The highest-resolution 3D printing process, with which we produce highly detailed resin prints with an almost perfect surface finish. During the process, the object is also built up layer by layer from a special photopolymer that cures under UV light. Exposure is provided either by an ultra-high-resolution 4K–16K LED display or by a UV laser, which can achieve layer heights as low as 0.025 mm, thereby creating practically invisible layers.
We primarily use this technology for high-quality prototypes and small-series products where no compromise can be accepted in terms of visual quality.
Due to its range of materials, it can be used in many types of projects, from simple presentation models to biocompatible parts or components exposed to extreme heat loads.
In our workshop, 3 different SLA printers strive to meet those needs of our customers that exceed the visual or hardness requirements achievable with FDM printing.
In addition to proper settings and preparation, it is extremely important with these special materials that the removal of supports, washing off the remaining resin, drying, and post-processing of the print are also done professionally. Without these, although the result may appear satisfactory, its chemical and mechanical properties may fall far short of what the material would otherwise be capable of. We pay special attention to the proper execution of these tasks in every order.
SLS (Selective Laser Sintering):
SLS printing is an advanced additive manufacturing technology for parts subjected to mechanical loads, in which a precision laser fuses the shape of each layer in a polymer powder bed heated close to its melting point, thus building the object layer by layer so that it has uniform strength in all dimensions. Its characteristic material is PA12, along with a few other PA variants. This technology compensates for its narrower range of materials and colors with the strength, wear resistance, and outstanding mechanical properties of the manufactured part.
Another advantage of the manufacturing technology is that the support is provided by the plastic powder bed not melted by the laser, so neither its removal complicates post-processing nor do the traces of removal spoil the visual result.
The manufacturing technology is complemented by post-processing and surface treatment procedures so that, as a final result, every customer receives a full-value end product with a uniform texture and sealed pores, which can even be painted or otherwise surface-treated.
The maximum production size is 300 mm, but in every case we individually examine the manufacturability of the geometry.
