CD3D cooperates with Technology Applied – the largest Polish service company that is able to make 3D prints in virtually any additive technology. The company’s offer includes the production of parts using the SLS method (Selective Laser Sintering – sintering of powdered plastics with a laser beam). The largest 3D Technology Applied – EOS printers allow for the production of parts with a maximum area of up to 340 x 340 x 600 mm.
Technology Applied offers a service of additive manufacturing of very precise prototypes and final parts, both single copies and production series.
SLS (Selective Laser Sintering) technology is one of the industrial 3D printing technologies that allows for low-volume production of prototypes as well as usable and spare parts. The technology, by selectively bonding polyamide powders with laser light, allows for the creation of functional elements with increased strength properties.
The industrial SLS technology allows for the production of elements from polyamide-based materials. The restrictive technological conditions of the 3D printing process allow for the production of elements with high mechanical strength and dimensional accuracy.
The service of 3D printing in SLS technology is a comprehensive solution that is an alternative to classic production methods. It is an optimal solution in situations where:
In the proposed 3D printing service in SLS technology, it is possible to 3D print from the following materials:
PA12 (EOS PA220) – the most popular material for 3D printing in SLS technology, allows for the implementation of a number of applications due to increased strength properties and work under cyclic loading. It is the most universal material for 3D printing in SLS technology – it can be used to make prototypes, utility items and functional parts. The elements are resistant to chemicals. Elements made of polyamide powder enable operation at elevated temperatures – up to 50 ° C.
PA12 has a food contact certificate in accordance with the European Directive 2002/72 / EC (except for alcoholic products) and a biocompatibility certificate EN ISO 10993-1 and USP / level VI / 121°C.

The default color of PA12 is white, however, finished parts can be dyed any solid color. Technology Applied has two methods of dyeing – dip and spray coating. In the first case, the dye penetrates the surface of the 3D print, making it more durable, however, the color palette is limited. In the case of varnishing, it is possible to choose any RAL color. The sprays used are of the automotive class.

EOS PA3200 GF – a material based on polyamide, enriched with glass microspheres, which makes the material more stiff and durable. Resistance to abrasion and the ability to work at elevated temperatures makes the material ideal for the production of rigid parts and components working cyclically or in a high temperature environment. In addition, the elements allow easy processing (drilling, grinding, drilling).

PA2241 FR – specialist material based on polyadmide, fireproof with increased non-flammability. Dedicated to the aviation industry and the implementation of specialized electronic and microelectronic applications. Flame retardant material in accordance with UL94 V-0, aviation grade fire retardant FAR 25.853. It does not contain halogens.

Alumide – a material based on polyamide with an admixture of aluminum. The material, apart from increased stiffness, is characterized by a characteristic gray color. Finished details can be further processed, e.g. ground and polished. 3D printed elements made of Alumide can work in conditions of increased temperature, they show good thermal conductivity. Additionally, they are characterized by a high sinter density.

Elements manufactured in SLS technology are characterized by a characteristic, slightly porous structure – elements are sandblasted after 3D printing. As part of the 3D printing service, we offer the following post-processing services:
Depending on the type of item, the time and cost of implementation may vary.
The advantage of using the 3D printing service in SLS technology is the ability to implement elements that are not available using other manufacturing technologies. The advantage of SLS technology is the fact that it enables the quick implementation of functional elements with complex geometries.
