Evektor has extensive and very positive experience with application of 3D printing by FDM technology. We offer our experience with this technology which will help you to reduce development costs and will enable you to increase your competitiveness.
Examples of 3D printing
A functional prototype part installed on the airplane for the purpose of verification during flight tests. Length of the part is about 1 m.
Grill of air outlet from the engine space
The outlet grill was installed on the airplane during flight tests of engine cooling system. Grill dimensions: about 350 x 230 mm.
Model of unmanned helicopter
The model of unmanned helicopter was made from several parts connected by means of adhesive bonding. After that the surface was protected by paint coating
Functional prototype of the rotor hub
The rotor hub was assembled from several parts and equipped with other parts produced by “classical” manufacturing process. This rotor hub served for the purpose of design concept verification.
Various parts produced by FDM method
FDM technology is especially suitable
- For production of functional prototypes of plastic parts with mechanical properties close to real pressed parts.
- For parts which will find their application for production of mock-ups and visual samples.
Possibilities and advantages of FDM technology
- By means of this technology it is possible to produce practically any shape, including functional non-demountable assemblies.
- The technology enables production of mechanisms and their parts.
- Fast creation of parts from delivered 3D models – you will obtain a functional part within hours up to days (depending on complexity and size of the part).
- The materials used for production of parts by FDM method are ABS plus, ABS-M30, PC (thermoplastic polycarbonate) and ULTEM 9085.
- FDM is an advanced technology. It will be our pleasure to give you more information about this technology during your visit to Evektor. We will also show you real parts produced by this technology.
Technical parameters of parts produced by FDM technology in Evektor
- Maximum dimensions of parts are 914 x 609 x 914 mm (Bigger parts can be produced from smaller parts by adhesive bonding. Very high accuracy and strength of bonded parts.)
We accept data in the following 3D formats
- Catia V5, Catia V4, Pro/ENGINEER, STEP, IGES, VDA and STL (with sufficient accuracy).
Materials available for manufacturing
|Thickness of layer||ABS-M30||PC||ULTEM 9085|
Specification of the used materials
- By 5 – 70% stronger than standard ABS
- Higher tensile strength, impact resistance and bending strength
- Strength of connection of individual layers is significantly higher - longer service life of parts
- Multipurpose material: suitable for production of functional parts
- ABS-M30 specification can be downloaded (PDF)
- The most widespread industrial thermoplastic material
- Accurate drable and stable – suitable for load carrying part
- Excellent mechanical properties and thermal endurance
- High tensile strength even for higher temperatures
- PC specification can be downloaded (PDF)
Thermoplastic ULTEM 9085
Mechanical properties of resulting product from ABS plus material
Values were determined by test that defined the minimum theoretical strength. The maximum strength was reached at the defined cross-section. This strength isn’t maximum strength of material which is by up to 40% higher than that of standard ABS. Maximum strength would be reached in the thinner cross-section where fibers would be put in layers in the loading direction only. Owing to the fact that most profile parts (pressed parts) are of a general shape and the direction of fiber is variable in individual sections and lower thickness of the wall is applied, the strength of a real pressed part will be more likely in the upper half of strength range determined by tests..

|FDM in layers***
|Strength of model made by FDM is, in comparison with standard ABS, in the following range:
||60% - 114% (140%)
||67% - 103% (140%)
||82°C (without loading up to 96°C)
|The model is set to position for printing with regard to:
||1. Required strength
2. Required quality of surface
3. Time of printing and model price
