CASE STUDY:

USAGE OF CPE HG100 IN COMPANY LYOTRADE

Company Lyotrade Freeze Dryers, s.r.o. is a young company that introduced its first lyophilizator of own construction two years ago. Lyophilized food is available in a wide range of shops; however, their origin is unknown. Most of those grocery is lyophilized in India and imported through German companies. Lyotrade wants to change it.

Their mission is to provide farmers and processors with lyophilizer so that they will be able to provide information on how food has been produced, how it has been treated and what it contains.

Lyotrade was looking for a material suitable for improving the shelf system where food trays are stored during the lyophilization process. Some materials are insufficient and crack after a few freezing cycles. Others are so fragile that they cannot withstand a deep vacuum and the air enclosed in the print infill tears the component wall.

The most suitable solution is CPE HG100 developed by Fillamentum. Printing quality is guaranteed by a high-quality manufacturing process that fulfill a thickness tolerance of 0.05mm. Fillamentum materials are designed for professional printing due to their high-performance properties.

The CPE HG100 is supplied with a food contact certificate. This material is remarkably strong and tough. It is very hard to break it. When printing with CPE HG100, there is no need to cover the printer and there is almost no warping.

Due to a production of few lyophilizer per year so far, this Czech company does not have too high demands on the quantity of components. In the product chamber of the device, temperatures of up to - 45 ° C dominate, and it is also a food store - the required material needs to be resistant to both, low temperature and deep vacuum processes. CPE HG100 meets all of these.

During development of the device, which is about to be user-friendly and cost-effective, it is necessary to constantly invest in prototype parts, whose future in the project is often unclear. The company is often looking for a supplier who would be willing to produce few units at a reasonable price. A recurring problem is the minimum order of thousands of pieces. Such testing and then tuning of other and other versions of the component is not only time-consuming but also financially demanding.

A company of 3 members, such as Lyotrade is, is unable to create a full-time job position of a printer and therefore appreciates the easy printing of CPE HG100. Details such as thread can be printed from co-polyester as easily as PLA, which is not the case with PET-Gs of various manufacturers, for example.

COST SAVINGS:

In terms of savings, we can compare, for example, the component - a simple cap - to cover the thermostat of the heating blanket. The cap is also a part of the lyophilizer.

Demand from external producer

150 Eur for prototyping + 12 Eur / piece when producing at least 100 pieces

3D printed with Fillamentum:

Used material: CPE HG100

One piece of thread takes about four meters of filament, which costs no more than 0,05 Eur for piece

After good experience with CPE HG100 by Fillamentum, Lyotrade also began to use other materials of this Czech brand. Rather, we used PLA materials of different manufacturers for decoration elements or markings, but after trying PLA Extrafill we decided to stay with this material. The Traffic Black is truly credible and rich black and, like Traffic White, does not leave undesirable artifacts on the surface of the last layer.

CASE STUDY:

USAGE OF FILLAMENTUM MATERIALS IN ROTORAMA

“The printed frame gives us a clear picture of how the frame will look like. It’s all clear and more graspable than on a computer model. The main advantage of 3D printing is the cheap production of unit pieces. The parts, that we print, change very often. Because we print everything ourselves, we can have the necessary piece in hand in just a few hours.”
— Jiří Fiedler, Rotorama

Rotorama is producer of FPV racing drones. These drones are about 25 cm in size, weighing around 500 g and can fly at speed of up to 160 km per hour. 3D printing is here used for printing accessories such as camera holders, antenna holders or drones’ fins. In some cases, the propeller protectors or even a whole shed are printed as well.

Fillamentum, a producer of high-quality filaments, offers solutions for flexible production and fast prototyping with an emphasis on high utility properties that predetermine professional printing. Rotorama employees use flexible materials such as Flexfill TPU for 3D printing. Each hardness, Shore 92A and 98A, is used for something a slightly different. Flexfill TPU is a highly flexible, elastic material with excellent mechanical properties. It is highly durable and has excellent adhesion between layers.

Another integral part of the drones are the frames that Rotorama designs and prints itself. In production, prototypes are first printed in ABS Extrafill by Fillamentum and then cut out of carbon which is more expensive and the production is very difficult. “The printed frame gives us a clear picture of how the carbon frame will look like. It's all clear and more graspable than on a computer model,” says Jiri Fiedler. The ABS material is ideal for the production of the first functional samples before mass production. It has excellent mechanical properties and it is easy to print even in details.

The printed frame model is fitted with other components and then is tested. If the model is in order and meets the requirements, several carbon prototypes are cut and further tested, especially durability. As a standard, 1-2 universal holders are printed for the frames. Customers can print the rest themselves or on demand.

Rotorama uses 3D printing technology mainly for flexible production and fast prototyping. Usually, up to tens of units are printed from each part. The components used for drones often differ in shape. Each antenna and camera have a different shape and each pilot requires a different camera tilt angle. Thanks to 3D printing, each part is basically tailor made for the needs of the company or their customers. They can choose from a range of models that meets their requirements.

CASE STUDY:

USAGE OF FLEXFILL TPU IN COMPANY DAIKIN


Daikin Device Czech Republic s.r.o. is one of the worlds’ leading manufacturers of air conditioning equipment. For over than 90 years Daikin brand has been synonymous for high quality air conditioning for private, commercial and industrial purposes.

On one of the assembly lines in Daikin in Brno, it is necessary to mark two complex-shaped covers with serial number and 2D serial number code. During the marking annoying noise, which breaks the noise limit (up to 85 dB) is generated and it affects the well-being of the workplace and the concentration of the operators.

The solution is a production of an object that would eliminate noise during marking. Additive technology FFF shown up as the most advantageous option. The main reason for this decision is the complexity of rubber machining of such complicated shape and the high cost of creating a mold for molding the jigs.

One of the requirements is to print objects that must damp the noise and the vibration occuring during marking. In the same time, they must be resistant to wear. Considering all of these, Fillamentum has offered its Flexfill TPU 98A and Flexfill TPU 92A materials, which are flexible with good wear resistance. The Flexfill TPU line is characterized by good mechanical properties, flexibility and oil resistance. Another goal was easy processing and simple printing, both of these conditions have been also fulfilled with Flexfill TPU.

After printing and post-processing of the parts, the damping jigs were tested in serial production and the level of noise at working place was measured again with usage of sound-level meter. With Fillamentum materials and additive manufacturing technology, the hygienic noise limit has been reached. Positive effect on the noise level was caused by the choice of softer material Flexfill TPU 92A with hardness of 92 Shore A. Overall, the sound level was reduced by 5.9 dB to 80.7 dB.

It is interesting that originally 3D printing and the use of Fillamentum materials were intended only as a temporary solution. The printed items have been using in the production hall for two years now and during that period over 200,000 pieces of covers were made.
