Ultimaker Cura 5.0

Ultimaker has announced the latest version of Cura: Cura 5.0! The new version offers a lot of advantages such as higher print quality with finer details and stronger part production in less time.

The slicing engine is the most important part of the software. As it is known, a slicing engine is what transforms a 3D model into G-code and prepares it to be printed. Ultimaker 5.0 offers a new slicing engine with an important feature: variable line width. Sliced files used to use a consistent line width that depends on the nozzle diameter and the setting. Basically, if less noticeable lines are desired, a smaller nozzle was used and vice versa. So, if part of the print was two and a half lines thick, two lines would occur which led to a gap between them. This resulted in errors and inconsistent lines, and thus there were many gaps in a printed part. Because of this, printing took a much longer time and caused vibrations and noise.

Cura 5.0 offers a new slicing engine that unlocks variable line widths. The extremely fine details used to be omitted by the slicer as it was not possible to print them successfully. Ultimaker Cura 5.0 solves this problem with its new slicing engine. In the new version, the width of lines is adjusted, so there are no uneven lines. As a result, parts are much stronger and have finer details. Furthermore, thanks to increased toolpath efficiency, print time also improved. The new slicing engine allows us to improve print profiles, thus printing them faster. Printing time can now be reduced up to 20%. Also, there are fewer gaps between the lines as they are increased and are thinner, giving way to stronger parts.

Setting up the Layer Height in a BCN3D Printer

Setting up the Layer Height in a BCN3D Printer

The first step of 3D printing is called slicing, where the model is transformed by the software into a number of layers via G&M code. In this process, you can set up the necessary changes according to what you are looking for in the model. Speed, temperature, strength, infill, printing time and many different settings can be applied. However, 3D print layer height is the most important in terms of quality and printing time.

• 3D printing layer height

First of all, it is important to understand the working principle of 3D printing. A spool of filament, generally a plastic filament, goes through a hot end and melts at a temperature between 190º and 270º. This molten filament is then transferred to the printing surface in the shape of the first layer, which was divided by the slicer earlier. The fan in the tool head cools the layers down and the next layer is printed. This process repeats itself until the printing is done.

The actual height of each of these layers is called the layer height. You can set up the height on the slicer and it can be altered according to your needs.

• The impact of the hot end size on the layer height

As mentioned before, the hot end melts the filament and transfers it to the printing surface. A hot end consists of three parts: the heak sink, the thermal block and the nozzle. Basically, the filament enters the hot end through the heak sink, melts in the thermal block and goes out of the hot end through the nozzle. The change happens in the nozzle. The nozzle sizes range from 0.4 millimetres to 1 millimetre, which depends on the filament coming out of the nozzle.

So, the bigger the nozzle size, the more material there will be. As a result, 3D print layer height increases.

• Altering the print quality by tweaking the 3D print layer height

The higher the layer height, the fewer layers there will be on the model. However, the layers will be bigger and much more visible, which means the print quality will not be as good. So, the layer height and print quality are inversely proportional. In this case, if we decrease the layer height, there will be more layers. Thus, the layers will be less visible, increasing print quality. However, the layer height cannot be altered freely. There is a recommended maximum layer height, which is half the nozzle size. This prevents us from depositing more filament than necessary. The recommended minimum layer height is quarter the nozzle size.

• Altering the printing time by tweaking the layer height

When the layer height is decreased, the number of layers increases. Then, there will be more printed layers and the printing time will increase and vice versa. If there are less layers, it will take less time.

Jigs and Fixtures

Jigs and Fixtures

When assembling a product, we can’t often use off-the-shelf tools during product development. It is through custom jigs and fixtures that help us get repeatable work. Custom jigs and fixtures can be adjustable, or specifically designed for a certain part, which makes production easier, faster and more accurate. However, producing these jigs and fixtures via traditional manufacturing methods might be expensive and time-consuming. Traditional methods are 100 times more expensive than 3D printing these jigs and fixtures, and much faster. 3D printing helps reach the final design faster, making it easier for engineers to print replicas, thus minimising lead times.

Ford’s engineers in Cologne produced a tool that they can hook at the back of the car, enabling them to position badges and emblems quickly. This tool was 3D printed with tough PLA in two parts on the Ultimaker s5 and glued together later on.

Volkswagen Autoeuropa’s engineers in Portugal developed a wheelgun jig, which helps them to place their wheelgun into the wheel. The part was 3D printed in multiple parts so that it can be quickly replaced in case of damage.

Traditionally, it takes a very long time to attach the pedal to a bicycle as one has to tighten it manually using a wrench. eBike Manufacturing 3D printed a tool using polycarbonate, which fits perfectly around the pedal and holds the nut in place. The pedal can be attached in less than a minute with the help of a drill.

At Ultimaker, several tools, jigs, and fixtures are 3D printed on Ultimaker 3D printers. The main axis of an Ultimaker 3D printer is connected to its motors via sliding blocks. Ultimaker uses a custom-designed pressure fixture that helps assemble the sliding blocks. This tool is 3D printed from XSTRAND™ GF30 PA6 (nylon with 30% glass fiber) which provides strength. It is combined with Ultimaker TPU 95A, which is a soft and flexible material, protecting the sliding block from any type of damage.

Factories may subject jigs and fixtures to high stress or temperature. So, it is important to choose the correct material. Ultimaker provides an open filament system, which offers a variety of industrial-grade materials from any brand, including industrial plastics, carbon, steel, or glass-fibre reinforced filaments. Therefore, you are provided with strong, tough, high-temperature resistant, flexible, rigid materials to choose from. Also, it is possible to have custom-designed filaments specifically designed for your requirements.

With Ultimaker’s dual extrusion 3D printers, it is possible to combine many materials. Many companies prefer Ultimaker Tough PLA for strength, combined with the protectiveness of TPU 95A. Another advantage is that you can use two colours. If you choose to use another colour for the outer surface of a part, the colour of the inner surface will show whether a part is ready for replacement.
