As the 3D printer market continues to grow, machines are becoming more reliable and faster, and key components that determine the functionality of the printer, such as extruders, hot ends and nozzles, are gaining more and more importance.
July 6, 2022 - Canadian company Dyze Design tries to offer a set of solutions for a wide range of machines and has developed high-performance extruders such as the Pulsar or Typhoon. These extruder services range from standard fused deposition manufacturing (FDF) tabletop machines to specialized pellet extruder solutions. By offering high-speed print heads with leak-proof systems, DyzeDesign wants to ensure fast, accurate, and repeatable FDM printing processes.
3D printer manufacturer DyzeDesign
Dyze Design is a Montreal-based company engaged in developing, manufacturing and marketing 3D printer components, mainly heating heads, extruders, sensors and other types of accessories that control the supply and storage of raw materials. The company's mission is to enable people to create the tools and things they need, whenever and wherever they need them. This mission is achieved by developing products that improve the reliability and usability of 3D printers by printing new materials.
In short, we want to be the Intel Inside of 3D printers, positioning ourselves as the leading supplier of extrusion systems for all printers operating on the Material Extrusion (MEX) principle, especially at very high industrial throughput," said Xavier Geremia, Dyze Design's sales representative and account manager. i.e. for industrial and robotic technologies.
Currently, the desktop 3D printing market is still dominated by filament systems, although the use of pellets is very common in the plastics industry, especially in injection molding. the RepRap movement further popularized the use of FDM printers and began to start using filament materials in large quantities in both the consumer and industrial markets. In short, the use of plastic pellet-based raw materials is relatively new to 3D printing, but the advantages are significant, especially for large-format printing and high extrusion rates.
The advantages of pellet 3D printers
Of course, granular 3D printing has its several advantages. First, for the same amount of material, the cost is on average 3 to 4 times lower than filament, and Pulsar targets ultra-large industrial high-speed printers that can extrude up to 2.5 kg of material per hour, resulting in significant cost savings. What's more, filament spools of more than 1 kg are quite rare. High-consumption systems for fine filaments, such as Dyze's Typhoon, require regular spool changes.
Secondly, pellets are a more ecological and flexible solution in the eyes of many industrialists and manufacturers. They can produce their own pellets, especially using recycled materials (so-called "repro"). Finally, pelletizing offers a lot of flexibility in terms of material selection: some polymers do not exist in filament form at all, because their properties do not allow them to be processed, but they can still be extruded to form parts.
The considerations when using pellet feed for printing are similar to those for using filaments, but are more sensitive to moisture. Therefore, it is important to use desiccants to store certain types of materials in moisture-proof containers; moisture is the number one contributor to print distortion. In addition, the use of a pellet delivery system to avoid manual filling of the material pattern is an equally important point to keep in mind.
The advantages of Dyze Design high-speed extruders
In recent years, there has been a trend towards "speeding up" printers (e.g., printers with speeds of about 300 mm/s). This is a good trend, but in reality, it is not useful to increase the printing speed if the extrusion system is not capable of extruding at high speed. In short, even at medium printer speeds, a high-speed extrusion system will greatly reduce print times, because such a system means more material per second. This is especially true because larger nozzles are typically used and the diameter of the lines and layers will be much larger. This is ideal for printing large parts on the increasingly popular large printers (BigRep, Modix, 3DPlatform, etc.).
Obviously, high throughput means a lot of molten material. In high speed printing, especially large format printing, parts tend to warp more because each layer doesn't have time to cool down fast enough. Therefore, it is important to use a good active cooling system, but also to have "additive manufacturing design" logic to ensure that the layers are well supported by each other.
A common disadvantage of high-speed particle systems is that they can only print in "vase mode". Since shrinkage is almost impossible using the screw extrusion principle, the material will continue to flow (bleed/leak) as it moves. In our case, however, our Pulsar uses a leak-proof system in the nozzle that allows movement in the X and Y directions for multi-part printing, or rather is not limited to vase mode.
The Dyze Design extruder's distinctive hot-end part
Today, specialized manufacturers engaged in 3D extrusion are offering a growing number of products that are highly reliable and adaptable to user limitations. This is actually very good news, as it shows the growing interest in additive manufacturing and the ability of extrusion system manufacturers to adapt to all the new challenges and constraints of a booming market. says Geremia: "With this logic, our products are positioned at the very top end of the range, perfectly meeting the needs of users, especially industrialists with more advanced manufacturing and engineering constraints of industrialists. Our extruders are made of 100% metal, can withstand severe shocks or vibrations, and allow for extrusion temperatures of 500°C for printing any polymer on the market. In addition, our systems can withstand high temperature environments up to approximately 80°C and are reliable and durable. Our philosophy is also to provide products that are adapted to the open source environment, allowing each user to use their own ecosystem to meet their needs and challenges. "
Almost all the components of Dyze Design's high-speed industrial extruders Typhoon and Pulsar are designed and machined directly by the in-house production team at the Montreal plant, allowing them to offer the best quality while being sensitive to every constraint.

What things are less late maintenance maintenance, such as 3D printers, a long time without maintenance, there will certainly be some small problems or even big problems, so how to avoid the occurrence of it, the following are a few examples.
1. clean the nozzle motor on time
Whether the gap between the base plate is too small, the residual impurities in the nozzle, the use of material wire and conversion parameters are wrong, etc., resulting in the nozzle blockage, or the material disk winding knotted resulting in the nozzle can not be out of the silk, are going to make the nozzle motor runaway idle, feeding gear and material wire friction will form the slag deposited in the extrusion structure will interfere with the force distance of the wire feed, and may fall into the nozzle inlet, jammed into the nozzle material wire. Therefore, the user is proposed to do a nozzle motor cleaning after 1 month of normal use. If the user to 20 hours a day of high intensity use of the printer, it is proposed to do once every half month to clean.
2. maintenance of the printer optical axis on time
The X-axis and Y-axis (two axes in the horizontal direction) parts of the 3D printer do high-speed operation when printing. In order to reduce frictional resistance and noise, all the optical axes of the printer are greased at the factory. It is recommended that the user find the grease cartridge from the accessory box and wipe a layer of grease on all the optical axes of the printer at an interval of 2 months or when the noise of the printer increases. If the user uses the printer with high intensity, it is proposed to do the optical axis maintenance once every 1 month.
3. maintain the Z-axis screw on time
The Z-axis of the 3D printer is driven by a filament rod (the vertical axis). If after a period of time, the user feels that the noise increases when the Z-axis platform is operating up and down. You can find machine oil or ordinary lubricant to drop a few points on the filament rod from top to bottom, and then enter the control panel and manually manipulate the Z-axis motor to do 10 up-and-down movements to let the lubricant spread evenly to the surface of the Z-axis filament rod.
4. Regular maintenance of timing pulley set screws
The X-axis and Y-axis of 3D printer (two axes in horizontal direction) are driven by synchronous belt to do high-speed operation, and the synchronous belt pulley on the synchronous belt connecting axis is likely to be loosened during the long time of rapid forward and reverse switching. Suggest the user to use the 1.5mm hexagonal wrench to tighten the set screws of all synchronous belt pulleys once a month.
5. synchronous belt tensioning
3d printer after 1 year of use, synchronous belt may occur due to a long period of high-intensity stretching of slight relaxation, interference with the positioning accuracy of the nozzle. At this time, the timing belt needs to be tightened again to position. X-axis synchronous belt tensioning, first disconnect the printhead heating assembly plug, you have to use a 2.5mm hexagonal wrench to unscrew the two screws at the bottom of the printhead positioning aluminum block, the entire printhead module from the bracket to remove. Loosen the locking screws on the left side of the synchronous belt cover from the bottom of the bracket, the synchronous belt will be removed and then pulled tightly into the positioning slot again, lock the screws from the bottom, put back the printhead module and connect the printhead heating assembly plug.
Tighten the Y-axis timing belt, the first 1.5mm hexagonal wrench to loosen the four timing belt pulley set screws on the timing belt shaft, the timing belt near the front door side from the positioning slot, and then insert the positioning slot again after tightening. Push the X-axis platform to the Y-axis near the front door end, use vernier calipers to measure whether the two ends of the X-axis platform is parallel to the front side beam, and finally lock all the timing belt pulley fixing screws.
After the timing belt is retightened, print a 20mm test block to check whether the four sides of the block are vertical. The more likely error when the timing belt is re-tightened is that the two Y-axis timing belts are positioned with deviation, resulting in the X-axis platform not being perpendicular to the Y-axis and the printed test block having deviation in perpendicularity on all four sides. If this problem is found, the positioning of the Y-axis synchronous belts needs to be readjusted.

The solar industry in the United States is booming, with the industry growing at an annual rate of more than 50 percent over the past 10 years, adding to the employment of more than 240,000 Americans. Despite this growth, many people are still hesitant to adopt this green energy source because of the large initial investment required to build solar panels. the advent of 3D printed solar panels may make this green technology affordable enough for everyone to enjoy it. So, how do 3D printed solar panels work and where can we expect to see them in the future?
3D printing is appearing in almost every industry. It was only a matter of time before 3D printing and solar technology were linked. Traditional solar cells start with polysilicon, which is melted and injected with boron to form a semiconductor, then silicon wafers are added to the surface and etched, and electrical contacts are embossed on the surface. From there, each cell can be tested and assembled into a finished solar panel.
3D printing shortens most of the manufacturing steps, and a 3D printer places every layer from the semiconductor ink to the surface to produce cells 200 microns thick, about four times the thickness of a human hair.
If you're looking for a long-term solar solution, 3D printed panels are not the best choice. Now, they're not as efficient as traditional solar panels and won't last as long, but they make up for that lack of longevity in cost. A traditional 21 square meter solar panel can cost you upwards of $5,000, but you can buy 200 square meters of 3D printed panels for about $2,000.
3D printed panels may not last long, but according to industry experts, they can absorb more than 20 percent of the sun's rays and are 50 percent cheaper than traditional panels.
According to the Solar Energy Industries Association, U.S. companies alone added more than 145 billion watts of solar energy to the overall infrastructure in 2017, almost double the capacity installed in 2015. This doesn't even include the thousands of home-based systems installed during the same period. Adding solar to your business over the same period will not only lower your overhead, but it will significantly lower your monthly electricity bill, it will help you become more energy independent and reduce your carbon footprint. It can even boost your profits thanks to tax breaks and incentives from state and federal governments.
If you're looking for a long-term solar solution, 3D printed solar panels are not your best option, at least not yet. If the technology matures for a few more years, we may find that these 3D printed panels will be more efficient and last longer than traditional panels. Making solar energy more affordable could be the first step in the right direction as the American public needs to move away from fossil fuel power to more environmentally friendly alternatives, for sure.
