3D printed cw paddle

New 3D Printed CW Paddles by CR6K (video)

One shortcoming we had at SZ1A was the lack of a dedicated CW Paddle “key” for every station operating position. Usually operators would bring their own. But we wanted to have our own “keys” in for the station, as a matter of honor! Most operators use the computer for the entire CW contest. However, everyone wants to feel the security of having a CW paddle key. Operators will often want to manually send something: for example a TU, or CFM, or even a couple of dots…without using the PC.

Unfortunately, CW keys / paddles are expensive. The cheapest will start at around €100 and at that price it often won’t be very good. Usually, more than €150 is needed to purchase something satisfactory. So far we have only owned one Bencher ΒΥ1, donated by Kostas SV1DPI and we definitely need more.

Recently, on the web one can find various designs of CW Paddles & Keys that can be… printed! 3D Printers have entered our lives for good. You might have already heard in the media that someone even printed a house! So why not a CW Paddle or Key? Due to the lack of a 3D printer but mainly because we wanted something tried and tested, we chose to buy a ready-made paddle.

We ordered three to cover the fully equipped stations. The project was funded by Vassilis SV1BJW who made the required donation. Filipe offered a fourth CW paddle as a gift for SZ1A! We thank them both!

So we turned to CT1ILT (CR6K), a very good and well-known contest operator, who makes and sells CW keys printed on a 3D printer. Filipe sells these keys for just €40 each. We ordered three to cover the fully equipped stations. The project was funded by Vassilis SV1BJW who made the required donation. Filipe offered a fourth CW paddle as a gift for SZ1A! We thank them both!

About a month and a half after our order, the CW paddles arrived at the station. Before the order, we were worried if we made the right choice was. We were afraid that they might be a very cheap construction, therefore, of poor quality.

Would they handle contest conditions? Could someone key fast enough with them? Would they look good? or would they look like cheap plastic?

First of all, they are beautiful!

The colors were very nice! And the overall finish and their exterior was excellent. In fact, the colors chosen by Filipe made them look even better. They also have the station callsign engraved on them! Amazing! They definitely pass this test!

The biggest problem with Morse keys is that they have to be relatively heavy so that they do not move with the force exerted by the operator. A normal key’s weight is often from 1200 to 1500 grams! How much can a plastic counterpart be? We weighed them!

Here, friends, was the weak point: only 148 grams! Compared to the 1. 5 kg that BY1 weighs, it was an issue. Of course, Filipe had warned us earlier that it is light and requires a metal surface to “stick” on. These keys have an innovative solution to the specific stability problem, they come with 4 neodymium magnets installed in its base. Therefore all you need is a metal surface to place them on to make them stable.

These keys have an inovative solution to the specific stability problem, they come with 4 neodymium magnets installed in its base. Therefore all you need is a metal surface to place them on to make them stable.

And now what;

We cut a galvanized metal plate 8 mm thick in the dimensions of the key, approximately 10×9 mm (cost of only €6 for all 4). At the same time, we bought some antislip PVC matting (just €1 for a large piece). By the way, PVC matting is perfect for all keys and stabilizes them very well.

We glued the PVC to the bottom of the metal plate, and the CW Paddle – Key sat on the top. The result was perfect! The controller is completely stable and clearly better than the BY1!

The key’s contacts can be easily adjusted, as well as the exerted force required by the operator. They use neodymium magnets and not on coil-spring returns. One thing that is missing is the cable, you’ll need to either make or buy it. This isn’t an issue since most keys are provided without a cable. These key’s have a standard 1/8″ female stereo plug that you can easily connect your cable to.

We used the keys during the CQ WPX CW 2021 contest. Everyone’s impressions were more than positive. The keys served 100% of the purpose for which they were purchased. Everyone agrees that their value for money is absolutely excellent. They can definitely not be compared to keys that cost maybe ten times more. However, they are very good and look good in the shack too, which is always important to most Radio Amateurs. They also seem to be quite durable.

Everyone’s impressions were more than positive. The keys served 100% of the purpose for which they were purchased. Everyone agrees that their value for money is absolutely excellent

Some have already expressed interest in buying one. There are reservations about the contacts: it is just a screw, neither platinum nor gold. Ok, well it’s just a screw, so if it breaks at some point you can replace it easily and at almost zero expense. One observation is that although the metal base does not move, the key does in some cases. This happens when sending under high speed and the stress of the operator is greater, they may exert more pressure, moving the key. The operator may feel more comfortable by securing the key by holding it with their hand, otherwise, it may move a little and you might miss a dot. You will see in the video that this happens sometimes but not always…

To solve this issue entirely we will add 1-2 neodymium magnets more, so that it is secured even more to the base and it will be perfect!

How 3D printers work

The basic principle of a 3D printer is layer-by-layer application of material. At the same time, you can print anything: concrete, living cells, plastic, chocolate. 3D printing is simply the principle of creating an object, along with any other method of production. nine0003

The main use of 3D printing in life is prototyping and creating unique objects. When prototyping, you can print several versions of a product and choose the one that turned out better than the rest. There are industrial enterprises that print plastic items, but it is too early to talk about the widespread use of 3D technology. She has two problems: slow production speed and not high enough quality. Indeed, you can print anything you want, but now it is not economically feasible to launch such mass production, Alexander Kornveits explains. nine0003

On the other hand, 3D printing can be used to create unique, design elements, sculptures, monuments. For example, in Moscow you can see printed sculptures like “Girl with an oar”. Often, such sculptures are additionally processed to give the appearance of a monument we are used to, made of marble or plaster.

Prospects for 3D printing for medicine

In the medical industry, the most active use of 3D printing is in dentistry. If you go to the dentist now, you will be faced with a 3D scan; or you will be offered 3D printed aligners. This is no longer prototyping, but the creation of final products or blanks for final products. nine0003

Bioprinting - organ printing - is currently under development. First, a cell of a damaged organ is taken from a person - skin, liver, kidney. After that, the cell multiplies in a special solution, and then, using a special bio-3D printer, the organ that needs to be replaced is produced. In this case, layer-by-layer stacking of living cells on top of each other also occurs, resulting in living tissue. The ability of such an organ to take root is much higher than that of a donor organ. According to the guests, this technology will be able to be used to treat specific patients in 5-10 years. nine0003

Printing a house: 3D printers in construction

Building 3D printing developments are very popular because there is a shortage of housing in the world. In Russia, this area is also developing, but many construction companies work abroad, since there is a higher demand for 3D technologies, Sergey Nefedov explains. For example, the founders of the California startup Mighty Buildings are from Russia. The essence of 3D printing is that it is effective where labor resources are expensive. For example, Australia and New Zealand have a norm that allows construction to be done only for 6 hours a day. This is based on the loads that a person can withstand. The cost of housing in these regions is very high, so it is advisable to replace a person with a robot. nine0003

The problem with 3D construction is that automation and robotization of this industry has not yet occurred, in contrast to the automotive industry, where production is divided into separate operations. 3D building at the moment is a layered construction of walls, which is not difficult to handle. The portal system allows you to print the entire house: first, a portal is built that is larger than the house in size, and the building is printed inside it. But at the stage of finishing and engineering, problems begin. If a company can streamline all this R&D and replace people with machines, then it might work. nine0003

3D printing eliminates the human factor: for example, building mix will always have the right consistency thanks to the settings. But in Russia, all cities are growing skyward, and 3D printing technologies are more applicable to low-rise construction. Unlike the markets in the US and the Netherlands, our market is still unfavorable for 3D construction.

The future of 3D printing: orthopedic insoles and space colonization

The main advantage of 3D printing is customization, the ability to create a unique product, says Kornweitz. For example, the creation of orthopedic insoles will soon be actively developed. Another example is the frames and lenses of glasses, which take into account all personal characteristics. That is, the entire development of 3D technology will take place in areas where a personalized product is created for each individual person. nine0003

The second promising direction is to use 3D printing where there is a gain in time and a shortage of something. For example, if there is a shortage of housing in the country, and classical technology does not allow it to be repaid, Sergey Nefedov adds. During the pandemic, a similar situation occurred with a shortage of valves for ventilation. 3D printer owners around the world have teamed up and started printing ventilator parts and sending them to hospitals. The same thing happened with the seal of PPE for doctors.

Finally, 3D printing is essential for colonizing other planets. It is impossible to predict what may be needed during a space mission, but if there are materials and apparatus, then at any time you can print what you need. nine0003

17 real 3D printed buildings

3D printing technologies are developing extremely fast and are being used in various areas of human life. nine0003

Recently, much attention has been paid to the printing of buildings, and printed houses are increasingly appearing in recent years in different countries of the world - in the USA, Saudi Arabia, Mexico, France, Russia, the United Arab Emirates and others. I have prepared a list of existing 3D printed buildings for 2020.

What is a 3D printer for construction.

Today's 3D construction printers differ in designs and wall construction methods. The most common printers are portal construction, two- and four-support construction, based on a manipulator arm or a circular design. The equipment allows you to create small architectural forms and elements of structures for their subsequent assembly on site, or allow you to print the entire building on the construction site. The height and dimensions of the printed building depend on the specifications of the printer being used. nine0003

How the printing process works.

The extruder extrudes a fast-hardening concrete mixture with various additives. Each subsequent layer is applied on top of the previous one, due to which a vertical structure is formed. The concrete layers below are thus compacted, thereby increasing their ability to withstand the next layers, and hence the entire weight of the structure. To strengthen the structure, it is reinforced, which can be both vertical and horizontal. The laying of the horizontal armored belt is carried out between the layers, the vertical reinforcement is installed after the composition has hardened, and then it is poured with concrete. nine0003

Advantages of 3D printing over other construction methods.

3D printing of structures opens up great opportunities for construction and related industries. Practical application has revealed the following advantages of additive manufacturing:

• It removes the limits from the imagination of designers and architects who design buildings, as it provides opportunities that are not available with the construction methods we are used to.
• High speed of construction of buildings and structures. nine0066
• Complete process automation.
• Low power equipment.
• Significant savings compared to conventional construction methods by reducing labor and energy costs and accelerating construction time.
• The formation of waste building materials is completely eliminated.
• Minimization of human intervention in the construction process not only allows building in places inaccessible to people, but also in ordinary areas eliminates the human factor and reduces the likelihood of error. nine0066

1. June 2014. China. Chinese company Shanghai WinSun Decoration Design Engineering Co presented houses built using 3D printing techniques in an industrial park in China's Jiangsu province. A total of ten houses were created, each of which cost a little more than three thousand pounds sterling. Over the next ten months, the technology improved and the company produced several different types of buildings for the exhibition, the tallest of which has five floors. nine0003

2. August 2014. USA. The company Totalkustom Andrey Rudenko printed the lock. The printing took a total of 2 months. The machine's printing speed was 50 cm in 8 hours. The main part of the castle, measuring 3m x 5m and 3.5m high, was printed as a single unit, and the towers were then printed separately.

3. July 2015. China. Chinese company Zhuoda assembled a two-story house in record time. The modular home, made up of six 3D printed modules, was assembled on site in less than 3 hours. Of course actually about 90% of the work was carried out in the company's workshops, and on the site they were only assembled into a single building.

4. September 2015. Philippines. The company Totalkustom Andrey Rudenko built apartments on the territory of a hotel in the Philippines, 10.5 m x 12.5 m in size and 3 meters high. The building was built using local materials - sand and volcanic ash.

5. May 2016. UAE. Chinese company Shanghai WinSun Decoration Design Engineering Co printed prefabricated structures for the subsequent assembly of an office building in Dubai. The area of ​​a one-story building is about 250 square meters. m.

6. March 2017. Russia. Apis Cor introduced the first 37 sq. m.. The printed house has an interesting shape, but as the participants themselves say: this is just to show the flexibility of printing technology, the shape of the buildings can also be the usual square. Compared to other construction 3D printers, this printer is very compact (4×1.6×1.5 m), weighs 2 tons, and can be easily transported to the construction site. nine0003

7. October 2017. Russia. In Yaroslavl, the company Spetsavia presented the first residential building in Europe and the CIS, built using construction 3D printing technology. Construction of the house began in 2015. The box of the building was printed by a portal printer piece by piece and then assembled on the foundation in one month in December 2015. In the summer of 2017, the roof was completed and the bulk of the interior finishing work was carried out.

8. March 2018. France. nine0084 Yhnova presented a five-room one-storey house with an area of ​​95 square meters. For its construction, the engineers used a large manipulator, at the end of which an extruder for polyurethane foam is fixed. While working, he applied the foam in accordance with the 3D model of the building loaded into it. After applying the foam, the builders periodically filled the erected part with concrete, and also inserted the frames of doors and windows.
