Why We Need to Scale Up Breathing Equipment Production Using 3D Printing Machines for COVID-19?

If a patient is challenged in breathing on his own, medical professionals attending to his aid would resort to the use of a mechanical ventilator.  Ventilators are pieces of equipment that will help ease up their respiration since they are specifically designed to help someone breathe on their own. 

Modern design of ventilators usually come with a tube and pump machine. Healthcare professionals will be sliding this tube into the windpipe of the patient to help in controlling and regulating airflow to his lungs. COVID-19 patients who are critically ill due to the coronavirus will be in dire need of such devices, respirators, to help them keep on breathing.

Situations described above are putting a great amount of pressure on hospitals and healthcare institutions where the vast majority of which are currently brimming with disproportionate numbers of patients. Most of the time these hospitals are handling a huge number of patients, far greater than what they can actually accommodate. 

As of this writing, the US reportedly has at least 170,000 ventilators available. Despite that, the American Hospital Association is anticipating that the COVID-19 patients who are going to require intensive medical attention and treatment will be escalating to a minimum of 960,000. 

With this in mind, we understand the crucial need to slow down the virus and its spread so as to ensure that not every single patient will be in desperate need of medical attention at the same time. 

Nevertheless, we need to double time on our production efforts for ventilators considering the fact that containing the coronavirus is proving to be much harder than earlier anticipated. This is vouched for by recent events. 

With this scenario in mind, can we take advantage of 3D printing machines to scale up our production for this type of medical equipment?  

3D Printing Machines and Scaling Up the Production 

3D printingExploiting 3D printing technologies in our global situation now will put us all at a greater advantage. In no time at all, medical equipment manufacturing companies will be empowered and enabled to produce the respirator equipment we have an urgent need for. 

But it is much harder when it comes to scaling up its production. 

In Italy, like for instance, they began to mobilize a handful of medical equipment companies and charged them with 3D printing a few dozen valves to be used in intensive care respiratory units. The said valves are a primary component that will link the oxygen mask to the ventilators.  

The Italian design company that was delegated to create the valves and their digital files, its CEO Cristian Fracassi, explained that they were able to act fast because they utilized 3D printing machines for the project. It actually allowed them to test out a small production first which would be nearly impossible if they will do so on an industrial scale. 

In the UK, the manufacturing team behind LCD 3D printers, Photocentric, disclosed that they carried out an overnight test for their 3 large-format machines. It allowed the printing of an estimated 600 valves. 

In addition to this, they also divulged that they can turn 40,000 printed valves in just a week’s time — which would mean they will 3D print for 5 straight days, and that is 24 hours a day. With that level of production capability, they’d be able to reach out to local hospitals and similar health care institutions that are in dire shortage of it. 

Photocentric further explained that they made use of the open-source valve model that can be found on GrabCAD. Then, with the help of their current SLA machines, they were able to successfully vertically print the valve as tightly as they could on the bed without any need for external support mechanisms.  

Naturally, these devices will need to get approved first. But in the days coming, we will witness how these devices will be deployed.  

 

Catering Equipment Repairs are a Necessity: Here’s Why

Exit Signs: Which Type is Best for You?

Every industrial or commercial structure requires signage to designate secure exit points in the situation of an emergency. With the assortment of choices sold today, the issue becomes, what are the pros and cons for every kind of signage and just how does that apply to certain circumstances?

Ultimately, the determination lies with the contractor and the owners in charge of the construction, but you will discover a couple of suggestions to assist in making the last determination. Considering the four primary types of exit signs on the market, the decision may be done a lot simpler.

Different Types of Exit Signs

Photo-luminescent 

Photoluminescent signs are in the mid-range of rates as they’re first supply cost. Nevertheless, the installation expenses are small as no wiring is needed by them and are easy to set up with only a screwdriver. As basically being shine in the dim signs, they reduce more costs by saving electricity from light throughout the day as well as light themselves when it can become dark. 

They’ve no maintenance costs for twenty-five years or even much more on average, which makes them probably the most economical signs offered in the long term. Photoluminescent signs are made in a multitude of colors and designs to match some decor as they start to be very popular with contemporary builders as opposed to the other signage choices for many scenarios.

Incandescent Signs

Traditionally lit filament-based signs are probably the least expensive of signs to purchase, however, the most electricity is used by them and then need maintenance of switching out the bulbs as well as batteries. They may be complicated to set up with the requirement of an electrical line and the setting up of additional framing to make a stud where required for a junction package to service the signal. The good aspect of incandescent signs is that with their two-energy supply they basically fail evidence in an urgent situation, assuming the repairs and maintenance schedule continues to be maintained.

emergency exit sign

LED Signs

Although use LED exit lighting rather than standard light bulbs, led signs are like incandescent. This leads to energy savings after a costlier buy and installation price. They will need much less upkeep as both the batteries and bulbs run longer, nonetheless, the rarely required maintenance might call for a special part or maybe specialist. As they acquire in recognition, LED exit indicators are available in a wider variety of colors and styles to complement the structure, while incandescent signs are going out of the design and are starting to be available in just a generic ascetic.

Tritium Signs

Tritium indicators are arguably the most technologically advanced of the four forms of signs. Self-driven by radioactive material inside of glowing tubes, these signs are hung as a photo wherever they might have to be. They need minimal maintenance other than an unexpected recharge every 3 to 6 years, though they could be costly to dispose of as a result of the remaining radioactive substance after they use out. Tritium signs are hardly ever used any longer due to the environmental issues of the radioactive material, and thus simply are available in one color along with a very minimal design selection.

exit

No electricity is required by photo-luminescent signs and very easy to install, most affordable signs to use. There’s no setup and no maintenance cost and they also keep going for a longer time when compared with other kinds of exit signage or maybe emergency exit indication as well as escape path lighting.

What is a Samson Plasma Table?

You might need to know more about Samson plasma tables if you are going to work on a particular fabrication project. Plasma tables are considered as robotic tables, they incorporate the use of a CNC plasma cutter which is usually held by the hand.

Plasma cutting tables are a ubiquitous tool in every major machining shop in the country. They usually come with a wide variety of offered usable and functional features, besides they are easy to maintain also. So, what are some of the usual features being looked for by machining/fabricating shops?

  • Gears and variable speed which allow users to always carry out an accurate motion, regardless of the direction. 
  • Rigid but lightweight parts – this substantially machinists variable cutting speeds, each with precision cutting at every speed option.
  • Integrates height capabilities where its tip is not likely going to hang up, taking away in the process the need for human interaction.

With respect to the plasma cutting table brand you have, your plasma cutting machine’s capabilities can be determined. It is normal for plasma cutting tables to come in a 4 ft x ft cutting area. You can use here sheets of materials that have 4×8 ft or 4×10 ft dimensions. As for the machine itself, it is capable of cutting images to a maximum of 20 feet long.

In order to operate a plasma cutting table, there have to be 3 amp electrical services available. The sheer table alone would weigh around 300 pounds. Its dimensions would be 64 inches wide with a depth of 60 inches. The height would usually come by 90 inches. Accuracy-wise for this kind of material cutting tool, industry experts are asserting that it is exceptional in its own right, way better when compared to the work of a plasma torch alone.

Faithful users of Samson plasma table enjoy the use of 10ft x 5ft material sheets, which can come a little more than 1 inch in thickness. As for the cutting speed, it can reach a maximum of 1000 inches a minute. A system like this is best suited for mass production and for the benefit of large fabrication projects.

Every brand of plasma table comes with its very own dedicated application system to go with the cutting table. This computer application software is usually intended to work in complete harmony with a cutting table, to make it run.

All these components coming together as a whole unit, these systems are expected to work synergistically as one, taking your business to its next level of excellence by offering one of a kind capabilities which you can turn to the good advantage of your brand by being able to produce specialty parts.

When it comes to repetitive capabilities, Samson CNC plasma tables are second to none. One of the reasons why they are in high demand these days in the market can be attributed directly to their high precision cuts, each and every time. Opt to save the program for a future project and decide to use it at a later date.

You still have the assurance that your end product is still pretty much the same as what was previously produced. Needless to say, this state-of-the-art robotic technology and CNC concept fusing together to come up with a new milestone is no less indomitable and unbelievable.

Now, small and medium scale enterprises will have no reason to excuse themselves from increasing their level of productivity if they seriously want to, yet they can still veer away from high production costs and still minimize the production of waste materials.

The ability to optimize the use of materials by cutting out all the required elements from the exact same sheet will help a company enjoy a significant amount of savings in the end. Lowering production costs while ensuring that profits are high as possible is the way to go for good, profitable business and Samson plasma table can help you out on that.

How Does the Water Jet Cutting Process Work?

The working principle behind the water jet cutting process is very simple to understand. It takes inspiration from nature itself in how a waterfall could slowly over a long period of time cut through a hard rock below it, giving it form and shape. Water jet cutting machine manufacturers replicated this in their product offerings giving us a no less than state of the art material cutting tool like no other.

There is almost no limit to the applications of water jet cutting and the materials it can handle and cut. Since this material cutting method makes use of water jet technology, we qualify it as a highly efficient cold cutting process. The cutting power of high pressure water can be further intensified with the addition of abrasive materials, allowing it to cut an array of hard and tough materials in half the time.

Silky smooth and minimal kerfs, not to mention the non-workable cutting edges are a few of the reasons why the water jet cutting process has become the method of choice in many industries today.

waterjet cutter technology

Inspiration Behind Water Jet Cutting

As mentioned earlier, water-jet was inspired from nature, a simple functional principle. A fine, high-pressure jet of water is made to move at amazing warp speed and made to hit a particular surface of a workpiece. The action will induce material removal, allowing it to take the shape of your intended design and form.

In order to generate a jet of high pressure water, the system’s high-pressure pump will need to bring the water to certain pressure, of up to several thousand bar. Eventually, it will be directed to the cutting head.

With respect to the material that you want to cut, most especially for hard and extremely tough ones, you can combine your water with abrasive materials. As described above this measure will expedite your water jet cutting process and will cut your cutting time in half. Water will emerge from a jet nozzle opening with a diameter of 0.1 to 0.5 millimeter. The pressure of the water as well as the nozzle opening will determine the power or the intensity of the blasting capacity.

The water jet will separate the particles of the material near the surface inducing a stress-free and seamless cutting process without having to worry about the introduction of heat ingression into the material. With respect to the material’s level of thickness and the nature of the water jet, varying levels cutting depths and speeds can be achieved.

Water-Jet Cutting Advantages

  • Flexible cutting process
  • Cuts a wide range of substances and materials
  • High level of cutting precision
  • Minimal kerfs 
  • Smooth cut edges
  • No need to rework the cut edges
  • No material heat load
  • Environment-friendly method of cutting 
  • Complete absence of slag waste
  • Cutting water can be recycled

High Impacting Factors to the Quality of Cut of Water Jet Machine

There are some of the parameters that are likely to create a significant impact to waterjet cutter performance and its cutting quality. These influencing factors would include the following:

  • Nozzle opening diameter
  • Nozzle distance/proximity to the material surface
  • Pump pressure
  • Cutting head feed speed
  • Water jet machines generated cutting pressure

Learning About WiFi Antennas

Amateur radio operators used to say that if you require a bigger, more powerful signal, you need to put up some more metal components to your antenna, and have it held higher. The same can be said to be true for WiFi antennas. It is not an exception.

The strength and dependability of WiFi communications will largely depend on radio-frequency energy. They can be efficiently transmitted and they can be received as well over antennas. The use of a better quality of antenna will provide users with better coverage. Choosing the right kind of antenna should be easy and seamless, that is if you know and understand the fundamentals.

Antennas in General

Generally speaking, antennas are mechanical devices that are designed to radiate radio waves and carry out this function when you supply them with electric power. Sometimes another device can be used for this purpose, converting radio waves so they become electric power.

There are occasions that antennas are purposefully designed to work as antennas, much like the ones we have in a wireless router. We can also use them for some other purposes, those wires you see on your earbuds. They incidentally work like an antenna.

wifi antennas

We classify WiFi antennas as directional, always. This signifies that they can either receive or transmit radio waves in particular directions but may not be as efficient in other directions. Antenna systems that are not structured to work as directional are referred to as “omnidirectional” or “nondirectional”. This is regardless if we can’t qualify them as perfectly nondirectional.

WiFi Frequencies

At least 5 different bands have been reserved for the exclusive use of Wi-Fi transmissions,  3.6GHz, 5GHz, 2.4GHz, 5.9GHz, and 4.9GHz. How these bands are utilized will vary, depending upon the country where they are applied. 2.4GHz band is considered as the most widely used, even the majority of the general principles can be substantially applied to all bands.

The 2.4 GHz band can extend and this can go approximately from 2.4 GHz to 2.5 GHz. This makes the approximate center band at 2.45 GHz. This frequency is used in the calculations below.

Summing up the formula we have above:

wavelength in meters = 300 / MHz frequency

We will convert this to the following:

Wavelength in millimeters =  300 / GHz frequency

Thus, this computation above is making the 2.45 GHz wavelength signal into 122.45 mm. A 2.45 GHz dipole is 61.22 mm end to end. As for these two halves, each will be 30.61 mm. If you are most familiar working in inches, it would be 2.41” for a dipole of 2.45 GHz from end to end.

Each of those two halves is going to be 1.205”.

Regardless of the units, you want to utilize, the elements in the 2.4 GHz band are quite small. This goes even much smaller with the other 4 bands.

Antenna Polarization

Polarization refers to the orientation of the antenna with regard to the surface of the earth. The ones that are structured for their radio waves and are oriented in such a way that they are parallel to the surface of the earth are classified as “horizontal”. As for the antennas that are created for their radio waves are intentionally oriented at a right angle with respect to the surface of the earth are classified as “vertical”.

Dipole WiFi antennas can be taken advantage of either in polarization and can be done by making relevant changes to its position. The element of a dipole is parallel to the surface of the earth. For this reason, the antenna is polarized horizontally. Dipole reorientation will render its element tips to point up and down, which is what makes it polarized vertically.
