All About 3D Bioprinting

3D Bioprinting


Did you know that it is now possible to print body organs using living cells? Yes, it’s happening. It’s called bioprinting and it uses a 3D printing machine. The healthcare industry is now taking advantage of 3D printing, which is a revolutionary technology that can produce almost anything. Researches and experiments in this industry are taking place and are progressing fast. Limbs, skin, and body organs can now be printed from a machine.

How it Works

Researchers and scientists use a CT scan or MRI to create 3D models or prototype for printing. These bioprinters come in many types. The first 3D bioprinter used commercially is the NovoGen MMX, made by Organovo.  It features two robotic printing heads, where one puts in the human cells while the other head places the support, which is usually a hydrogel or scaffold.

Another type of bioprinter is the six-axis printer, which uses a robot printer. Unlike traditional 3D printers that build a tissue from scratch, is capable of building multiple parts of a heart tissue and it could move the parts around accordingly. The six-axis 3D bioprinter can print layers. It is also capable of coming back and then start printing another layer on the heart’s exterior. Valves have their own spot, and then a robot could take the valves in and place them in the parts of the heart.

Some 3D bioprinters are inkjet-inspired that can use multiple types of cells and components for printing. Earlier forms of 3D bioprinters place human cells in actual ink cartridges. With a customized program, the printers would then place the cells together in a certain order. Today, it is possible to print skin cells directly on a wound by placing the cells in an ink cartridge.

Cells as “ink”

Once the company chooses a tissue design it will then make the “bio-ink” from the cells. The cells are layered until the tissue is complete. In between are water-based layers, which is hydrogel. The hydrogel can also fill in tiny spaces in the tissue. It also used as support to the printed tissue. Another material that is used to put cells together is collagen. This layer-by-layer process is the same as the tradition 3D printing approach. While traditional 3D printers produce products from the ground up, bioprinters use hydrogel or collagen to fuse cells together, creating a tissue.

Stem cells in bioprinting

Another option for bioprinting bones and different organs is using stem cells, as these cells can easily grow into tissues. Researchers and scientists have been experimenting in making bone replacements that are covered with stem cells. Overtime, these stem cells will develop into tissues. Development of stem cell repair is also another focus of the medical field, which is used for complex tissues such as the tissues that make up the liver, the heart, and other vital organs. Using stem cells in building vital body organs may be difficult, but with 3D bioprinting, it may be possible.

Use of Vacuum Packaging Machines

Not everyone may know and be interested in a vacuum packaging machine, but this equipment has made a huge impact on the packaging industry. It has also made a difference in everyone’s life, one way or another. In fact, it has become a popular smart kitchen accessory over the years.

Other terms used to refer to this machine are the chamber vacuum packer and the external vacuum packer or external bag machine. The external bag machine is ideal for home use, while the chamber vacuum machine, which is big and heavy, is commonly used in commercial settings.

 

Vacuum Packaging Machines for Home Use

A vacuum packaging machine helps reduce waste, allowing food to last longer. If you want to get your own external bag machine, you need to decide on your budget. If you buy cheap ones, you will get what you pay for. Choose the machine that works well and will keep working well for a long time. Check out also the warranty provided for the machine you will purchase.

This home use vacuum packer has an open port the vacuum bag is attached. When you switch the machine on, the air is emptied. With some external bag machines, the heat sealing of the bag is done at the same time. While with other vacuum packers, sealing of the bag is done separately.

 

Vacuum Packaging Machines for Business

In the past, only the major fruit and vegetable exporters have the access to vacuum packaging machines. However, because of the recession, prices of these machines fell dramatically, making them far more accessible and affordable to smaller businesses. The problem, however, with these businesses is that they are not used to maintain and keep these machines. Keep in mind that if these machines are not maintained to a good standard, they are most likely to go wrong and you will be spending on repairs. The main areas to monitor include the seals and the heating strip.

 

The Seals

The entire process of vacuum packaging greatly depends upon the quality of the seals used. Otherwise, it will not be good to use anymore. When the bag is fastened to the machine, the entire area around it must be sealed to create a vacuum.  Then, all the air is sucked out, which is why it is called vacuum. Eventually, after many uses, the seals have a tendency to wear out and lose its ability to create a seal.

 

Heating Strip

The heating strip is another important part of the machine. You’ll often find the strip covered with Teflon. This covering prevents the strip from sticking to the bag. The Teflon can last for several years, depending on the usage and maintenance, but a qualified technician can easily replace it if the need arises. You will know that it is time to replace it when the strip starts to stick to the bags.

Insulated Concrete Forms for Sale: What You Need to Know

The reason why we see a lot of insulated concrete forms for sale today is because of the fact that is preferred by many people due to a number of reasons. Some of its benefits would include being tough, long lifespan, and energy-efficient that only needs very minimal upkeep.

What is ICF?

It is a pre-made foam that fits together like interlocking blocks. The outside is are flat sheets of foam insulation. The sheets are connected with the use of a plastic framework. During the time of construction, the blocks are fitted together, then laced with rebar, and filled with concrete. The forms are then insulated both outside and inside, this providing a high level of wall insulation that is not common in standard home constructions. Due to the fact that the blocks fit together, there is very little air infiltration which then increases the insulation value.

Insulated concrete forms for sale are used to build houses that are consisted of two layers that are approximately two inches thick, both inside and out.

The rigid insulation has a 6-inch thick layer of concrete. It measures almost 16 inches by 4 feet long by 12 inches wide. They also have an inner and outer framework made of plastic which helps stabilize the form and provide strips that could be drilled to the mount drywall, wood trim, cabinets, and siding on the outside.

Moreover, ICF is also used for underground homes, multi-story homes, and basements. They begin at the foundation and go all the way to the roofline. There are some builders that only make use of ICF forms and combine them with other building methods.

 

Energy Efficiency

Among the primary reasons why people choose ICF construction is because of energy efficiency. Since the walls are uniformly insulated with solid sheets of foam, there are no channels for air to get through. In an ICF wall, there is no hot and cold spot. In stick-built construction, the r-value is diminished by air infiltration and heat transfers on the wooden studs, around the outlets, and other wall penetrations where fiberglass insulation does not fill the area.

 

Durability

One more reason why people choose ICF construction is its durability. It is capable of withstanding different weather conditions. If the home is built with ICF, you can rest assured that it will not be easily destroyed.

 

Cost

ICF homes cost almost 6% more compared to stick-built. Part of such is material cost and part of the cost is added labor that is involved in working with other aspects of ICF. This may vary as the cost of materials could fluctuate. There are some manufacturers of ICF that offer discounts on forms to those who are in the process of rebuilding homes that were destroyed by storms.

 

Construction

As mentioned, these concrete forms are laced with rebar, assembled, Lego-styled, and filled with concrete. Due to the fact that rebar and concrete provide strength to the wall, temporary framing is being used during the pour.

Many homes today make use of ICF because through the years, they have seen how beneficial it is to use one. If you are in the process of building your home, then this can be one of the best options you can consider.

Electronics Design in Melbourne: Common Mistakes to Avoid

The majority of executives are responsible for managing the performance of the product or warranty returns. They are also the ones who can tell that the most common cause of headaches in manufacturing often comes from manufacturers and suppliers. Reliability in electronics design in Melbourne is very important as it can make or break the product. Design has an integral role to play in the product’s manufacturability. The easier it is to manufacture, the better will be its tolerance to standard variations in manufacturing processes.

Moreover, it has a role to play in component reliability as those designs that avoid the use of extended value components, lessens the application of electrical and thermal stresses can help reduce the risk that marginal components would induce product failure.

 

Flex cracking

This mistake usually occurs when the printer circuit board (PCB) under a ceramic-chip capacitor extremely bends. This capacitor is not capable of responding to cracks and strains. Flex events could happen during testing, depaneling, card insertion, attachment or from accidental dropping or mechanical shock. The approach to this will depend on the design constraints, cost constraints, as well as the degree of acceptable risk.

 

Custom Connections and Joint Wear

Some extensive design for reliability efforts are highly focused on avoiding wear out. One of the best approaches to this is to assess robustness in the design phase by deriving predictions based on the first and second order models.

Designers of PCB only think in two dimensions. But in some applications, heat sources that separate from electronics could be hot or close enough to cause a serious temperature rise. A designer might forget about such heat sources during modeling and might not install them during testing only to find out that they can actually cause solder joints to wear out.

 

Electrolytic Capacitors

Most designers like an electrolytic capacitor for its high capacitance. On the other hand, they may hate it as they tend to fail over time. Such love and hate relationship have led to a wide range of methods for predicting and derating lifetime. So, what will be the best approach to this? This will be dependent on whether you plan on derating voltage, temperature, or ripple current. Given this, you have to keep in mind that an electrolytic capacitor will work best when voltage is applied to it. Without voltage, it will have no capacitance and dielectric.

Designing for the purpose of reliability can be a bit of a challenge. It plays an important role in great success of a product as well as the company’s bottom line. It is important that you assess the evolving design, solve problems before they become worse, and find potential weaknesses. Addressing and recognizing possible problems would prevent the serious issues along the way. With this, you will be worry-free so you can better sleep at night.

Waterjet Machine: Keep it Running with Proper Maintenance

The high-pressure coming from a waterjet machine allows the cutting of a very wide range of materials using cold water or mixing water with abrasive for hard materials. The power and accuracy of the machine allows high-precision cutting even for shapes that can be complicated to cut.

To make sure that all these are achieved, proper maintenance should be done in the machine so it can get the job done while meeting the expected results.

 

Running the Equipment

The more the equipment runs, the more chances for things to break. Running it at a high pressure will need more maintenance.

 

Taking Care while Doing the Maintenance

If you rebuild your waterjet machine in a clean room, it can last longer than rebuilding it in a dirty environment. There are many high-precision components in the machine that have microscopic bits of grit that could get damaged easily. Just a bit of dust getting into the jewel in the nozzle could cause the machine to shoot to the side and cause the wear of the mixing tube. Make sure to take the parts to a clean area with a sink so you can wash them before reassembly.

As soon as you get your machine, expect to be overwhelmed during the first days of training. As soon as you have completed the training, you will be confident knowing that you can operate it and getting an idea of how to properly maintain it. But it will be after a few weeks before you can do your first maintenance.

 

Frequency of Maintenance

Water jet cutters definitely needs maintenance. For example, you should change the nozzle parts on a regular basis. For the pump parts, they are changed less frequently. Make sure that you keep the critical aspects at hand so you will not stop machining while waiting for the spare parts to arrive.

Generally, the maintenance will depend on how much pressure you run, as well as the frequency of the on and off cycles of the machine. At the same time, if there hard or dirty water, you may have to perform maintenance more often. It may also require you to invest in a filtration system or to purchase a water softener.

 

Ease of Maintenance

In most cases, anybody who is capable of changing the brake pads of a car can keep an abrasive jet machine going, given a good manual and training, as well as some occasional call to a tech support guy. Mixing tubes could get wear but they can be easy to replace. But pumps would require occasional seal changes. Depending on the design of your pump, the seal could anywhere from quick and easy to time-consuming and difficult to replace.

Any machine, without proper maintenance is bound to fail eventually. So, if you want to make the most out of your machine’s performance, make sure that you know how to maintain it properly.
