3D Printing – Fad or Practical Tool?

For a while, it seemed as if 3D printing would take the world by storm and that we’d all have 3D printers in our homes pumping out anything we needed. However, since my last article on the topic, 3D Printing Done Faster and Better, the number of articles about 3D technology have decreased noticeably. In fact, the trade press has been a lot quieter on the topic, which makes some people wonder whether 3D printing is actually a fad. The problem with much of the new technology that becomes available is that people initially think there are all sorts of uses for it, but then discover that those uses aren’t practical or that they’re too expensive, and they end up dropping the technology (rather than revise their vision).

You can still find some fanciful uses for 3D printers. For example, the Washington Post recently ran an article recently ran an article on how 3D printers can change the presentation of food. The idea is that you really can have the food presented in a manner that is both pleasing and unique. The idea is to make food in unusual shapes, sizes, and colors, so that it appeals to a larger group of people. However, the original vision was to combine ingredients to actually make the food—this application scales the idea down to a more practical level.

It also looks like 3D printing will see practical use for various higher end needs that aren’t quite professional, but are out of reach of the home owner. Think of printers like the da Vinci 1.0 Pro 3D as a middle ground for experimenters (see the ComputerWorld review). The price is out of reach for the general consumer, but definitely within the range for experimenters and early adapters. Again, the vision is scaled down, more practical, and infinitely more usable.

The military is also using 3D printers to perform practical tasks. Having been a sailor myself, I can tell you without reservation that I would have loved to have been able to print some of the items I needed. Waiting to get back to port before I could even order parts meant serious delays and downed equipment. Imagine having the ability to print a new drone or other needed items while out to sea, rather than waiting for a supply ship or in port visit.

Of course, the medical and other high end uses for 3D printing continue to evolve. For example, 3D printed hands are becoming ever more usable. Expect to see all sorts of new medical uses for 3D printing evolve because humans are notoriously difficult to fit. I envision a day when it becomes possible to print just about any body part needed in the right size, color, shape, and characteristics. New printing strategies may even make the use of organ replacement drugs a thing of the past.

The point is that 3D printing is expanding, growing better, becoming more practical, and still evolving. Yes, you might eventually have one in your own, but don’t expect it to happen anytime soon. Practical uses for 3D printing are becoming more common. Until 3D printing becomes a must have technology for industry, science, military, medical, and other industries, the price won’t come down enough for the home user. To answer my initial question, 3D printing is becoming more practical tool than an interesting new technology, which is why you hear a lot less about it today.

Cutting Up a Chicken

When you raise your own chickens, you eventually end up with a lot of whole chickens in your freezer and will need to cut at least a few of them up for use. Most people are used to seeing chickens already cut up for use in the store. If you do get a whole chicken, it’s usually with the idea that you’re going to roast it whole. In many cases, people don’t know where to begin cutting a chicken up for use because the butcher has done it for them for so many years. Following the chickens you find in the store as an example won’t work very well either because they’re cut up using a meat saw (think of a band saw specifically designed for cutting meat). Unless you also have a meat saw, you probably won’t be able to follow the butcher’s example. This post describes how to cut up a chicken using nothing more than a standard utility knife.

I recommend using a 6-inch knife with a fairly stiff blade. A boning knife will be too flexible and something small, such as a pairing knife, won’t give you enough leverage. Don’t use a knife with a serrated edge—the serrations will make for a poor cut and you won’t be able to split the breastbone with such a knife. The knife you use should be sharpthe sharper the better. A dull knife is dangerous to use.

Start with the wings. Your cut should begin behind the joint area. When you lift the wing up, you’ll actually see a bit of the flesh come up with it. Start your cut immediately behind this fleshy area and angle toward the joint as shown here.

CuttingChicken01

Cutting the wings in this way has the advantage of making them a bit meatier. After you cut off both wings, it’s time to cut off the combination of the leg and thigh. Start by lifting the thigh and cutting toward the joint from the front of the chicken as shown here.

CuttingChicken02

Once you get to the joint from the front, you’ll need to cut to the joint from the back as well. When this cut is finished, you’ll be able to rotate the leg/thigh combination downward and see the joint pop from the socket as shown here.

CuttingChicken03

You can finish the cut at this point. Remove both leg/thigh combinations using the same approach. Now you can separate the leg from the thigh. There is a natural division between the leg and the thigh. If you look carefully, you can actually see where the two separate because the meat goes in two directions. Look carefully at the following picture and you’ll see that the line shows this separation.

CuttingChicken04

Cut straight down through this point and you’ll find, with practice, that the knife will neatly separate the meat at the joint. At this point, you’ve cut off the wings, legs, and thighs. It’s time to remove the lower back (the part with the tail).

Look inside your chicken. You’ll see that there is a fleshy part between the rib cage and the lower back. The fleshy part extends on both sides of the chicken. You’ll cut through this fleshy part to separate the lower back starting midway at the opening as shown here.

CuttingChicken05

Cut through the fleshy part. You should then be able to flex the lower back and see the backbone separate from the rib cage as shown here.

CuttingChicken06

You can then cut through the spinal cord to separate the lower back from the rib cage. Cut straight down.

The hardest cut to make is to separate the two breast halves. However, like many things in life, there is a trick to it. Look at the center of the breastbone and you’ll see a line runs through it. Now, look at the first complete rib and trace it around to where it meets with the breastbone. You’ll see a second line of a sort that forms a cross as shown here.

CuttingChicken071

Put the tip of the knife through this point and you’ll find that the breastbone cracks easily. Now, draw the knife down much as you would with a paper cutter. You’ll find that the knife easily slices through the majority of the breastbone and the cartridge as shown here.

CuttingChicken08

After you make this cut, move your knife higher up. Don’t put it through the hole where the neck is, but do place it higher into the cavity. Use the point to finish breaking the breastbone apart. At this point, you should also be able to break the wishbone in half. Now you can separate the two halves of the breast like this because there is cartilage separating the breast from the upper back.

CuttingChicken09

Cut the cartilage holding the upper back to the breast halves. You’ll reach another joint after you cut the ribs. Separate the joint and the cut through it as shown here.

CuttingChicken10

You should now have ten pieces of chicken as shown here:

CuttingChicken11

These pieces are: left and right wing, left and right leg, left and right thigh, lower back, upper back, and left and right breast. Although this combination doesn’t look quite like the chicken you get in the store, it’s the most effective means of cutting a chicken up using just a utility knife. In addition, using this approach makes more of the pieces a usable size. Let me know if you have any questions at John@JohnMuellerBooks.com.
