An Exciting and Promising Technology

3D printing is an exciting technology that is rapidly increasing in popularity and affordability. A few years ago, 3D printers cost many thousands of dollars. While devices with advanced capabilities are still expensive, consumer-oriented printers are now affordable for many people. These devices can create a wide variety of useful, artistic, and fun objects.

The most exciting aspect of a home 3D printer is that it's so versatile. Some examples from the huge range of items that can be printed include cups, vases, cookie cutters, napkin rings, bracelets, pendants, rings, ornaments, tools, and even items of clothing. Artists can create sculptures and parents—or children—can create toys. Special 3D printers can create edible items and are available in consumer versions as well as professional ones.

A model of the object to be printed must be created in a 3D art program. Information from the model is then sent to the printer. People can create their own unique object designs or they can download designs from websites. Some companies print the objects for people. Some of these companies also let people create their own online store to sell objects that they've designed.

Pens that create 3D objects are available for purchase and cost considerably less than a printer. People are finding creative uses for the pens. They are an interesting device for creating three dimensional art and sculpture, although the resulting objects don't look like those created by a printer.

An Introduction to 3D Printing

3D printing is becoming very useful and important in medicine and manufacturing. This article looks at facts about the technology that are relevant to consumers.

How Do 3D Printers Work?

The first step in the creation of a 3D printed object is to design the object. This is done in a 3D art, CAD (Computer Aided Design), or animation program. The computer model is then exported as an STL file. A second program, known as a slicing program, reads the STL file and converts it to G code. This code tells the printer to produce the object in a series of horizontal layers. The printer then prints these layers one at a time, starting with the bottom layer.

Most 3D printers aimed at consumers are plastic extrusion or FDM (Fused Deposition Modeling) printers. High-end FDM printers are available, but the less expensive ones are most likely to be purchased by consumers. The printers create objects by melting plastic filament and then extruding the hot liquid on to a platform. The plastic solidifies almost immediately after it's released from the extrusion nozzle of the printer on to the build platform. The nozzle moves in different directions to create the object and the platform moves downwards as the object grows in depth. Each new layer of plastic that is extruded fuses with the one below. This process is sometimes known as additive manufacturing.

Printers for Consumers

Consumer-oriented FDM printers are dropping in price and are becoming more affordable. It's no longer necessary to spend thousands of dollars to buy a 3D printer for the home. In fact, there are a number of printers that cost under US $1000. Some models cost only a few hundred dollars. The cheaper models usually print smaller objects than the bigger ones, however.

In addition to the price, another thing to consider when buying a 3D printer is its ability to create thin layers. The thinner the layers, the less obvious they are in the printout and the smoother the appearance and feel of the object. The thinness of the layers is known as the resolution of the printer. Generally, the higher the resolution, the more expensive the printer.

Some people who work with 3D printers predict that within a few years FDM printers will become the equivalent of today's inkjet printers—popular, inexpensive and able to produce items of good to very good quality.

Some 3D printers are now in the price range of popular desktop printers that print with ink. If you're tempted to buy one of these 3D printers, identify the features that you give up in exchange for the relatively low price. In addition, consider the ongoing cost of plastic media purchase.

Filaments That Mimic Natural Materials

Creating or Downloading Models

Free 3D modeling programs are available for the different computer operating systems. Many of these programs can create STL files. Free G code creation programs are also available. It's not necessary for someone to create their own models, however, unless they enjoy the process and want to create unique designs. A wide variety of models can be downloaded from the Internet.

One site with a large number of downloadable models is Thingiverse. The models are free and the community is active. It's a fun site to explore. The file format and the license of a model should be checked carefully before it's downloaded. The license may allow an object to be created for personal use but not for commercial use.

Print-On-Demand Websites

Several online companies print 3D objects for consumers who don't have a printer. Some of these companies also allow people to set up an online store to sell products that they've designed.

Shapeways is a popular website for people looking for a 3D printing solution. Objects can be printed in different media, including plastic, metal, food-safe ceramics, and sandstone. The printouts have a better quality than objects printed from a consumer-oriented printer. People can upload their designs and sell products based on the designs via the company's website. Shapeways is located in New York but ships to most countries around the world.

Sculpteo is another online company that prints objects for people and also lets them run a store. Sculpteo is based in France, but like Shapeways it ships around the world.

Some 3D printers have a sleek and modern design. The mechanism is hidden, as in a microwave oven. In other printers, as in the one above, the parts are clearly visible and there is no attempt to make the printer attractive.

Drawing With a 3D Pen

For some people, even the cheapest 3D printer is too expensive. Comparatively inexpensive products known as 3D pens might enable more people to create three dimensional objects and have fun at the same time.

Multiple companies make the pens. The basic idea behind most of them is to plug the device into an electrical outlet or a USB port and then feed plastic filament into the opening at the end. The pen heats the filament and extrudes the soft material from its "nib". The pens enable people to draw with extruded plastic on a flat surface or in the air. Both one dimensional objects with a raised surface and true 3D objects can be created.

At least some of the manufacturers provide free stencils that can be downloaded. A person can draw over the stencil with the pen. The tracing can then be moved into an upright position. Different tracings can be attached to each other with the pen in order to create a complex object.

3Doodler Pen Versions One and Two

The 3Doodler was the first 3D pen created (as far as I know), but it now has multiple competitors. The video above shows some of the objects that it can create.

Plastic in the Environment

As much as I love to read about the exciting advances in 3D printing technology, one thing worries me. All of the consumer-oriented printers that I've seen have used ABS plastic as a printing medium. ABS plastic, or acrylonitrile butadiene styrene, is a tough, impact-resistant material that has many useful applications. Like most plastics, it degrades when it's exposed to ultraviolet light. This is a very slow process, however.

Plastic pollution is a serious environmental problem. The thought of people discarding unsatisfactory 3D printouts is scary, especially as 3D printing becomes more popular. Consumers need to be encouraged to recycle their plastic or to use a more environmentally friendly material for printing. Objects made from ABS plastic can be heated and extruded into filament to be used again. Some companies sell devices that can do this to consumers.

ABS or PLA Plastic

The 3Doodler and some 3D printers can use either ABS plastic or PLA plastic as their "ink". ABS plastic is made from petroleum. PLA (polyactic acid) plastic is made from corn or soy beans and is biodegradable. Some people choose PLA filament for their printer for this reason. However, being biodegradable doesn't mean that PLA plastic can be thrown into a landfill and left for microbes such as bacteria and fungi to break down, as the term implies. The microbial decomposition of PLA requires exposure to a high temperature, light, and oxygen for two or three months, conditions which are only found in a commercial compost centre.

ABS plastic has better properties than PLA plastic with respect to the creation of 3D models. It's less brittle, more bendable, less sticky, and less susceptible to drooping when the temperature rises. The 3Doodler maker recommends that people start with ABS plastic and then try PLA plastic later.

Printed Zombies and False Teeth at CES 2019

New resins for 3D printing are appearing. One with a texture resembling rubber was demonstrated at CES (the Consumer Electronics Show) in 2019. Items printed with the resin can be compressed and then return to their original shape once the pressure is removed.

The Future of 3D Printing

Some people predict that a 3D printing revolution will take place in the near future. The printers are rapidly gaining acceptance in manufacturing and have exciting applications in medicine. In the future, people may make more of the products that they need at home instead of buying them in a store. Consumer printer technology seems to be advancing more slowly than manufacturing and medical printer technology, however.

Some Requirements for Success

The current state of 3D printing is certainly interesting and provides great scope for creativity. In order to become a more mainstream technology, though, 3D printing technology needs to be improved. 3D printers for consumers need to have at least some of the following features in order to be successful. They should be able to:

  • create useful items more conveniently or more cheaply than the same item made by other methods
  • create high-quality objects
  • make improved versions of objects manufactured by other methods
  • make objects that couldn't be created in any other way

3D printers aimed at consumers should also be easy to use and relatively inexpensive to buy and operate. The problem of finding strong but environmentally safe printing media also needs to be solved. I'm optimistic about the future of 3D printing, though. The technology is very promising as well as exciting.

      This is the most in-depth article that I have found on 3-D printing, well done, Alicia. I have been following the technology for quite some time.

      With all my research the one thing I've been lacking was an understanding of the methods used for creating the digital files, known as the STL files. You explained all this very well in this article. And now I feel I have a much better knowledge.

      It's going to be an amazing future without limitations for creative people who design products but who don't have the funds for expensive 3-D printers. As you explained, people can create an online store to sell products printed by fulfillment companies such as Shapeways.

      Nice to know about downloadable models for 3d at Thingiverse. This topic gets me so excited; almost as much as regenerative medicine. We live in a truly remarkable time. It would be nice to be able to compete in manufacturing with low wage countries when the price of these printers comes down - after all, we could all become cottage manufacturers - but I fear the countries over there will simply order printers, take them apart, and copy them. After all, what is to stop them?

      I found your article on 3D Printers very insightful and interesting! It's amazing how technology is so expensive when it first comes out and then drastically drops in price as technology evolves. That's the thing with technology it changes every day. I have been to CES in Las Vegas on several occasions with my husband and it's incredible seeing all the latest gizmos and gadgets with exorbitant price tags. I always think it's best to wait so that all the kinks get ironed out of new products and hopefully the price comes down as well. Great article! Thanks for sharing.

      My pals and I in the promotional products industry are watching these 3D printing developments with great interest. Why print up hundreds of mugs when you can "print" up just what you need?

      I totally agree that the plastics will need to become eco friendly. People, especially on the consumer level, are more apt to pitch bad "copies" and no longer needed items into the trash, thereby increasing our landfill issues.

      Great and timely hub!
