3D Printing Practical Applications: The Peg

3D Printing Practical Applications: The Peg

Today’s blog post is brought to you by the one and only Robert Nipper, a practical 3D applications guru who has also taught us how to repair a broken Crock Pot and build a basic holiday ornament. No Need to Run to the Store – 3D Printing Practical Applications. As I was on my way out the door this morning, my darling wife shared some information with me: “The shelf in the white hutch fell down. “ The white hutch is a catch-all piece of furniture that resides in the breakfast nook, housing everything from craft supplies to cookbooks to small hand tools and greeting cards. Imagine a junk drawer on steroids. I went to investigate with her. The shelf had fallen last night, and she had already done her best to triage the situation. I asked where the shelf was now. “Right there” she said. I then asked about the pegs that the shelf was resting on. She handed me two small white plastic pegs. Two. Just two. “There are supposed to be four of these” I commented. She informed me that there were only two, and asked if I could have it fixed before our neighbors came over for dinner. Since Christmas was just a couple of weeks away, we both had a full schedule. I didn’t really have time to go across town and look for replacement supports from the home supply store. Then a smile crept across my face. I am not sure she knew what I was thinking, but she was very familiar indeed with what I had to say next: “I can 3D...

3D Printing Basics: Printer Build Volumes and Tolerances

How big do you want to print? Last week in our 3D printing basics series we discussed the history of 3D printing. Today, we are going to explore the wide variety of printer build volumes and tolerances that allow you to create prints ranging from very tiny to quite massive. While all printers work by building a part layer by layer, the machines can vary significantly in terms of quality and functionality. When searching for a 3D printer for your home or office, you can really distinguish one printer from another based upon the printer build volumes and tolerances. Printer Build Volumes The build volume, quite simply, determines how big your machine allows you to print. For years, analysts believed that limited build volumes were the biggest obstacle standing in the way of widespread adoption of 3D printing technology. Today, we are starting to see the design of 3D printers re-imagined in ways that allow them to build full-scale structures, effectively eliminating this critique. Starting at the true desktop level, the printer build volumes for a 3D printer can be quite limited. Many of the entry level printers, especially those around or below the $1,000 mark, have rather small build volumes, mostly less than four inches by four inches by four inches. This means that you can only print something that would fit inside of a four inch cube. While this is enough space to play around with the technology and build little trinkets, if you want to make actual, usable parts, you will find a four-inch limitation to be rather cumbersome. Moving into the next level of printers,...

3D Printing Basics: The History of 3D Printing

The History of 3D Printing Do you think of 3D printing as a brand new, cutting edge technology? Well, you are half right. While it is true that 3D printing is cutting edge and has only entered the mainstream in recent years, the history of 3D printing actually dates back more than three decades. In fact, the first recorded design for rapid prototyping (RP), the technology that 3D printing is built upon, was developed by a Japanese lawyer, Dr. Hideo Kodama, in 1980. Rapid prototyping is simply any technique that uses computer aided design (CAD) programs to quickly develop a 3D model. The term rapid prototyping is often used interchangeably with additive manufacturing. Unlike traditional prototyping techniques that could take many weeks to complete, rapid prototyping technologies allow businesses to receive their prototype within hours of creating the design. The Breakthrough and the Rise of 3D Systems The first big breakthrough in 3D printing took place in 1983 when Charles “Chuck” Hull invented the first stereolithography apparatus. Hull would go on to found 3D Systems, one of the highest grossing 3D printing companies in operation and a company that we are proud to be a re-seller for. Hull came up with the idea for his machine while he was working on lamps for UV-curable resins and realized that the process could be used to create bonds in the resin that would build objects layer by layer. Remarkably, the first inkjet printer had just been invented in 1976. There was only a period of eight years separating the invention of the first machine capable of printing in 2D and the...
