There is a very real concern that plastics are harming our environments. To some, this means that anything made from the stuff is to be avoided as dangerous. Which is unfortunate. As it is with any raw material, there are pros and cons to be considered – so objectivity is key to understanding.
Since a great deal of what I make uses 3D printed plastic, I am sensitive to how potential customers perceive it. I am also aware of the role plastics play in improving our lives, as well as the damage being done by abuse of the material.
The following is a brief of how I see plastics use as it relates to what I am directly involved in – founded on 12 years of development.Continue reading “About Plastics Use in Lighted Objects”
In the process of creating lighted objects using 3D printed components, the choice of what material to employ becomes a significant consideration. Unlike novelties and hobby interests, which generally focus on cost or printer compatibility issues (material print temperatures, warping, cracking, etc.) my focus is on creating objects with high surface finish quality, extremely long life, bonding strength, overall toughness, and secondary finish capability.
Primary Materials Considered
There are three primary materials commonly used in FDM processing.
ABS or Acrylonitrile Butadiene Styrene is the most commonly used material in FDM printing of end-use parts. It is also used to produce a wide range of plastic products you encounter every day, from toothbrushes to kitchen appliances. It is tough, can tolerate some heat, and is impact resistant. It has enough flexibility to move before it breaks. ABS glues very well using solvents, making strong bonds between parts to create larger assembled components. It sands and well, and since it is a medium surface energy plastic, so wil, wet out and takes paints and adhesives well – when properly prepared. However, ABS, due to its high Butadiene rubber content, is not tolerant of UV Light exposure, which will break it down over time, making it brittle and causing it to shrink and crack around fasteners. ABS can also be a little brittle in thin wall sections, resulting in cracking around fasteners and between layers.
Unicycle Two was inspired by the first 3D print object I ever made in 2010 – Unicycle One, which was part of the 52 in 52 project. This first full object project and over 1000 subsequent projects since has been a massive learning experience. The following summarizes the progression that has taken place over these 11 years.
Not knowing the characteristics of the ABS plastic in 2010, I printed the first fixture solid, which consumed 115 cubic inches of material, at a cost of over $600. Ouch! Over the last 11 years, I have learned a lot about how to create objects with 3D printers, which is reflected in the latest iteration of the Unicycle design.Continue reading “3D Print 2010 vs. 2021 and Unicycle 2”
Names are just nouns, words, a collection of vowels and consonants in an order that allows the brain to create a pronunciation, or sound when spoken. In other words, nothing tangible. Yet, names and words are far more than that. Some, like “the” and “of” are binding words, that make sentence structure work. Others like “hot”, “fast” or “angry” impart feeling or action into a sentence. Names are words of identification.
Names establish identity to an organization, a person, or an object, that eliminates the need for additional descriptive words to create understanding and identity. Without names, how would we describe companies like Ford, Chevrolet, IBM, 3M, Apple, et al? How would we differentiate between the thousands of various products we live with every day. In many cases, the name of the originator of a product becomes the noun describing the general product category, like Coke and Kleenex, or Hoover (for those old enough).Continue reading “What’s in a Name?”
There is a lot of buzz about the idea of 3D printing taking over as the prime manufacturing method for producing products, even buildings. Some proposals include the concept of entire products being made within one machine. While the ideas are interesting and enticing, their is a long list of things that make all of this more fantasy than reality.
While the cost of 3D printed parts has been improving over the last decade, they still fall well short of the piece part prices of production tooled parts. Ignoring the cost of tooling for a moment, the cost of a stamped, die cast, or injection molded part, run in quantity, is pennies on the dollar compared to 3D printed parts.
The time that a 3D printer takes to make a part is measured in hours, compared to seconds for parts coming from tooled processes. A die cast machine, from raw material to cooled, ready to finish part might be a few minutes. Not that die cast and molding processes have a small amount of waste – as do 3D printed parts that have build trays to discard every few parts, and material that is not used from spools tails.
These two basic elements of part creation are just the beginning of the comparison lop-sidedness that ahs to be considered before running off an buying a 3D print farm.Continue reading “The Idea of a 3D Print Manufacturing Universe – Real or Fantasy?”
3D printing can be accomplished using single or multiple materials. The future of the process includes printing integrated circuits, optics, circuit pathways, heat sinks, fixture bodies and enclosures. Robotics, combined with 3D printing stations, can assemble entire products with no fasteners, no seams, and no human interaction, from a bin of raw materials.
The process involves setting up a series of 3D printers that feed into a main printer that is printing a body. At various stages, the printer is paused, and components are installed into cavities, before the printer continues. This can also include potting of cavities, as well as creating wiring vias and paths for conventional wires to pass through. The finished product would have no seams to leak, no intermediate gasketing to fail. It is an integrated assembly that used no glue or seaming of any type, making the final product durable.
This process can be repeated 24/7, with no staff present, other than to keep the material supplies loaded (also done with automation in the local area of the machine.) Customer orders can then move directly from order entry into the production que, with all available selectable options of color, optic, LED power level, CCT, control interface, etc… since the entire fixture is created from software to real world, with none of the conventional inventory of parts, components, etc… through to assembly operations.
A Simple Example to Illustrate the Process
The following is a design and process I created from raw fixture design to printed, in less than 24 hours.Continue reading “Integrated 3D Printed Handheld Task Light”
Allow me to introduce myself in a way that a resume and LinkedIn profile is unable to. I offer the following brief illustrated run down of my career in 10 Acts. Sort of a Play of evolving interests that leads me to offering you a new resource. I hope you have a moment to enjoy this adventure as much as I have. Who knows, perhaps we might one day find ourselves on a shared path.
To start, I am an artist at heart, and have been for a very long time. My first punishment in grammar school was for using my imagination to color a birds in a manner the nuns did not appreciate. This, combined with other similar incidents of expressed independence, led to my being removed from Catholic school to be placed in a conventional grammar school where my “unique” approach would not present disrupt the order of the Rigid Penguin Queens.
I come from a background of a mother who was exceptionally talented in art, and a father who was an engineer and math professor, and a multi-generational family of entrepreneurs. My father showed me the way of being a professional adult, my mother the path to artistic expression. While this duality has afforded me insight into two worlds that rarely share the same space, it has suited me particularly well in lighting – which is why I spent so many years in the industry.Continue reading “Dear Fellow Creatives”
After several decades involvement in product design and development, I’ve accumulated a few basic ideas I believe are useful for small product manufacturer businesses looking to build NPD into a driver for future growth. I pulled together 33 thoughts, updated and collected into a small book for anyone interested. Each topic is described in less than 400 words to provide the reader insight without getting too deep into the academics of each one.

A long time friend (and previous employer) decided it would be lovely to take his car apart and rebuild it from the ground up. I have witnessed my of these “projects” over the years – most end badly. Taking a car apart seems so easy. Just undo every fastener, and dump the parts that fall off into boxes – while tossing all those old rusty corroded nuts, screws, washers, broken little clips and pins into bins. When something is frozen up, beat it apart, or cut it, it’s all replaceable – right?Continue reading “Finishing the Big TR6 Project”
