Predicting The Future: How’s That Working Out?

February 14, 2022 by 73 Comments

With 2022 off to a good start, it is about time to let go of all those New Year’s resolutions that didn’t quite work out. The scale’s needle didn’t reverse, our nails are still bitten, and we are still binge-watching Breaking Bad instead of reading the classics. But, of course, there’s always the future where we just know we’re going to stick to our resolutions. Besides, the future will be replete with fat-eating nanobots, 3D printed nails every morning, and a pill you can take that will make you remember reading Ulysses.

Predicting the future is fraught with peril, which is why launching a new company or product is so risky. However, there have been a few prognosticators that have made some impressive forecasts. For example, in 1922 popular (if not critically acclaimed) author W. L. George wrote a piece for The New York Herald titled “What the World Will be Like In a Hundred Years.” Since May will see that piece’s 100th anniversary, let’s see how he did.

What We Are Doing Wrong. The Robot That’s Not In Our Pocket

October 11, 2016 by 109 Comments

I’m not saying that the magic pocket oracle we all carry around isn’t great, but I think there is a philosophical disconnect between what it is and what it could be for us. Right now our technology is still trying to improve every tool except the one we use the most, our brain.

At first this seems like a preposterous claim. Doesn’t Google Maps let me navigate in completely foreign locations with ease? Doesn’t Evernote let me off-load complicated knowledge into a magic box somewhere and recall it with photo precision whenever I need to? Well, yes, they do, but they do it wrong. What about ordering food apps? Siri? What about all of these. Don’t they dramatically extend my ability? They do, but they do it inefficiently, and they will always do it inefficiently unless there is a philosophical change in how we design our tools.

RetroFab: Machine Designed Control Of All The Things

May 14, 2016 by 10 Comments

On the Starship Enterprise, an engineer can simply tell the computer what he’d like it to do, and it will do the design work. Moments later, the replicator pops out the needed part (we assume to atomic precision). The work [Raf Ramakers] is doing seems like the Model T ford of that technology. Funded by Autodesk, and as part of his work as a PhD Researcher of Human Computer Interaction at Hasselt University it is the way of the future.

The technology is really cool. Let’s say we wanted to control a toaster from our phone. The first step is to take a 3D scan of the object. After that the user tells the computer which areas of the toaster are inputs and what kind of input they are. The user does this by painting a color on the area of the rendering, we think this technique is intuitive and has lots of applications.

The computer then looks in its library of pre-engineered modules for ones that will fit the applications. It automagically generates a casing for the modules, and fits it to the scanned surface of the toaster. It is then up to the user to follow the generated assembly instructions.

Once the case and modules are installed, the work is done! The toaster can now be controlled from an app. It’s as easy as that. It’s this kind of technology that will really bring technologies like 3D printing to mass use. It’s one thing to have a machine that can produce most geometries for practically no cost. It’s another thing to have the skills to generate those geometries. Video of it in action after the break.  Continue reading “RetroFab: Machine Designed Control Of All The Things” →

A Look Into The Future Of Slicing

April 7, 2016 by 48 Comments

I’ve had a few conversations over the years with people about the future of 3D printing. One of the topics that arises frequently is the slicer, the software that turns a 3D model into paths for a 3D printer. I thought it would be a good idea to visualize what slicing, and by extension 3D printing, could be. I’ve always been a proponent of just building something, but sometimes it’s very easy to keep polishing the solution we have now rather than looking for and imagining the solutions that could be. Many of the things I’ll mention have been worked on or solved in one context or another, but not blended into a cohesive package.

I believe that fused deposition modelling (FDM), which is the cheapest and most common technology, can produce parts superior to other production techniques if treated properly. It should be possible to produce parts that handle forces in unique ways such  that machining, molding, sintering, and other commonly implemented methods will have a hard time competing with in many applications.

Re-envisioning the slicer is no small task, so I’m going to tackle it in three articles. Part One, here, will cover the improvements yet to be had with the 2D and layer height model of slicing. It is the first and most accessible avenue for improvement in slicing technologies. It will require new software to be written but does not dramatically affect the current construction of 3D printers today. It should translate to every printer currently operating without even a firmware change.

Part Two will involve making mechanical changes to the printer: multiple materials, temperatures, and nozzle sizes at least. The slicer will need to work with the printer’s new capabilities to take full advantage of them.

Finally, in Part Three, we’ll consider adding more axes. A five axis 3D printer with advanced software, differing nozzle geometries, and multi material capabilities will be able to produce parts of significantly reduced weight while incorporating internal features exceeding our current composites in many ways. Five axis paths begin to allow for weaving techniques and advanced “grain” in the layers put down by the 3D printer.

Hyperloops And Robot Cars, A Glimpse Into The Future

April 6, 2016 by 40 Comments

His mobile blooped at him with one of those noises a company spent money to get. A timer started on the screen as he rushed to put his shoes on. He finished and pushed open his door, running down the stairs two to a bound. By the time he reached the bottom of the stairs he had his backpack slung over both shoulders, which he mentally cursed himself for since he’d just have to take the dang thing off again.

It was morning on January first, and he was due at his parent’s house for a new year’s dinner fifteen hundred miles away. He should have booked a plane weeks ago, but now the Loop was his only option. The Loop didn’t really have peak rates, and while the plane would be a little faster, more direct, and cheaper IF he had remembered to book it in time, the Loop would take him the same distance today. Plus, the seats were comfier. They reclined nicely, and he intended to nap on the way. Hopefully, by the time he got there, the bleariness from last night’s celebration would be undetectable by parental senses.

He locked the door to his apartment complex, a reassuringly square assembly from the seventies, and walked to the sidewalk where a friendly light blue car waited for him. When he got close, his mobile vibrated and made another distressingly cheery noise. The doors of the car swung open opposite of each other to expose the space inside. The car displayed two rows of inward facing bench seats, a panoramic row of windows around the entire perimeter of the vehicle, and… yes, his nose was telling him before his eyes fixed on it, a very unsettling amount of vomit in the center of the floor.

He turned around, a bit squeamish, and took out his mobile. He navigated through the controls. Where is the menu option? What year is it now? Why is this still hard? Three awkward menus deep and he finally found and selected the option to let the dispatch know the car had an issue which made it uninhabitable. The car immediately began to chirp warnings and the doors soon started to close. In a moment, a human somewhere in the city would be looking at a video of the inside of the car, determining him a liar or not. As expected, a few seconds later, the little car began to drive off. The lights on the rear of the car turned from bright red to the yellow amber of headlights as it decided its front would be its back. It drove off to the dispatch center for cleaning and repair. Someone would be eating a 100 dollar cleaning bill today. He didn’t feel sorry for them.

His phone began to vibrate. He picked it up to answer a call from a bored customer service representative who was trying hard to sound earnest. “Sorry for the trouble sir, the ride today will be free. We have another car on its way”
