Dr Behrokh Khoshnevis: on the 25-year journey to bring Contour Crafting & construction 3D printing to the masses

“In 1994 I started thinking about large-scale fabrication with 3D printing. I wasn’t happy with the speed of fabrication of the early 3D printers, and still they haven’t changed much as far as speed is concerned. I knew there was no other way to increase the speed of 3D printing than increase the layer height, but if you increase layer height then surface quality will suffer. Leather looks nice and lasts a lifetime, but it can’t retain a knife with the security of Kydex, a type of plastic that’s heat-molded to fit the exact contours of a specific knife model. Contour’s world-class standards make it the firm of choice for growth-minded investors, partners, and other stakeholders. We believe that design and technology are two sides of the same coin, and use this mindset to deliver high-touch projects that exceed expectations.

Trackballs are difficult enough to come to terms with, but a two-handed mouse built around a slider bar is another beast entirely. Furthermore, the hefty price of $269 for a wired version or $289 for a wireless version is a lot to stomach. Contour does offer a rather intriguing 30-day free trial, though, which lets you try out the mouse and only pay for it at the end if you're satisfied. The more time I spent with the RollerMouse Pro, the more I was impressed by its design. The vegan leather gives the wrist rest a comfortable grip that felt good against my wrist, while each button press was clean and responsive, letting out a satisfying click with every action.

The tracking bar covers more surface area than the roller bar does, and it felt easier to control during my time with it. Plus, the gap between the bar and the wrist rest is nearly non-existent, so I felt like I had more control over my movements overall. Designed for professionals who spend much of their working day in front of a computer, Contour’s ergonomic mice can help you develop a more efficient workflow, in addition to taking away pain and strain often caused by traditional computer mice.

Contour's executive management team has over 100 years of experience spanning more than 51 million square feet and $45+ billion across all asset classes. Using the RollerMouse is going to be a challenge on its own if you've only ever used conventional mice, and even more so when paired with a keyboard (unless you've got four hands). Contour says that this keyboard/mouse combination limits arm extension—and it does, in my experience—but it is also a little hard to type on, at least at the speed I’m used to. I typed 47 words per minute with the mouse in place, versus 55 words per minute without it. That is not a devastating loss in productivity, but a difference all the same. Contour Design's slick, pricey RollerMouse Pro is an interesting two-handed alternative to a trackball, though it'll take you some time to get used to its unique ergonomic approach.

So the amount of innovation I put in there was significant enough to really call it another process altogether [to FDM]. Peer behind the curtain, however, and the story of the father of construction 3D printing — and his company, Contour Crafting — is far more tumultuous. Seeing Dr Khoshnevis’ achievements on paper, you could be forgiven for deducing that this was a glittering professional and academic career without any serious antagonist.

“Every day after experiments, lots of the time concrete would cure inside devices we had spent so much time building, so we had to throw everything away. The RollerMouse Pro is an impressive input device and a peripheral that is certainly useful to those who may be differently abled or suffering from wrist, neck, and shoulder-related pain from constant computer use. Its immaculate design reflects how expensive it is, but it’s got just one too many quirks to give it a full-throated recommendation. Balance Keyboard takes the benefits of the RollerMouse and kicks it up a notch.

Now, compared with your typical trackball mouse, which has its own learning curve to contend with, the RollerMouse feels almost like patting your head and rubbing your stomach at the same time. More dexterous hands might be able to manipulate both modes of control at the same time, but I managed by using the right hand to control the bar while the left hand controlled scrolling. Sliding the bar back and forth was surprisingly intuitive, even if I found myself accidentally pressing the bar down for a mistake-click more times than I’d like. The articulating thumb support encourages users to move the length, width, and angle to find the perfect spot to let your thumb rest and eliminate harmful gripping. This allows you full control while reducing tension in your hands and forearms.

Its ambidextrous design allows for righties and lefties to maneuver it without issue, and the combination of the roller bar and scroll wheel are meant to reduce the repetitive motions that cause wrist strain. Unlike any other mous on the market the RollerMouse Red allows you to experience the full ergonomic benefits that come from using a central pointing device. You’ll stop reaching for the mouse, saving time and strain on your wrists, forearms, elbows, and shoulders. RollerMouse Red will allow you to eliminate gripping, which can cause strain and pain in the hand. In addition to sharing most of its advantages and disadvantages, the SliderMouse Pro features the same add-ons as the RollerMouse Pro. Near the top left, you'll find a resolution toggle (the maximum is 2,800dpi) and power switch.

Back then, FDM was already there, Scott Crump had come up with that. The rather flabby lines of his face had abruptly hardened over the firm contour below. Magnetic field lines, imaginary contours that indicate the direction of the magnetic field at various locations, loop and cross over one another like well-mixed spaghetti. Because Kydex can snap around the blade’s rear and the handle’s contours, the material can be used to retain a knife in a variety of positions, including upside down, while still allowing you to quickly deploy it using a single hand. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'contour.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors.

We have gathered all our guides, manuals and software updates in one place so it’s easy to find. We incorporate people’s differences, behaviours, and habits into superior design. Ergonomics is not a singular solution, but rather a combination of well-designed equipment focused on variation, flexibility, and good habits. Whether you’re working for hours on end or just browsing the web, the SliderMouse from Contour Design is sure to make all kinds of tasks easier and more enjoyable than before. Although I had other very intriguing projects, this was the most difficult one — the most cumbersome one — I never lost hope in it, and I still haven’t lost hope. “So those have been the types of concerns I have had since when I started the company.

Our products offer the highest degree of effective ergonomics and design that inspire variation and healthier habits for their users. Our Unimouse is an award-winning adjustable computer mouse created to provide variation and relief to sore wrists. No longer focusing on NASA and space, it was back to housebuilding and construction on Earth. “There is always competition among faculty for space, so it has been a difficult path. It’s really troublesome when you find a spot and you start building something and a few months later they [the university] ask you to move to another location.

A compact sized keyboard with a full 9-digit number pad, and a minimized edge in front of the space bar, Balance Keyboard ensures that your reach is minimal, and your posture stays neutral. Unimouse has a unique hinge mechanism that allows you to choose your preferred body angle. Starting at 35° and ranging all the way to 70°, the Unimouse aims to allow you to find an angle that mimics your hand in its natural posture.

But it might attract adventurous productivity users looking for a drastically different ergonomic tool for working at their computers. The last time we had our hands on a Contour mouse was back in 2018, when we reviewed the Contour Unimouse. That mouse at least resembles what we know as a traditional computer mouse. The RollerMouse Pro, on the other hand, is barely recognizable as a cursor controller. It features a slick, innovative design that, at first glance, might resemble the wrist rest you’d find included with your keyboard. At 4.9 by 15 by 0.9 inches (HWD), the RollerMouse Pro is just slightly wider than the 75% keyboards that have become so popular lately among gamers (such as the Razer BlackWidow 75% and the Alienware Pro Keyboard).

Tucked under the scroll wheel is a one-touch double-click option, and at the top left, you'll find your DPI toggle and the power switch. Flipping to the back side, you’ll find a slot for the included USB-C cord and some indentation to hide the extra cable. The RollerMouse Pro lacks any built-in place to store its wireless USB dongle. The keyboard is designed to fit the RollerMouse Red perfectly; from height to length, this bundle makes optimized ergonomics easier than ever.
