3DReactions was founded by John Majersky and Dana Majersky under JODA Enterprises LLC. From the beginning, the company was driven by John’s passion for emerging technology and hands-on manufacturing, with an early focus on exploring what was possible with 3D printing and advanced imaging.
In its early years, 3DReactions worked extensively with 3D printing, rapid prototyping, and 3D scanning. This included developing custom camera arrays and photogrammetry systems capable of capturing people and objects in extreme detail. That work required precision, repeatability, and a deep understanding of how images are captured, processed, and translated into physical output—skills that continue to shape how we operate today.
As the business evolved, 3DReactions shifted its focus to custom flip lenticular printing, where technical accuracy and visual impact come together. Flip lenticulars allow a single image to transition cleanly from one photo to another as the viewer moves. While many people are familiar with older lenticular images, producing a high-quality flip that is sharp, smooth, and free of visual artifacts requires careful image preparation and exact alignment.
To support this, we have developed our own custom lenticular interlacing software, along with automated tools and production workflows designed specifically for flip lenticular printing. These systems allow us to prepare images quickly and consistently while maintaining tight control over quality. In addition, we have developed what we believe to be a novel approach to simulating lenticular images using ray tracing, giving us a realistic preview of how a lenticular will appear from different viewing angles before it is ever printed. This helps reduce guesswork and ensures the final product behaves as intended.
Today, 3DReactions focuses exclusively on custom flip lenticular prints, produced in-house with carefully refined processes and materials. Every order is handled with attention to detail and a commitment to delivering a product that looks right in the real world—not just on a screen.
We are a small, hands-on company, and we approach every order with the mindset of a customer—because we are customers too. From product design to communication to problem-solving, we ask one simple question: “If this were mine, what would I want?” That philosophy guides how we work and how we treat the people who trust us with their images.
Here are some answers to the questions we receive the most about our services. If we missed anything, please do not hesitate to contact us. We’ll be happy to help
We get this question a lot. Simple answer, the url was available while many others were not. We wish the answer was more creative, but that is what it came down to. It sounded better than “3D Beginning”.
We decided once the pandemic hit that we would shelf people scanning. It is an amazing technology, but we have found that 3d modeling can be as efficient without the overhead of scanning equipment.
The largest size lenticular we make is an 11×16 lenticular flip which you can find on on our website here
A “FLOTO” is a combination of the words “FLip” and “phOTO”. To our knowledge, we originally coined the term and have used it to describe our lenticular flips on Amazon, Etsy, and 3dreactions.com.
Yes, a 3D lenticular picture can be made using the left and right images from a 3d camera. Typically these cameras create an MPO file which contains both the left and right images.
Custom Lenticular pictures are the same as a regular stock lenticular that you can find in many small shops. However with a custom lenticular we use your photos to create the 3d, flip, or animation effect.
If you do not know what a lenticular is or are interested in learning. See our lenticular printing page for more details
Well, it ain’t easy:) We print directly on to the backside of our lenticular lenses to get the best and most consistent quality. See more details on our lenticular printing page
You can upload your pictures online during the checkout process. Or you can email them to us at [email protected] if you have any problems uploading.
YES! Exactly, the “tilt cards” as they were called is probably the most well known use of a lenticular picture.
