3D Lenticular printing has become more affordable because of the ever lowering prices of digital printing equipment found in homes and offices. There are many downloadable software products on the market designed for this special form of printing; some free and some for a medium to high price. By and large these products serve one main purpose; i.e. to interlace pictures to be viewed through lenticular sheets.
This article tries to demystify the underlying working of interlacing software. By understanding how pictures are interlaced and then combined, you will be able to appreciate the principles of lenticular printing better. This knowledge will also help you identify with the terminology used in many other software products.
The principle of 3D lenticular printing is based on binocular disparity. When we view an object, our left and right eyes see a slightly different image and when combined the brain perceives the sense of depth. In traditional printing, information can only go left-and-right and also up-and-down. The in-and-out information is lost. In order to perceive in-and-out, we need a way to present the same object with a slight binocular disparity as shown in the picture on the right.
What we have shown so far are the fundamentals. In reality, professionals in the industry probably would not create lenticular prints this way. They would most likely use ad hoc software. Listed below are some of the software we have used.
3D printable models may be created with a computer-aided design (CAD) package, via a 3D scanner, or by a plain digital camera and photogrammetry software. 3D printed models created with CAD result in relatively fewer errors than other methods. Errors in 3D printable models can be identified and corrected before printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
Once completed, the STL file needs to be processed by a piece of software called a "slicer", which converts the model into a series of thin layers and produces a G-code file containing instructions tailored to a specific type of 3D printer (FDM printers). This G-code file can then be printed with 3D printing client software (which loads the G-code, and uses it to instruct the 3D printer during the 3D printing process).
To become a viable industrial production option, there are a couple of challenges that 4D printing must overcome. The challenges of 4D printing include the fact that the microstructures of these printed smart materials must be close to or better than the parts obtained through traditional machining processes. New and customizable materials need to be developed that have the ability to consistently respond to varying external stimuli and change to their desired shape. There is also a need to design new software for the various technique types of 4D printing. The 4D printing software will need to take into consideration the base smart material, printing technique, and structural and geometric requirements of the design.
The application of 3D printing for the representation of architectural assets has many challenges. In 2018, the structure of Iran National Bank was traditionally surveyed and modelled in computer graphics software (specifically, Cinema4D) and was optimised for 3D printing. The team tested the technique for the construction of the part and it was successful. After testing the procedure, the modellers reconstructed the structure in Cinema4D and exported the front part of the model to Netfabb. The entrance of the building was chosen due to the 3D printing limitations and the budget of the project for producing the maquette. 3D printing was only one of the capabilities enabled by the produced 3D model of the bank, but due to the project's limited scope, the team did not continue modelling for the virtual representation or other applications. In 2021, Parsinejad et al. comprehensively compared the hand surveying method for 3D reconstruction ready for 3D printing with digital recording (adoption of photogrammetry method).
The US Department of Homeland Security and the Joint Regional Intelligence Center released a memo stating that "significant advances in three-dimensional (3D) printing capabilities, availability of free digital 3D printable files for firearms components, and difficulty regulating file sharing may present public safety risks from unqualified gun seekers who obtain or manufacture 3D printed guns" and that "proposed legislation to ban 3D printing of weapons may deter, but cannot completely prevent, their production. Even if the practice is prohibited by new legislation, online distribution of these 3D printable files will be as difficult to control as any other illegally traded music, movie or software files."
Attempting to restrict the distribution of gun plans via the Internet has been likened to the futility of preventing the widespread distribution of DeCSS, which enabled DVD ripping. After the US government had Defense Distributed take down the plans, they were still widely available via the Pirate Bay and other file sharing sites. Downloads of the plans from the UK, Germany, Spain, and Brazil were heavy. Some US legislators have proposed regulations on 3D printers to prevent them from being used for printing guns. 3D printing advocates have suggested that such regulations would be futile, could cripple the 3D printing industry, and could infringe on free speech rights, with early pioneer of 3D printing Professor Hod Lipson suggesting that gunpowder could be controlled instead.
Thingiverse Education provides hundreds of free 3D printing lessons that make teaching with a 3D printer easier and more effective for a variety of grade levels and subjects. It also provides a community where educators can exchange best practices or remix projects.

The use of 3D printing in industrial applications is usually referred to as additive manufacturing (AM). Additive manufacturing involves a layer-by-layer addition of material to form an object, referring to a three-dimensional file, with the help of software and a 3-dimensional printer. A relevant 3D printing technology is selected from the available set of technologies to implement the process. The last step involves the deployment of this process across different industry verticals based on the necessity.
The demand for scanning software is estimated to grow on account of the growing trend of scanning objects and storing scanned documents. This ability to store the scanned images of the objects irrespective of their size or dimensions for 3-dimensional printing of these objects whenever necessary is expected to drive the scanning software segment during the forecast period. The scanning software segment is expected to register the highest CAGR of 21.7% from 2022 to 2030 and generate considerable revenues during the forecast period in line with the growing adoption of scanners.

Quite a lot of the images seen in 3D lenticular prints are not true stereoscopic images at all: they are conventional 2D images whose elements have been separated into layers, with software that fills in the edges of the resulting holes and simulates depth between the layers (and can be achieved easily with the latest version of Photoshop, with its 'Content Aware Fill' tool). This effect works surprisingly well, even though each layer is actually flat.
The production stage of lenticular imaging converts the images into interlaced strips with the appropriate measurements for the lens material, printing process, print size, resolution and halftone setting.
3DZ is one of the first lenticular software suites and is still being developed in 2015. Its 3D Lenticular Suite 2015 includes applications to do pretty well everything needed at the creative, production and output stages. Its current interlacer is called V7.
Imagiam, in Barcelona, has been selling its Lenticular Effects modular suite since 2000. This runs on Mac OSX or Windows and offers the creation, interlacing and printing of lenticular images with different effects: flip, zoom, movement, animation, 3D, etc. Developer David Garcia says it is used in demo suites by Heidelberg, KBA and Canon/Océ Denmark. 2b1af7f3a8
