![]() The process of modifying the shape of a 3D printed part with SMP TPU filament consists of placing the 3D printed part in a container of hot water until it reaches its glass transition temperature. Thanks to its special composition and Shape Memory Polymer technology, parts printed with this filament can be modified manually, allowing them to acquire another shape and maintain it over time. An example would be Convena's TPU SMP: a 4D filament with a composition based on TPU (thermoplastic polyurethane) that allows post-processing to modify the shape of 3D printed parts. Polymers that remain rigid at room temperature and offer special properties when they reach the glass transition point. However, there are some very interesting ones. As this is a fairly new technology, the materials available are not as varied as those used for standard 3D printing. The key to 4D printing is not so much the process, based on the familiar 3D printers, but the materials. This is precisely the difference between 3D and 4D technology: the ability of objects to transform over time without human intervention. That is, obtaining an object through 3D technology that, thanks to the properties of the material from which it is made, is able to change when subjected to an environmental stimulus. ![]() Inspired by the principle of self-assembly, 4D printing is the process by which a 3D printed object is transformed into a different structure by the influence of external energy input such as temperature, light or other environmental stimuli. They developed a material based on natural structures, such as plants, which was injected with cellulose fibres during the printing process. Meanwhile, a study by the Wyss Institute (part of Harvard University) has succeeded in printing an object that, when it comes into contact with water, changes its shape, resulting in a kind of flowering of its ends. Its purpose is to combine technology and design to invent programmable materials and self-assembly technologies with the aim of reinventing construction, manufacturing, product assembly and performance.

Image 1: 4D printed claw modifying its shape. These are just some of the possible applications that 4D printing technology is envisaged to realise. I just wish I had half the CAD talent of Stepan so I could design more of my own stuff.What if pipes could automatically fix themselves if they crack or break, or clothes could change according to the weather or the activity the user is doing? Furniture that assembles itself, prostheses that adapt to growth. Why? Because no one else in my area has one! Its unique, cutting edge and other than buying the file.I made it. But I have more satisfaction with this P-51 and I haven't even flown it yet. That EFX is one of my favorite speed planes and is blistering fast with my rare bear motor in it. ![]() I spend hours printing things I could easily buy from the dollar store. I don't know about you guys, but I have a basement full of impractical things and my printer is one of them. from RCGroups forum - I cant beleave we are even having this conversation! We all printed this thing because we could. This design style just seems to be custom catered for things like a Mig-15 or a curvy SR-71 Way more satisfying than buying it from china! (Lower case "c" intended) I love the challenge of printing this aircraft. The cool factor of having all the internal architecture within the wing and fuse sold me. I had to get the S3D to make it work the way it was designed. I just downloaded the mustang last night.
