By designing and 3D printing this wallet, i found my best settings to print TPU-95 filament! After tweaking, these settings serve as a good foundation for my future flexible 3D prints.

In the realm of 3D printing, enthusiasts and professionals alike are constantly seeking materials that offer both durability and flexibility to bring their creations to life. Among the plethora of options available, Thermoplastic Polyurethane (TPU) filament has emerged as a game-changer, revolutionizing the way we approach 3D printing projects.

TPU is a type of elastomer that combines the advantages of plastic and rubber, making it exceptionally flexible, durable, and resistant to abrasion. Its unique properties make it an ideal choice for a wide range of applications, including prototyping, functional parts, prosthetics, and even fashion accessories.

Only the first six layers were printed at a lower speed than the rest on top. This to get a solid start with good adhesion to the print bed.

The video below shows which print settings i used to print a wallet. I show two 3D printed wallets together with these settings. In a nutshell: only the first six layers were printed at a lower speed than the rest on top. This to get a solid start with good adhesion to the print bed. After these layers, everything was printed at a higher speed with a little more filament flow to speed up the process.

One of the things you may come across is that you want to edit an STL file you downloaded. Some sizes may not fit your wishes and you want to change that. Here you can read how i fix this!

As i use FreeCAD for my 3D designs, i like to use it as much as possible. So i also modify STL files with it. However, sometimes an STL model can be unsuitable for FreeCAD. It can be too heavy or it has some other errors inside it.

I always edit my STL files with FreeCAD. But there are other options like Blender or Meshmixer for example.

I created a few videos about editing STL files and here’s one of them below. In this video, i use the Part Design workbench, instead of the Part workbench. The Part Design workbench is one of my favorite workbenches to create designs with.
