There are numerous certified biocompatible 3D printing materials, especially resins, available on the market. But the certified biocompatibility of a material does not mean a 3D printed piece will have the same properties.

Printing 3D models encourages the development of skills by involving students in the process and getting them to adapt to changes and correct mistakes. In this way, learning is not only based on observation, but also on printing files that you have created yourself.

The extruder is the element responsible for pulling the filament into the hotend in such a way that sufficient pressure is generated inside the hotend so that the molten material flows constantly and homogeneously through the nozzle.

In SLS 3D printing, part orientation affects quality. Avoid overlapping layers and position openings upwards. Move parts in XY plane, tilt flat surfaces and blocks at 45° to prevent heat build-up.

Lamination is a key process in FDM 3D printing. In this article, you can find a selection of the 5 most used and recommended free lamination software for FDM 3D printer users at the moment.

To avoid problems when 3D printing, it should be taken into account that a possible source of failure may be the poor position of the spool and its path to the extruder. Therefore, in order to facilitate the work of the extruder, the minimum tensile strength of the filament should be sought.

The evolution of 3D printing and the development of new materials are enabling innovative applications in the medical sector. Among the various 3D printing products developed for the medical sector, antibacterial filaments stand out, enabling the manufacture of parts with specific applications.

If we want to use a resin whose manufacturer differs from that of our printer, we must take into account 2 parameters: the wavelength for which it has been optimised (365 nm, 385 nm and 405 nm) and the technological compatibility (SLA and LED/DLP).

In order to be able to print in 3D FFF each layer on top of the previous one, it is usual to use printed support structures that serve as a support base for the previous elements. These structures are known as supports and in this post we will see each type, their configuration parameters and the problems that soluble supports can present.

There are a number of mechanical problems in FFF 3D printers that can appear and need to be checked, that's why in this post we explain the most common mechanical problems and, in some cases, how to avoid or solve them.

Ten years ago, German engineer Kai Parthy launched LayWood, the first wood filament in a market dominated by standard PLA and ABS. Kai Parthy has continued to explore his experimental interests and expand his product range.

In this post we will talk about delta 3D printers, their advantages and disadvantages as well as their differences and similarities with Cartesian 3D printers. In addition, we will show you some of the best rated Delta 3D printers on the market.
