Biocompatibility is the ability of certain materials to act with an appropriate response to the biological environment in which it is used. The term biocompatibility is mainly applied to medical materials that are intended for direct, brief or prolonged contact with internal tissues and fluid

Many 3D printer components come in two options: 12 V and 24 V, and so do 3D printers themselves. This characteristic has to be kept in mind when any upgrades are made to the 3D printer, such as replacing the extruders, hotends or any components for these. But what does all that imply for the

Parameters determining adhesion to the printing baseLa correcta adhesión entre la pieza y la base es fundamental para evitar fallos durante la impresión. La unión entre la primera capa de impresión y la superficie de la plataforma cumple dos funciones básicas:Keep the part in a fixed position

During printing, the extruder pushes the filament into the hotend, where it will be melted and extruded through the nozzle orifice. During this process, pressure is created inside the nozzle which forces the plastic out through the nozzle.However, once the extruder stops pulling the filament,

Last week we were present at the International Additive Manufacturing and 3D Printing Fair (Addit3D) held in Bilbao, where we presented our latest innovations in professional additive manufacturing equipment.Among other novelties, we presented the new equipment from Raise3D, which has expande

One of the basic components in any FFF 3D printer are the motors. They are responsible for making the necessary movements to position the print head, as well as for pulling the filament in the extruder.The motors used are stepper motors, the most common types being NEMA 17 and NEMA 23.Image 1

All plastics, when extruded at high temperature, undergo a shrinkage during cooling which can be between 0.3 % and 4 %. This shrinkage can cause deformations, if the cooling is not smooth and homogeneous, giving rise to problems such as warping, delamination of layers or dimensional deformati

Additive manufacturing has many advantages, including the possibility of printing sets of parts in a single print or complex geometries such as a thread. However, in the latter case, the thread design is not made so that there is the possibility of a regular assembly since, being made of plas

FFF printing technology is the lowest cost 3D printing solution, as well as being reliable, accurate and easy to use, making it the ideal technology for professional, school and home use, and the most widely used 3D printing technology in use today.Among the wide variety of FFF 3D printers on

The hotend is one of the most important components of a FFF 3D printer and the one that suffers the most wear and tear. It is essential to carry out proper maintenance and check it periodically to check its condition.There are multiple types of hotends, both stand-alone (e.g. E3D V6) and inte

Pellet printing, also known as fused granulate fabrication (FGF), is mostly associated with injection molding, but it is also widely used in FDM 3D printing, especially under professional or industrial conditions. It allows the user to create custom mixes based on the chosen base polymer and

When preparing a file for printing, it is very important to know the basic parameters and how they work. The number of parameters available in todays laminating software is increasing, however, unless you have an in-depth knowledge of the software and the technology, it is advisable to start

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... These are just some of the possible applications that 4D printing te

The aerospace industry is a highly demanding environment. It requires impeccable elements that are going to be able to withstand continuous wear, and high pressure and high temperature conditions. There is constant innovation and research going on to make sure the components are strong, resis

Electrostatic discharge is a common phenomenon in nature. It can be provoked by an electrical short (short circuit), a dielectric breakdown, or when contact occurs between two electrically charged objects (static electricity), resulting in a sudden and short flow of electric current. ESD is c

The facemask, the first line of defence against the spread of COVID-19, a simple device designed to protect against inhalation and transmission of infectious agents, has affected the lives of billions of people around the world.Since the global pandemic began, the use of facemasks has been a

Have you ever wanted to create something with your 3D printer that included electronic components? Perhaps sensors, conductive traces or shielding against radio frequency noise?The FFF/FDM conductive filaments for 3D printing have been designed for users interested in combining 3D printing an

Education through entertainment has been applied for more than 50 years, but it is now reinventing itself by introducing new possibilities and ways of learning thanks to new devices and tools.Thus, it is possible to foster STEAM skills in children and teenagers by achieving practical and visu

3D scanners are widely used thanks to their potential applications in sectors such as industrial, medical, dental, entertainment, art and others.The most widely used 3D scanners today are structured light scanners because of their versatility combining excellent resolution, high accuracy, hig

As it could not be otherwise, 3D printing is also very present in the furniture, interior design and decoration sector. The different 3D printing technologies offer new possibilities and manufacturing methods through which it is possible to create furniture with original and innovative design
