A year ago, and after more than three years of research and development, the world of 3D printing marveled at the world's first graphene conductive filament manufactured by the US company Graphene 3D Lab. Graphene filament is already a reality in FDM/FFF 3D printing which makes possible a world of possibilities.

One of the first big questions that comes up when starting in 3D printing is; How much does it cost to make a piece in 3D? Well, let's try to explain the main costs that must be attributed to the printing of a piece to calculate its actual cost of impaction.

One of the main doubts in the day to day among users of 3D printing is to know the density of the filament that they will use to know how much material they will consume, and therefore how much material they will need to print a piece in 3D. The (absolute) density is a scalar quantity referred to the amount of mass in a given volume of a substance.

The main areas of an extruder are the heating block and the dissipation area, although these are formed in turn by several parts. To understand the basic operation of the extrusion process of the filaments in 3D printers, it is essential to understand the functionality of both areas.

In the FDM 3D print the correct lubrication of the moving parts of the 3D printer is critical because it can directly affect the final quality of the printed pieces. If the rods or bearings are poorly lubricated 3D printer, the print carriage may tend to move to blows and generate an annoying noise. In this way you lose accuracy in positioning the print head.

The prestigious engineer Kai-Parthy has passed a new barrier in the world of 3D printing filament to achieve develops the first reflective filament for 3D printing FDM. Reflect-o-Lay filament is created relying on the principle of retro-reflection of light.

Since most users know 3D printing, one of the main parameters that directly affects the finished parts made with 3D printers FDM is the print speed. So the faster print speed will get worse finish and the smaller the better finish. Therefore, the finish can claim to be directly proportional to the time of printing.

In many cases PLA and ABS are not suitable for engineering parts or parts that have to be suitable for specific high performance applications. The prestigious US manufacturer of Taulman 3D filaments is at the forefront of innovation in engineering materials for 3D printing.

Last Saturday, October 17, the Mini Maker Faire was held in Santiago de Compostela for the first time. In it we met more than 70 makers from all over Galicia to showcase the latest creations in robotics, science, mechanics, 3D printing, drones, laser cutting or the latest innovations in gastronomy and crafts, among other areas.
