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.

3D printing allows the production of complex parts, but like any technology, it has limitations. These problems can be overcome by relying on mechanical elements such as inserts obtained using traditional manufacturing techniques.

Temperature-induced shrinkage occurs in 3D printing materials, ranging from 0.3% to 4.0%. It often leads to warping, layer separation, or size changes. Selecting the appropriate 3D printer, whether open or with a heated chamber, is crucial for each plastic type.

In any FFF 3D printer, the stepper motors are indispensable. Their task is to position the print head, as well as to pull the filament in the extruder. The most common problems involve the power driver or the connection

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.

After the extruder stops pulling filament, pressure remains in the nozzle, causing molten plastic to continue flowing until pressure equalizes. This results in droplets and fine threads on the part surface. To mitigate this, FFF 3D printers utilize a mechanism called retraction.

First layer adhesion is key for successful 3D printing. Factors like coating type, slicing software settings, and base temperature affect it. Balancing adhesion is crucial; too much or too little can cause issues.

The most common operating voltage of DC devices is 12 V or 24 V. Both voltages have their benefits but the most important thing is to match the 3D printer’s output voltage to that of the hotend, the extruder, fans or heatbeds. Overpowering or underpowering of the components can have serious consequences.

Conductive filaments are ideal for manufacturing electrically conductive parts or components and for creating wearable devices. Based on its capabilities, results with beneficial properties for many industries will be obtained. The Spanish company Recreus is committed to this material and offers the user a series of tips when using its Conductive Filaflex filament.
