Discover the latest news, tips and tricks about 3D printing. We continually analyze and test new products and materials, in order to ensure the traceability and quality of our entire catalog, sharing our conclusions and our experience.
3D printing inserts
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 obtained using traditional manufacturing techniques. Inserts are an example of this and there are several types of them. In this post we will talk about them.
Open, and enclosed passive/active chamber 3D printers
Temperature related shrinkage is common for materials, also in 3D printing. Various materials can suffer a contraction of 0.3 - 4.0 % during cooling, often resulting in warping, layer separation or size alteration. This is why the right 3D printer - open, or with an active or passive heated chamber - has to be chosen for the right plastic.
NEMA motors. Most frequent problems
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. That is why it is crucial to know how to connect a stepper motor, how to set the current parameters, and which step speed to choose.
Back to face-to-face events at Addit3D
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.
Retractions: configuration and optimisation
Once the extruder stops pulling the filament, the pressure in the nozzle is maintained, which causes a small amount of molten plastic to continue to come out until the pressure is equalised inside and outside. This causes small droplets to appear on the surface of the part and fine threads. To prevent this, FFF 3D printers employ a mechanism known as shrinkage.
How to troubleshoot build platform adhesion issues
The good adhesion of the first layer to the printing base is crucial to a successful printing process. Many factors influence the adhesion quality, such as the type of coating chosen, the adhesion settings in the slicing software, and the temperature and condition of the printing base. Excessive adhesion and insufficient adhesion can be equally problematic.
Which voltage to choose: 12 V or 24 V?
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.
3D Print with Conductive Filaflex
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.
