• 4 RepRapBCN User Manual FFF Technology BCN3D+ is a 3D printer based on fused filament fabrication additive manufacturing technology, consisting in the deposition of melted material layer by layer based on a previously divided digital model. The head makes the necessary movements to deposit a layer of material, then a slight vertical movement to continue with the next layer. The process is

• Fundaciocim BCN3D, 36 RepRapBCN User Manual In this case, try the following steps: 1. Clean the glass to prevent dust or other substances interfere between the base and the piece. 2. Soak the glass surface with a layer of the included adhesive spray 3. Raise the base temperature five degrees celsius. 4. Calibrate the base as shown in section 11 Maintenance. 5. Print the first layer with the hotend closer to the base. To do this, loosen the three screws from the base an eighth of the way or loosen the screw that actuates the Z a

The most commonly file type found is the *.STL format. An STL file describes a raw unstructured triangulated sur- face. The smaller the triangles are, the bigger the resolution and the detail of the 3D model. Obtaining STL fi

• Fundaciocim BCN3D, 30 RepRapBCN User Manual 8. FIRMWARE What is a firmware and when to update it? The firmware is a software needed to control a hardware. Namely, it is the internal program that controls your BCN3D +, and allows it to perform its functions normally. The BCN3D + is delivered and installed with the latest firmware version published on the web. Its basic functions are: On the one hand, converting .gcode files to useful instructions for printing, managing the motor drivers and target temperatures. On the other hand, it is also responsible for managing machine peripherals such as the screen, allowing you to inte- ract with it without connecting the printer to a computer

• Fundaciocim BCN3D, 34 RepRapBCN User Manual It’s difficult to remove an object once it’s done Once a print is finished, it’s sometimes difficult to pull it out of the platform: • Let the base cool down, the colder it is, the less adhesion. • Carefully place a cutter below the part and use it to slowly remove the object. • It is highly recommended to remove the cristal base by loosening the white screws. If you try to extract the printed part directly without removing the glass first, you could be forcing the screws and/or misaligning the platform. Motors do not rotate correctly (adjusting the pololus) From Hom

To achieve that, there are three screws available to calibrate its orientation. There’s a risk of the nozzle hitting the hotbed glass or the first layer not sticking on its surface when decalibrated. The following steps must be followed: 1. Click Autohome (Prepare/Autohome) so the printer axes move to their initial position. The first time, caution should be exercised because the nozzle can collide with

A brief description of the materials currently accepted follows: PLA PLA (polylactic acid) is the quintessential material for 3d printing, thanks to its ease of use through deposition.

• Fundaciocim BCN3D, 38 RepRapBCN User Manual 11. MAINTENANCE Given the machine characteristics, it is very important to periodically check the different components so we don’t lose print quality and to avoid errors. Calibration BCN3D+ is marketed fully asembled and calibrated, but it is possible that it might require recalibration of its axes over time. The process is simple if the following steps are taken: • X axis calibration a) With the calibration tool, measure the X axis bars height from the aluminum sheet base b) Adjust the height at both ends of its horizontal axis by ma- nually rotating
