These instructions are for the Cliever 3D printer. This printer is now under the responsibility of Prof. Guilherme Raffo, so you must ask for his authorization in order to print any piece you require.

For additional information on the printer, please visit the Cliever webpage.


To print a 3D piece you need:

  • The Cliever CL1 3D printer
  • A PC with the Cliever software installed
  • The STL model of the piece to be printed (maximum dimensions: 180x180x100 mm)
  • Plastic filament
  • PVC glue for fixation of the plastic to the printing surface

Calibration of the printer

Calibration is usually required after some pieces have been printed.

  • Turn on the printer and connect it to the PC using the USB cable.
  • Open the Cliever software and click on "Conectar".
  • Select calibrate in the software window.
  • Place the glass on the correct place and clic on "Calibrar".
  • Follow each of the calibration steps provided by the software.
  • You will need the PVC glue in order to print verification samples of the calibration quality.

Saving the project for printing

Once you have the STL, you can open it using the Cliever software.

  • In the software, open the piece you want to save
  • Click on the printing definitions "Definições de Impressão" and simulate by clicking on "Simular"
  • After the simulation, you can export the piece as a printing file with extension .cl

Printing pieces

  • Open the Cliever Lab software and the piece to be printed
  • Apply a thin layer of PVC glue on the printer's glass, this helps to support the piece throughout the process
  • Mount the glass on the printer and adjust using the available clips
  • Turn on the printer and connect it to the PC and to the Cliever software by clicking on "Conectar".
  • Define the printing parameters by clicking on "Definições de Impressão" and print the piece by clicking on "Imprimir"
  • Check if the piece is being correctly printed. The software screen shows the printing progress, so if it is similar to the actual print, then it is likely that your piece will be correctly printed
  • Wait for the printing process to finish (the software provides the total and remaining printing time by clicking on the info button)
  • At the end of the printing process, wait for the printer's table to cool down
  • ALWAYS remove the supporting glass before taking the piece out
  • After taking the piece out of the glass, remove the glue from the glass by using the spatula. Take out a corner of the applied glue and then remove the glue layer by hand

Replacing the plastic filament

The cliever software has an option to replace the filament. Follow each step provided by the program in order to install the new filament cartridge.

Verifying and correcting STL files

The Netfabb software helps to correct defective STL files. It can be downloaded through their website.

  • Open the desired stl file
  • If the model is defective, an exclamation sign appears on the main screen of the program
  • You can use the heal tool to fix the problem. It is recommended to perform a default heal
  • Accept the corrections and export the fixed stl file
