The contact, even for a very limited time, with the heated part causes burns.

  • Page 15: Opening The Package

    Opening the package Your Sharebot Kiwi-3D is equipped with a series of accessories that allow you to make it immediately operative; there is no software because it is open source and constantly updated. Software must be downloaded from the website of Sharebot to always have the latest version.
  • Page 16 Assembling the reel-carrier For assembling the reel-carrier please see chapter 3, figures 9, 10 and 11 of the manual Assembly, recalling that the wire must carry out unhindered and in the direction of the extruder. Unlocking the extruder To avoid damage during transport, the blocking of the extruder is secured with clamps. The clamps must be carefully cut and removed to allow the extruder to move freely.
  • Page 17 Process of 3D Printing Before you start printing with your Sharebot NG it is important to understand how you arrive at a finished object. This allows you not only to know what you need to do to give form and substance to your ideas, but it helps you to identify any constraints and limitations of the technology used by this printer.
  • Page 18 Downloading from internet The net offers many ready-made 3D models, but also in this case there are differences between the models that you “see fine” and those who “print well”. A good indicator of the ability to print the pattern is of the form: the most popular 3D printing is STL (sites that intend to offer printable objects use this format).
  • Page 19 From a 3D model to a printing file The real “secret” of three-dimensional printing is the transformation of three-dimensional object into a sequence of two-dimensional slices that overlaping, reconstruct the object. Imagine a series of slices of bread: If the stack rebuilt the loaf from which they were cut. In the case of 3D printing every slice may consist of two-dimensional shapes not connected together as it is their sum to create the finished object.
  • Page 20 G-Code, a G-Code files is definitely running for the printer for which it was created but could be unus- able with other printers. If it is not clearly compatible with NG Sharebot there try to print files that you find on the net because they may have malicious entries to your printer.
  • Page 21 Storing the files As we have seen, the process consists of the stages of modeling, creation of STL files, slicing into a G- Code file and print. We recommend that you save the template file in the native format of the 3D mod- eling program, so as to keep any primitives that compose the object.

When you have positioned the new wire on the inlet hole and you did it so it hit the drive sprocket, you must press the knob to start dragging and extrusion which reloads the casting chamber and also allows you to expel the remnants of previous material.

  • Page 26: Setting The Printer

    Chapter 4 Setting the printer Your Sharebot Kiwi-3D is a mechanical device built with care both in design and in the Assembly. To keep it in a State of optimal functioning is necessary to compensate for some normal processes of adjustment, for example, due to repeated thermal cycles of extruder motors.
  • Page 27 Preparting the printing bed We remove the clothespins from the glass and extract it from the printer. Sprinkle over a thin layer of spray evenly up to cover the entire surface (light you will have a shiny effect). Now we await the complete lacquer drying and glass are placed on printing and secure it with pegs.
  • Page 28 Calibration The steps in the installation manual chapter 3e, figures 14 and 15, consists in printing of rectangles made with one layer on top, allowing you to assess the adhesion of the material to the print and to figure out if the plan is leveled properly observing the extrusion width must be equal at all points of the perimeter.
  • Page 29 CAD drawn, tolerances don’t fit together properly, it is probably necessary to calibrate the X and Y axes on your printer. The possible X and Y calibrations on your ShareBot NG are of two types, software or hardware: - Recovering of scraps and usage of M99 (software calibration) If you have a scrap on a strap of one of the two axes you will recognize it by checking any hole or circle printed.
  • Page 30 PONTE Y FUORI SQUADRA Putting in tension the extruder’s rubber bands Your Sharebot Kiw-3D is equipped with a cushioned versus pulley sprocket wire drag. This solution allows to compensate for thickness variations that some filaments can have, allowing you to bring the press anyway.
  • Page 31 To work around this limitation, Sharebot Kiwi-3D allows you to select, before printing, the outline of the material that we use. In this way we can create generic G-Code to be printed with the chosen material simply by choosing the corresponding profile.

  • Page 32: Starting The Print

    Pressing the knob you select for printing. Your Sharebot Kiwi 3D will begin with the heating phase and by positioning at the origin of the axes, then when it reaches the temperature you do in a central area of the print and will start with the first layer.
  • Page 33 Modifying printing parameters One of the features of Sharebot NG is the ability to intervene on a number of parameters while printing is in progress. The “Adapt” menu becomes available instead of the “Prepare” (see Chapter 3): This allows you to adapt the selected profile PLA or normal to their compatible materials for behavior and characteristics (v.

If in doubt, do not detach the piece until the temperature has dropped to safe levels before you put your hands inside the printing area.

For this the fill parameter can be varied depending on the outcome you want to achieve. The entry “fill pattern” lets you choose from a drop down menu the texture that you want to fill areas to the (straight, hexagonal, etc.).

  • Page 39 How PLA entails This material, created by processing the pulp plant waste rich in cellulose, comes from many pre- ferred over to ABS, although most subject to high temperatures (over 60° tends to become slack). Printing between 195 and 230 degrees, depending on the additives that have been added to color it and modify its physical and mechanical properties.
  • Page 40 Chapter 8 Consideration about model orientation The possibilities offered by your Sharebot Kiwi-3D are very broad, but like all technological tools, this must be understood and used by applying various measures over time more and more sophisticated. 3D printing technology, promises to create any shape but are frequent cases where a print ends with a big disappointment.
  • Page 41 Just one object? There are cases when printing in one piece is inevitable, but there are as many cases where you can cut into several parts the object to print more easily. An example that you often see on the internet is that the Eiffel Tower: for his height would print a whole small object and with details too tiny to be created from most printers FDM.
  • Page 42 In professiona printers supports are manufactured using special thermoplastic, possible to dissolve through special chemical or thermal baths, filed with a second extruder. Even with Sharebot NG, du- al-extruder version, you can use as supporting material of the “Poly” (polyester) limomene soluble in combination ABS for printing.
  • Page 43 Each type of object has its own range of optimum thickness for printing and only with a bit of experi- ence you can intervene on this knowing what parameter are you going to actually meeting. Our tip is to choose a small enough, but with an articulated form, upon which to pursue a systematic experi- mentation, thanks to which you will be able to see the effect of each variation.

  • Page 44: Cleaning The Printer

    Ordinary Manutention Cleaning the printer Sharebot Kiwi-3D does not require any special maintenance, but, like all machinery, efficiency in- creases if kept clean. - Printing bed: the first layer of the object we print is essential to the success of the press: for this rea- son the printing floor must be perfectly smooth, with a uniform layer of lacquer applied.
  • Page 45 A correct ventilation Your Kiwi-3D is equipped with a cooling fan devoted to electronics, located at the lower left on the front seat: you will notice that when the printer is turned on and stays on at all times. It should make sure that dust or other debris do not obstruct the forced cooling of electronics, blocking in the long run also the functioning of the fan.
