The project is about fabrication of 3D Printer. We are interested in creating 3D printers locally and economically in Pakistan for the development and advancement of manufacturing sector of Pakistan.

Our project is a startup base project, we are interested to establish a startup around our project. We have the aim to manufacture 3D Printers, 3D Printer filaments, injection molding machines, extruder machines, filament machines, cnc machines, laser printing machines locally and economically in Pakistan.

3D printing, also known as additive manufacturing, is a method of creating a three dimensional object layer-by-layer using a computer created design.

3D printing is an additive process whereby layers of material are built up to create a 3D part. This is the opposite of subtractive manufacturing processes, where a final design is cut from a larger block of material. As a result, 3D printing creates less material wastage.

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone.

This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts Now, you can create a complete model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.

Additive manufacturing process or 3D printing process is now becoming more popular because of its advantages over conventional processes. A 3D printer is a machine that create objects out of plastic, nylon like many other materials.3Dprinters now days available are not so portable and also they are very costly. By analyzing this problem, we are trying to make a portable 3D printer The cost of this printer will be very less compared to other 3D printers. Making low cost 3Dprinter with price 15% lower than market.

Project Objectives

Our objective is to build a user friendly, low powered 3D printer which can print different variety of complex parts, and then work on it to make it available at the Industrial scale in Pakistan. We have chosen i2M4 as our model because of its simplicity, small size, high accuracy, inexpensive parts, and smartness which makes it as the most useable 3D Printer ever in the 3D Printing industry.

The targeted size of our printer and printing volume is 200mm cube which we have achieved 100%.

The primary goal of this project is to design a 3D Printer.

Make it SMEA where the Designers like me can share their ideas to help society through designing 3D Printers,

Turn it into a complete working company where the designers like me can design 3D Printers for helping the society in different fields.

Project Implementation Method

The first step is to select one of the additive manufacturing process among many process of 3D printing our is FDM. Then an appropriate mechanism is selected for X, Y and Z axis movements, considering various factors such as cost of fabrication, simplicity of design, synchronization, accuracy etc. Once the mechanism is selected the next step is integration of electronics and software then the machine is designed and fabricated. The last step is, synchronization of mechanical, electrical and software elements of the machine. The FDM technology is clean, simple to use and it is environmentally stable. Complex shapes and intricate parts can be printed. FDM is at the very entry of the market as it mainly used by individuals. FDM is an affordable 3D printing process compared to other 3D printing technologies. Presently mechanisms such as, for example, SCARA, Cartesian, Polar, Delta and so on are utilized as a part of development of FDM 3D Printers. We have chosen cartesian arrangement of developments, where the bed moves in the vertical heading i.e., in Z pivot bearing and the extruder spout moves horizontal way i.e., both in X and Y hub course. Z hub development on such a 3D printer is extremely exact and requires low increasing speeds, however the bed should be lightweight with a specific end goal to look after precision, which makes it harder to include a completely programmed bed leveling framework. Controlling a straight Cartesian framework like this is mechanically straightforward and furthermore generally simple from a product point of view, which is the reason most 3D printers available today utilize this kind of plan. The Cartesian arrange frameworks has for quite some time been utilized for instruments like plotters, CNC processing machines, and 2D printers 3D Printer electronics are controlled by an inexpensive CPU such as the Atmel AVR processor. Atmel processors are what Arduino-based microcontrollers use. These processors are exceptionally weak contrasted with even the normal laptop you find in the landfill these days. However, so they do run primitive software. This primitive software they run is the firmware. The entire software chain that makes the 3D Printer work, the firmware portion of it is the closest you get to actual programming. In fact, the term for what you are doing with firmware is called cross compiling.

Benefits of the Project

3D printing-based manufacturing offers a lot of benefits compared to traditional manufacturing methods. These include those related to design, time, and cost, amongst others.

3D printing allows for the design and print of more complex designs than traditional manufacturing processes.

3D printing can manufacture parts within hours, which speeds up the prototyping process. This allows for each stage to complete faster. When compared to machining prototypes, 3D printing is inexpensive and quicker at creating parts as the part can be finished in hours, allowing for each design modification to be completed at a much more efficient rate.

Print on demand is another advantage as it doesn’t need a lot of space to stock inventory, unlike traditional manufacturing processes. This saves space and costs as there is no need to print in bulk unless required.

The 3D design files are all stored in a virtual library as they are printed using a 3D model as either a CAD or STL file, this means they can be located and printed when needed. Edits to designs can be made at very low costs by editing individual files without wastage of out-of-date inventory and investing in tools.

The main 3D printing material used is plastic, although some metals can also be used for 3D printing. However, plastics offer advantages as they are lighter than their metal equivalents. This is particularly important in industries such as automotive and aerospace where light-weighting is an issue and can deliver greater fuel efficiency.

Also, parts can be created from tailored materials to provide specific properties such as heat resistance, higher strength, or water repellency.

Depending on a part’s design and complexity, 3D printing can print objects within hours, which is much faster than molded or machined parts. It is not only the manufacture of the part that can offer time savings through 3D printing but also the design process can be very quick by creating STL or CAD files ready to be printed.

3D printing is being used in the medical sector to help save lives by printing organs for the human body such as livers, kidneys, and hearts. Further advances and uses are being developed in the healthcare sector providing some of the biggest advances from using the technology.

Technical Details of Final Deliverable

The design of the model has to be done in software where the actual model

with the required dimensions is developed so that it can be used to print the model.

To develop and fabricate thmodel there are many process and parameters involved

mainly design of the model. The design process started by keeping the print

volume as a basic design parameter. As the objective of the project is the

construction of economical and sizable 3D Printer, a print volume of 200 x 220 x

220 mm3 is selected. The 3 – Dimensional motion is achieved by synchronization

of movements in X, Y and Z directions. Hence mechanism of our 3D Printer is Z

plus core XY. This mechanism uses 5 stepper motors, one for X-axis movement, one for Y-axis movement

(to and fro movement), two for Z-axis movement (Vertical movement) and one for

Extruder filament. This mechanism uses the single motor to control lead screws to

which the print bed is connected to the movement in Z – direction. The lead screws

are driven by the motor which in turn moves the bed in the vertical direction. Two

motors have been used here because the print volume is large, there will be a

disruption in the movement if only a single motor is used. The conceptual design

has been initially visualized in Sketch-up software.

Selection of Motor for X and Y axis

Assumptions:

Constant speed of the motor = 400rpm=6.667rps v = r ?

= [2?N]/60

= 41.908rad/s

Therefore;

400 = r*41.908 r = 9.547mm Torque = Force*Radius

Force = 41.87N (considering NEMA 17 stepper motor having torque = 0.4Nm)

X – axis Movement

 Figure 6.3 shows the rendered CAD model of the mechanism of Lateral

movement. It consists of the pulleys, timing belt ,carriage, cylindrical rods, and

extruder nozzle (used in FDM process) arranged as shown.

The rotary motion of motor is converted into linear sliding motion by

timing belt – pulley connection as shown. The X – axis rods are fixed to the

carriages with the help of holes in side face of the carriages.
