1. Introduction to the course: Hello, everyone. I'm Robin John, director of multiple tech startups and a physicist allocated to markets including, but not limited to, aerospace additive manufacturing. U. A. V s Robotics and Automation three D Printing is a revolutionary prototyping technology that has found news cases in almost every industry of worked and beat education to both Student interest in technology off on innovation to industries from aerospace, consumer electron ICS are requiring product development and prototyping. You could be an architect wanting to showcase your design and three D to your manager. Or you could be an entrepreneur who needs to three d Print a casing off your M V P. You could just be a three D printing for a hobby on might randomly print and object that you might need once in a while, for example, have a look at this. So Nespresso capsule older that I recently printed a similar holder would cost me around 15 years at a retail store. Meanwhile, printing at A to my major expense was only the billy material, which costed me less than 50 cents. So this course is for you for a beginner curious, about three D printing or a professional who wants to pursue additive manufacturing as a career. If you're a non technical executive interested in technology and innovation, our three D printing is probably one of the most fascinating technology can start, but so the scores is aimed at B six Off medium at the imprinting means fused deposition modeling the most widely used three D printing method. The aim is to gain an understanding of the technology inside out. So we will be looking at the construction of fun of the popular Die by three D printing. Gets called Bruce I Tree on understand the purpose of each hardware component that goes inside a three D printer. Next, we look at some slicing Softwares and understand the basic principles on how they operate and try to set different parameters such as temperature extrusion, wall thickness supports and see how the parts behave. We won't be going into designing or prototyping ourselves. We leave that part for another workshop. We'll use stock three d got files from websites. Such a sting givers to three different and understand the perimeters after we'll talk about the maintenance of the your machines. Andi, I'll give you my personal troubleshooting pointers as well. Oh, and finally we'll close the chapter with some industry applications and use cases revolving around three D printing eso. Let's get salad. 2. History of 3D Printers: Hi. Welcome back. Let's talk a bit about the history of three D printing and how it all started. In 1981 Hideo Kodama received the Peyton for the first functional three D printer. A solid printed model was built up in layers, one after the other, depositing Morton plastic one on top of the other. Sounds familiar. That's exactly how all over FTM printers work. Three years later, in 1984 Charles held me three D printing history by inventing Steer a ta graffiti, steal a ta graffiti, also known as still photography. A parities or SLE or optical fabrication photo Solidification or more commonly, resin printing uses a different kind of acrylic based material known as photo polymer on s capable to plant an incredible quality and finish the liquid Photo polymer is exposed to UV laser beam. The light explores portion will instantly turn into a solid piece of plastic moulded into the shape of your three d design. In 1992 a startup DDM produced the world's first selective sent laser centering machine, also known as a Selous, which shoots a laser into a powder instead off a liquid. These are the major kinds of three D printing solutions today that we'll discuss later in greater detail. By 2003 D printing was widely used across industries, medical industry, bio printed, ah, functional miniature kidney, prosthetic arms and even blood vessels. Aerospace industry found its applications and rapid prototyping. NASA was one of the major provenance of three D printing, but still the three D printing industry was very nascent on a machine could run in dense off thousands of dollars, if not hundreds of thousands of dollars. This was when three D printing met with the open source movement. In 2005 Dr Adrian Boyer launched the Reply Project Off, which is an open source initiated to create three D printer that could basically build itself or at least spent most off its own parts in 2008. Released Darvin is a self replicating printer that's able to just do that. You can find all the resource progress and contributions after plopped a torque. The printer that we will use today similar to prove Sahai Tree, a printed up originated from the Reply Project On underwent several operations from its predecessor, Prue. Some Mendel was released in September 2000 and do the you can. Three different in multi color print with any filament that you like, including carbon fiber, rubble of wood or even metal. Companies are using three D printing to make production greed items without having to spend in costly manufacturing processes like injection molding, especially if the production numbers are low on it. Rations or customization requirements are high. Today, a three D printer could cost as less is a few $100 can be equipped in every home can be used for D today functional prototyping. 3. Hardware Components of an FDM printer: hello again in this section, we'll talk about the competence that go in a typical three different, more or less. All of the imprint does work on a similar frame book. So no matter how expensive or cheap, big or small your three D printer would be, you would be able to understand the functionality of your mentor using this type the print of you're looking at today, it's called in it. It is one of the cheaper options available on a shipped worldwide. Now the print quality from the printers average. But the main reason for using this winter and this demonstration is because it is one of the most d i y gets available in the market. Assembling such a printer can be a great learning experience, so let's get started. Let's discuss the components that will be needing for building or three different. Oh, in tools will be needing screwdrivers. Child nipper, Alan Keyes on an open spanner. We will use entry an M four screws off different lens nuts, spacers on a meat nuts and spacers for treaded Lini roads. We have a power called on a power supply with the 12 old 15 AMP. Power output. The display board we're using today is a 2004 LCD screen widely used with microcontrollers such as order, you know, for the guy projects, and it's quiet, easy and cheap to procure. Hotbeds are used in three D printers because they dramatically improved the print quality by keeping the extruded plastic warm on. Does preventing warping warping means that the sides of the print shrinks? And that's causing the planet to lose its grip from the surface, which is one of the main cause for most field three D prints. It's also recommended to use painter's tape or captain tape to improve addition. We have some yellow pinto step in our hotbed hard, but is mounted on top of for mounting plate. This allows the leveling off for bed with a simple, platform leveling spring screw system. We have five motors in three D Pinto X Axis motor helps the X axis motion of the X Trudeau , which is left or right motion. Why access motor moves the hotbed, front or backwards? There are two zed access motors that move the roads up and down to help extrude a move in the said axis and finally extruded has a moto that pushes the filament through the nozzle using addict Dr Extrusion system. There are two parts to annex Trudeau a golden on the Horton. The coolant is the part that physically forces the filament forward on this, typically comprised off a gear bearing on a stepper motor, it is fed into the Horton. Very. It'll first passed through a multi area to liquefy the filament until it is forced out of nozzle limits. Searches or end stops are electrically connected to the end stop sport off the mother boot on will provide a signal than and stops searches pressed. This makes the printer of air, if it's and positions to impose prince size restrictions, the fan and the heat sink attached to the side of the direct drive. X. Trudeau is essential to keep the terminal isolator cool so that the filament only Mendels at the end of the extra odor. The second fan blues era, the extruded plastic, to solidify it quickly without this different may sad down or even sometimes break. There are two kinds off linear roads that we will be using threaded on smooth roads. Linear bearings allow the extra order on the hot, better slight over smooth linear rods. Timing belt allows the motor to transmit the moment onto the extrude, a modern or the hotbed. A drive here is attached to the stepper motor. The belt fits into the notches of the gear, preventing it from slipping and allowing it to rotate with The motor Mother board is a brain off a three D printer. You can relate this to Mother Border for computer that controls various functions of the machine. On is a complex combination of hardware and former. The board is a combination off ramps 1.4, which is a shield, Or do we know Mega 2560 which is a popular microcontroller on the 49 W drivers ramps? One point for is an open source shield of the Reply project, which is the short form for Alden Omega Pollux Shield. This piece of hardware runs in a form they're called Marlin in an already know i D compiling environment for the mainframe, the haves that access supports on the acrylic body, laser cut parts that holds up the printer together on Finally, we have some buyers for virus Hotbed motors and stops, X Trudeau and parts supply to the mother board 4. Assembly tutorial: 5. Wiring & connections: Hi. Welcome back. First, let's organize all the virus neatly using a cable spiral wrap. We will redirect the cable such that it doesn't interfere with the motion of the excluder or the heart, but on gives our printer a clean look. In this section, we will learn the basic wiring off this three D print of it just assembled. Be careful in the step. Don't plug the power plug in the socket until you have completed the vying. Always double check your connections and make sure the polarity is correct. Well, stop with the bar supply. The power cable, which connects to a wall socket, has three cables life neutral on ground color, coded as brown, blue and yellow, respectively. This goes to the left treatments in the par supply. This is very the park able feeds in a 20 world is ignorant. Military and negative terminals in the last three are positive terminals, which are outputs. They can supply an output off 12 volt and 15 arms to the mother board region. Don barbers the motor hard bed and stops on the north. Now let's have a look at the motherboards wiring. This black plug is for LCD these three white plugs adjust into, they'll see deepen our foreign stops X and stop wine, stop and said and stop, respectively. Next, we have the hot Better Mr and Excluded or Mr Plugs. A Term Mr is a specific type of resistor that uses sensors to help regulate gold on. He'd think off it as a temperature sensor that helps manage the temperature of heartburn on extruded Horton. Here we have the power input boot. You received the power off 12 old from the bar supply modern day care of the polarity here . Next, we have power out blood for X Trudeau on the power block for the hardware. The next two ports are for two fans. Final five plugs are for motors X axis motor y axis motor, the tools that access motors. Andi extrude a motor in this order. We also have an SD card slot, which you can use to print without having to connect your laptop during an entire print on the USB cable slot that you can use for both printing or a former update. And that's pretty much it. They're done fighting on three different Oh, next, we will look into a printer calibration slicing software on, then went to test model
