Abstract: This project represents the design, construction and development of 3Dprinter. According to the study of comparing traditional manufacturing methods for producing components, organic methods are implemented. The idea of this project is entirely based on controlling the motor for full steering across each axis. This Project utilizes ARDUINO MEGA to control the entire circuitry.
The first step in 3D printing is to design a digital 3D model. It is nothing but a process of developing a mathematical representation of any surface of an object in three dimensions via specialized software. Here we are using CAD (computer-aided design) tool to develop such a model. Design slicing: design slicing is the process where the 3d model will slicing vertically into many layers so that the printing process will be easier. Printing of these components will be done layer by layer from the bottom. In the case of Laser Engraving, we are creating a 2D image as we are doing Engraving on a flat surface. This 3D model or 2D image will be converted into G Code using software GIMP, which is open-source software. In this model, we have used the Arduino UNO controller. Using GIMP software, we will give Gcode to the Arduino controller. Then we have used GRBL firmware for Arduino Controller that controls stepper motor. GRBL uses G-Code as input and outputs signals via the Arduino pins, which will give a command to stepper motor driver LM317. That will generate required pulses for the movement of stepper motor. This is how we can control our axis and create a 3D model in case of 3Dprinter or we can create required image on surface using Laser Engraving. 4. Analysis and Results
Once completed, the STL file needs to be processed by a piece of software called a "slicer," which converts the model into a series of thin layers and produces a G-code file containing instructions tailored to a specific type of 3Dprinter (FDM printers). This G-code file can then be printed with 3D printing client software (which loads the G-code, and uses it to instruct the 3Dprinter during the 3D printing process).
To ensure faster progress on the improvement of 3D printing technology, open source platform such as RepRap is the one with low cost of investment needed compared to others. There are various model of open source for low cost 3Dprinter. One of it is Prusa. 3D printing is a technology with high potential to be cost effective with the production while keeping the waste material at low volume compared to conventional method (Lindemann and Reiher, 2015).
To ensure faster progress on the improvement of 3D printing technology, open source platform such as RepRap is the one with low cost of investment needed compared to others. RepRap are the most commonly used 3-D printers (Moilanen & Vadén, 2012). There are various model of open source for low cost 3Dprinter such as Prusa i3 and delta. To considerably abbreviate the ideal opportunity for creating patterns, molds, and models, some manufacturing ventures have begun to utilize fast prototyping strategies for complex patterns making and factor prototyping (Yan & Gu, 1996).
3D printing also listed as a quick production as compared to practical method where it is more sustain and eco-friendly machine. Similar to other devices or machines, they also lead on same direction and goal but in different speed and time travel also differs significantly. Nowadays, 3Dprinter machine and its technology are able to create an object with several of shape in few hours. This leads supplier to be on-demand manufacturing for modeling and may be reconsider about costing before the real line manufacturing.

Welnu, in deze omgeving ga ik aan de slag met mijn Bachelor Eindopdracht. Voor mij staat een deels transparant bouwwerk onder de noemer ‘Open Source 3D-printer’. Er hangen draden aan, in alle kleuren van de regenboog. De wieltjes en assen aan de bovenkant doen vermoeden dat er dingen gaan bewegen. Het grauw uitgeslagen plexiglas verraad het ontbreken van een belangrijk element: poeder. Met behulp van dit poeder, de wieltjes en assen, de gekleurde draden en alle andere onderdelen waarvan mij de functie nog niet duidelijk is kan deze machine voorwerpen printen. Driedimensionale voorwerpen, die je kunt zien, vast houden, ruiken en proeven. Binnen mijn onderzoek zal de nadruk niet op de laatste twee liggen.
The purpose of this project is to make a design improvement on support system for resin based 3Dprinter. The basic concept of rapid prototyping must be understand first. Then, support system for resin based 3Dprinter was studied. By using 3Dprinter, 3D object can be created by layering a material (plaster, cornstarch, resins) and it consist of an inkjet layering printing system. 3D object can be created with a short time compared to the other method. To examine the problem on support system, the main cause was investigated and step to avoid this problem from occurred again will be done by doing a design improvement on the machine. Some improvement on the support system for resin based 3D machine is needed to make sure that this machine can perform it task with efficient and perfectly. By doing this research this problem can be solved.
Abstract: Control as a Service (CaaS) is an emerging paradigm where low-level control of a device is moved from a local controller to the Cloud, and provided to the device as an on-demand service. Among its many benefits, CaaS gives the device access to advanced control algorithms which may not be executable on a local controller due to computational limitations. As a step toward 3Dprinter CaaS, this paper demonstrates the control of a 3Dprinter by streaming low-level stepper motor commands (as opposed to high-level G-codes) directly from the Cloud to the printer. The printer is located at the University of Michigan, Ann Arbor, while its stepper motor commands are calculated using an advanced motion control algorithm running on Google Cloud computers in South Carolina and Australia. The stepper motor commands are sent over the Internet using the user datagram protocol (UDP) and buffered to mitigate transmission delays; checks are included to ensure accuracy and completeness of the transmitted data. All but one part printed using the cloud-based controller in both locations were hitch free (i.e., no pauses due to excessive transmission delays). Moreover, using the cloud-based controller, the parts printed up to 54% faster than using a standard local controller, without loss of accuracy.
A 3dprinter can have a lot of different uses. Some have are making toys, chip clips, tweezers, hair combs, and phone cases. Usually 3d printing is more for business. When used for business 3d printing can be extremely useful. Like in medicine, doctors can use 3d printing to print bones and organs from patients’ cells. Other businesses 3d printing can be used are General Electric, Boeing, Ford, and Nike.With 3d printing engineers can create jigs, tools, and fixtures. (David, 2019). 3d printing is ideal for creating molds.
higher-resolution subtractive process can achieve greater precision some printable polymers such as ABS, allow the surface finish to be smoothed and improved using 3Dprinter based on similar. Some additive manufacturing techniques are capable of using multiple materials in the course of constructing parts.
discussed the different types of materials that can be used for 3Dprinter applications and their properties of the material based on melting temperature and solidifying temperature. Meera Mohan et al (2017), in this project they have researched and studied about the different types of temperatures sensors that can be used in different applications to measure the desired temperatures. Seyeon Hwang et al (2015), in this project he had studied and analyzed about the different types of materials that can be used in the filament extrusion process and also their different mechanical properties that has to be consider while selecting a filament. Adhiyamaan and S.H.Masood (2014), have presented a study of dynamic and mechanical properties of fused deposition Modelling (FDM) on rapid prototyping processed material such as acrylonitrile butadiene styrene. It involves the measurement of damping properties of the material as it is deformed under stress. Lihan Huang and Joseph Sites (2007), proposed a paper of automatic control of microwave heating process for n package pasteurizing of beef frankfurters which helps used how to control the temperature for the process.
The purpose of this research is to investigate the suitability of the plastic packaging or bottle into 3Dprinter filaments and create the 3D filament. High density polyethylene (HDPE) is characterize as relatively stiff with high tensile strength compare to the other polyethylene based material (American Chemistry Council, 2007). So, the HDPE is the most suitable material to produce filament and it is easy to obtain as this research is conducted by using plastic packaging waste such as plastic bottle. There are many commercial products in market that using HDPE as their plastic packaging.
3D printing is best to visualize as a transformation of virtual 3D model into solid form one layer at a time. By contrast, a 3Dprinter can create an adjustable wrench in a single operation, layer by layer. The torque comes out of the printer completely gathered, counting all its moving parts (Koff and Gustafson 2012). A layer is built on another layer before that can be representing the virtual 3D model including model’s complexity and detail without additional forms of machining required and also a treatment necessary in conventional forms of manufacturing. 3D printing or additive manufacturing is a process of making three dimensional object from a digital file. The creation of a 3D printed object is achieved using additive processes. The idea in additive process is topping a layer before with another layer according to dimension and details of the structure from its digital file. Every one of the layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
 MedhaviKamrana, Abhishek Saxenab- studied Charles W. (Chuck) Hull's first working robotic 3Dprinter in 1984.3D printing has changed the manufacturing industries since late 1980 ' s.In 2009 only the "desktop" 3D printers were came to the public. Later, S.Scott and Lisa Crump has patented the Fused Deposition Modeling (FDM) in 1989.This technology also called FFF(Fused Filament Fabrication).When all companies begin to develop 3D printers, the patents are expired in 2005.Then,this technology became the basis of the RepRap movement.
manufacturing method used for manufacturing of solid Three Dimensional parts. It requires less human efforts and manufacturing time for parts is less. Different parameters such as Layer Thickness, Shell Thickness and Fill Density affect the mechanical properties such as Surface Roughness, Hardness and Tensile Strength of 3D Printed Parts. On this basis, this paper focuses on “Optimization of Process Parameters for 3D Printing Operation on FDM 3DPrinter”. On the basis of optimized parameters the manufacturing time and mechanical properties will be enhanced. It provides proper methodology for optimized 3D Printing. Experimental results are comparable to those for different variations in parameters.
The major advantage of a 3Dprinter is that it allows the designers to produce a prototype in a very short time, which is tested and quickly remodelled and reducing the required time from the prototype phase to obtaining the final product. At the same time, using this technique we can obtain accurate components and also complex parts in shorter duration that, through Cartesian and other methods would take a large amount of time to accomplish it.
With the rising demand of small parts and operations, number of small scale automated machines like CNCs and 3D printers came into the top fabricating work for the industries. The priorities are being given to fabricate those machines in affordable price and size. Here in this paper it has been designed and tried to build a CNC with compatible to 3Dprinter which is very simple and affordable.
3D printing is also known as additive manufacturing which is a process of fabricating 3D objects from digital file that are created from CAD software. In industry field, the additive process is operated by laying down successive layers of thermoplastic materials until the whole object is formed and it results the thin sliced horizontal layers on the surfaces of the object. Moreover, the material used for the 3Dprinter appears to be in the filament form that coiled by a spool and the making of the plastic filament is done by a sustainable filament extruder.
