Design and Developement of a Polar 3D printer
Project Area of Specialization Mechatronics EngineeringProject SummaryA lot of improvement, research and growth has taken place in 3D printing industry over decades. The increasing popularity and utilization of 3D printing technology have resulted in the evolution of 3D printing over the years. Heated printing beds, Bowden Extruders, print bed enclosures – these are just some of the features and fixtures that the 3D printing industry has come up with to create better quality 3D prints.
Cartesian 3D printers operate similar to a CNC machining center, specifically containing the up and down motion of either the print bed or extruder. Another 3D printer configuration is a Delta 3D printer, which has a stationary build platform and uses three motors located on pillars controlling the end-effector location. Involving a circular print bed with a 3D printer extruder featuring three fixed triangular points. Each of these three points can move both upwards and downwards within the cylinder print structure, to be able to place the print head where it needs to be to print.
One of the most drastic and apparent changes that have come to 3D printers comes with the development of Polar 3D printers. This printer is certainly the rarest and still considered an emerging design, but more and more 3D printing professionals are starting to recognize how advantageous it could be. These printer types massively deviated from the design and workflow of the traditional Cartesian and Delta 3D printers. Our main aim is to showcase the potential that a polar 3D printer offers better flexibility, reduced cost, and compact and simple design. In addition, to endorse the open science with the application of improved experimental techniques while discussing its limitations.
Aims and Objectives
The aims and objectives which we aim to do in this project are:
• To design a portable Polar 3D printer.
• To maintain the printing quality.
• To make 3D printer speed adjustable reducing the chances of jerk and printing failure.
• To automate and control the temperature of the extruder.
• To improve and specify the movement of extruder and base relative to each other.
In the field of 3D printing, Polar 3D printers are particularly unusual, not only because of their different look but because they use a completely different coordinate system. The overall structure of a Polar 3D printer also differs from the other 3D printers because generally, these printers are boxy, but for the Polar 3D printers, the structure is L- shaped. A Polar 3D printer consists of a circular-moving baseplate about a Theta axis, a print head or extruder moving radially (about R-axis) and vertically (about Z-axis), hence providing a faster and smooth printing method. Some 3D printers buck this trend by designing the print head to move only in a vertical direction and the print bed moving along the theta and radial axis but this idea is comparatively slow.
Furthermore, in between the final product and 3D printing, there is a G-code present, which plays the role of a bridge. The G-code converts STL or SLA format files to any language that is being used for coding and then the coding is translated by the processor, which in turn commands the actuators to move and print the desired object.
3D printers come up with various designs and numerous printing methods. Common Cartesian 3D printers are unable to provide fast printing (due to inertia) with a compact working setup. As mentioned in the introduction earlier, our project aims to make an FDM-type Polar 3D printer. These types of printers, unlike the Cartesian ones, provide faster printing with reduced production cost and time. Such printers are rare and unique. This 3D printer targets the market requiring the production of circular elements on smaller footprints with less hassle of physical setup. Despite its smaller footprints, it also allows for comparatively larger prints.
Technical Details of Final DeliverableThe main problem with the typical Cartesian 3D printers is that these printers are quite bulky and difficult to carry around. Furthermore, the issue related to the printer is the jerk that can lead to inaccurate deposition, and even the printing in some cases fails. Along with this, an increase and decrease in speed cause a reduction in the quality of the final product. Polar 3D printers do not require bulky and heavy frames, which minimizes the jerk problem. In addition to this, polar 3D printers provide fast printing with efficient power consumption.
