This technology allows for the construction of complex shapes and designs, and modular products to create bigger items, which would be almost impossible to do at home, with traditional manufacturing methods.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">3D printing is allowing start-up businesses to produce prototype products, transforming industries such as automotive, medical or fashion, at easily achievable budgets.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Understanding how 3D printers work is no longer the realm of tech enthusiasts or engineers. It\u2019s becoming more and more an at-home appliance for hobbyists and small businesses. With this blog, you\u2019ll grasp the basics and find a way to unleash your creativity. 3D printing offers a world of possibilities, where you can solve real-world problems, create customized products, and so much more.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Understanding 3D printing is a skill worth investing your time and energy into. Let\u2019s get exploring the world of <\/span><a href=\"https:\/\/www.inkstation.com.au\/3d-printing\/printers\"><span style=\"font-weight: 400;\">3D printing with Ink Station<\/span><\/a><span style=\"font-weight: 400;\">!<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2 id=\"what-is-3d-printing\"><span style=\"font-weight: 900;\">What is 3D Printing?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">3D printing is a process of creating a three-dimensional object by adding material, layer by layer for a filament printer, or through curing material with a UV light in the resin printing process. Objects are produced from a digital design.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Computer-aided Design (CAD) software allows people to create complex objects directly from a computer to the printer, often in the same room or facility. Incredibly convenient.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The journey of 3D printing began in the 1980s\u2019. The first patent related to this technology was filed by Dr Hideo Kodama of Japan in 1980, but it was Chuck Hull in the USA, in 1986, who first successfully patented a commercial 3D printing process called stereolithography (SLA), and the creator of the widely used STL file format for modern 3D printing.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Today, 3D printing is pushing the boundaries of many industries, such as medical technology, aerospace engineering, bio-engineering and more. It is opening doors for smaller businesses to compete on a level playing field with big manufacturers, and it\u2019s helping at-home hobbyists and artists realize their creative dreams.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2 id=\"basics-of-3d-printers\"><span style=\"font-weight: 900;\">The Basics of How 3D Printers Work<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Let\u2019s begin by looking at the core ideas of what 3D printing is, and the different types of 3D printing.\u00a0<\/span><\/p>\n<h3 id=\"types-of-3d-printing-technologies\"><span style=\"font-weight: 800;\">Types of 3D printing technologies<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\"><b>Fused Deposition Modeling (FDM)<\/b><span style=\"font-weight: 400;\"> &#8211; This is an additive manufacturing process, where an object is built layer by layer through selectively depositing melted material on the build platform in a predetermined path. <\/span><span style=\"font-weight: 400;\">It is the most widely used 3D printing type around the world and is the most common filament printing style.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"3\"><b>Stereolithography (SLA)<\/b><span style=\"font-weight: 400;\"> &#8211; this is the most common form of resin printing. It is growing in popularity for its ability to produce fine quality prints with a high level of accuracy and a smoother surface finish. <\/span><span style=\"font-weight: 400;\">A light source, either a laser or a projector, is used to cure a liquid resin into a hardened plastic. Resin printers can be toxic, so safety standards must be followed both during and post-print.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"3\"><b>Selective Laser Sintering (SLS)<\/b><span style=\"font-weight: 400;\">&#8211; this is a 3D printing process where a high-powered laser is used to sinter (bind) a specific fine powder into a solid structure. <\/span>A printer will lay down a layer of fine powder, and the laser is used to precisely bind that powder to the specifics of the digital file.<\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">3D modelling software is a key ingredient in the 3D printing process. It is where a 3D object is created, which is then printed and realised.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Computer-aided Design (CAD) programs allow users to create highly detailed 3D objects. These are saved as STL files, instructions for the 3D printers to produce the object.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The #D software is the bridge between the ideas of a creator and the fully realized final product.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2 id=\"key-components\"><span style=\"font-weight: 900;\">Key Components of a 3D Printer<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">What is a 3D printer, and what are the key components involved?<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The 3D printer frame and structure<\/b><span style=\"font-weight: 400;\"> &#8211; A sturdy frame and physical foundation of a 3D printer, the frame provides stability for the printing components. Made from metal or very rigid plastic, it helps minimize vibrations during printing, allowing for precision. <\/span><span style=\"font-weight: 400;\">The frame houses the print bed, the extruders and nozzles, and the movement mechanics, allowing for movement and printing in all 3 axes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The printing bed: features and importance <\/b><span style=\"font-weight: 400;\">&#8211; The printing bed is where a 3D object is produced, where layers of filament, or treated resin, are laid down to create an object. <\/span>A print bed needs to be adhesive to hold the object during printing, but not so grippy that you cannot remove the finished item easily. They also have to be level. A stable and level print bed is vital in producing a high-quality and accurate print.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Extruders and nozzles: their roles in printing<\/b><span style=\"font-weight: 400;\"> &#8211; Extruders and nozzles are what deliver the materials to the print bed, which get turned into the final 3D printer product. <\/span>The extruder heats the filament and pushes it through the nozzle to be layered up for printing. The finer the nozzle, the finer the printed product, but the slower the print.<\/li>\n<\/ul>\n<h3 id=\"filament-types\"><span style=\"font-weight: 800;\">\u00a0Filament types and their uses<\/span><\/h3>\n<p><a href=\"https:\/\/www.inkstation.com.au\/3d-printing\/filaments\"><span style=\"font-weight: 400;\">There are 3 main types of filaments used in 3D printers<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>PLA (Polylactic Acid) <\/b><span style=\"font-weight: 400;\">&#8211; PLA is made from renewable sources such as corn starch or sugar cane. These filaments are produced in the same ways as other types of filaments, so the quality of print doesn&#8217;t suffer. <\/span><span style=\"font-weight: 400;\">PLA can be used to print medical supplies and foodstuffs. It works at lower temperatures, so there is no need for a heated print bed, and it has no foul odors associated with its use. <\/span><span style=\"font-weight: 400;\">PLA is biodegradable, breaking down between 18 months and 2 years. This is why it is perfect for medical applications, disposable clothing, disposable eating utensils and more.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>ABS (Acrylonitrile Butadiene Styrene)<\/b><span style=\"font-weight: 400;\"> &#8211; a robust thermoplastic polymer, it is widely used in 3D printing and has properties such as high strength and durability and high heat resistance. <\/span>Due to its durability, ABS 3D printing is often used to create mechanical components and prototypes, however, it needs a heated printer bed to prevent warping.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>PETG (Polyethylene Terephthalate Glycol) <\/b><span style=\"font-weight: 400;\">&#8211; This is a polyester variant that blends the ease of PLA and the strength of ABS. <\/span>It is impact-resistant upon printing and is very resistant to moisture. It is used to create everyday products as well as some 3D-printed jewelry.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2 id=\"3d-printing-process\"><span style=\"font-weight: 900;\">\u00a0The 3D Printing Process Explained<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">How does a 3D printer work? There are 4 key steps in the 3D printing process.<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Preparing the design<\/b><span style=\"font-weight: 400;\"> &#8211; This is where the idea first emerges, the concept of what you want to print. You design the model in a 3D modelling software package. The better the 3D model, the better the end product, so a good amount of time is required to ensure the model is functional and printable.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Slicing the model<\/b><span style=\"font-weight: 400;\"> &#8211; When your model is ready, you upload the 3D model into slicing software. This converts the model into thin slices, or layers, for the printer to produce. The software and the printer sync, so the software can take into account layer height, printing speed, temperatures and more.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Printing the model<\/b><span style=\"font-weight: 400;\"> &#8211; When the sliced model is uploaded (The G Code), the printer begins its process of layering the filaments or hitting resin with UV light. It produces the item onto the print bed and can take some time to fully produce a 3D-printed object.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Post-printing<\/b><span style=\"font-weight: 400;\"> &#8211; There may be some post-printing processing before you can take the model out to show the world. It can be washing the item, or treating it with UV light, sanding rough surfaces or sealing any holes or gaps in the model.<\/span><\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<h2 id=\"applications-of-3d-printing\"><span style=\"font-weight: 900;\">Applications of 3D Printing<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">How and where you can use 3D printing is already incredible, and the potential is only growing larger and further.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Industrial manufacturing <\/b><span style=\"font-weight: 400;\">&#8211; You can create cost-effective replacement 3D printed parts, or custom-built parts for a wide range of industrial uses.
