INTRODUCCIÓN
Welcome to the fascinating world of 3D printing—the technology that’s bringing dreams to life right before our eyes! 3D printing provides the opportunity to create anything you imagine: from artistic designs and kitchen utensils to complex machine parts. This beginner-friendly guide will provide a step-by-step journey through everything you need to know to get started in 3D printing. So, let’s embark on this exciting journey together.
WHAT IS 3D PRINTING?
Often referred to as additive manufacturing, 3D printing is a process of creating tangible, three-dimensional objects from a digital model. This transformation is achieved layer by layer, similar to building a brick wall. This technology was invented in the 1980s, but in recent years it has become much more accessible to the general public, thanks to the emergence of cost-effective, desktop-sized models. 3D printing’s usefulness and adaptability make it a beneficial tool to a variety of sectors, including healthcare, education, manufacturing, and even at-home DIY.
CÓMO FUNCIONA O CÓMO EMPEZAR
To get started with 3D printing, you will need a digital 3D model, 3D printer, and printing material. The steps typically followed are:
1. DESIGN: Create a digital blueprint of the object you want to print using a 3D modeling software. Alternatively, ready-made models can be downloaded from websites like Thingiverse or GrabCAD.
2. PREPARE: The digital blueprint is then processed by ‘slicing software’ which converts the model into thin layers – or ‘slices’. Each slice is then translated into machine-readable instructions for the 3D printer.
3. PRINT: The 3D printer reads the instructions and deposits material layer by layer to construct the object. This process can take anywhere from minutes to days, depending on the complexity and size of the model.
4. FINISH: Once the printing is complete, you may want to do some post-processing practices such as removing supports, sanding, painting, etc.
WHAT YOU NEED TO PRINT
To start with 3D printing, you primarily require three things:
1. 3D Printer: Based on your budget and requirements, there are several models available in the market. Popular choices for beginners include the Ender 3, Prusa i3, and MakerBot Replicator Mini.
2. Modeling Software: These are programs that allow you to design your 3D models. Tinkercad and Blender are both free and beginner-friendly softwares.
3. Printing Material: Filament is the most commonly used material, particularly PLA and ABS. Other materials like resins are used in different types of 3D printers.
TIPS FOR ABSOLUTE BEGINNERS
1. START SIMPLE: Begin with simple models that are easily available online before progressing to designing your own.
2. PATIENCE: 3D printing is often a trial-and-error process. Be prepared for imperfect prints and use them as learning opportunities.
3. MAINTENANCE: Regularly clean your printer and change filament as needed.
4. SAFETY: Always have supervision when the machine is running, especially when using printers that utilize high heat.
5. COMMUNITY: Join online communities of fellow 3D printing enthusiasts for advice and inspiration.
RECURSOS ÚTILES
• Thingiverse: A database of millions of 3D printing models.
• Tinkercad: A basic, free 3D modeling software.
• Ultimaker Forums and Reddit’s 3Dprinting subreddit: These communities offer advice and share experiences regarding 3D printing.
GLOSARIO: EXPLICACIÓN DE TÉRMINOS COMUNES
1. BUILD PLATE: The surface upon which the 3D printer makes the object.
2. EXTRUDER: The part of the printer that pushes filament into the hot end to be melted and deposited.
3. INFILL: The interior structure of a 3D print. Usually not solid to save time and material.
4. LAYER HEIGHT: Measurement impacting print quality and speed. Smaller values result in higher resolution but slower printing.
5. SUPPORTS: Temporary structures printed to help overhangs during the print, these are subsequently removed.
