I\u2019ve been making 3d prints for a while, but, I thought I\u2019d answer a quick question new people have when they\u2019re first thinking about getting a 3d printer. Which is, what specs do I need on my computer to use a 3d printer and make or print 3d print designs. Based on my research and experience here\u2019s what I found.\n\n\n\nSo, what computer do you need for a 3d printer? Cura is the most popular software for sending 3d prints to your 3d printer. The minimum system requirements for it are:\n\n\n\nOpenGL 2 compatible graphics card, OpenGL 4.1 for 3D layer viewIntel Core 2 or AMD Athlon 64550 MB available hard disk space4GB RAM memory\n\n\n\n\n\n\n\nYour 3d printer itself doesn\u2019t need to be connected to your computer to run. But, you do need a computer to load the 3d print designs onto it. This software that does that is called a slicer.\n\n\n\nYou can also use 3d design software to make designs. Fusion 360 and Tinkercad are the most popular programs for designing your own 3d prints and it runs in your web browser like Google Chrome, or Safari. And needs the same computer as the slicing software, or even less. That said, if you want to run professional CAD software, like AutoCAD, you will need a much more powerful computer.\n\n\n\nBelow, I\u2019ll explain how much a computer that has these specs costs - hint it\u2019s very cheap, how to check the specifications of your current computer, and whether 3d printing is hard to learn.\n\n\n\nDo You Need a Good Computer to 3D Print?\n\n\n\nA computer that you need to do 3d printing does not need to be good at all. You can use a fairly old computer. The technology for the minimum specifications to 3d print:\n\n\n\nGraphics card \u2013 typically anything manufactured after 2012Processor \u2013 anything that supports the latest OSRam - Most PCs have 2GB+, it\u2019s very cheap to get more\n\n\n\nTherefore, if your computer is less than around 8 years old, it will be good enough to use for designing 3d prints. To put it in perspective the iPhone 5 came out in 2012. Which is the same year that the graphics card that you\u2019ll need was invented.\n\n\n\nSo, you can use a fairly old laptop, which costs around $150 to $200 second hand. You can\u2019t buy them now because they don\u2019t make them anymore. \n\n\n\n\n\n\n\nHowever, it\u2019s good to double check any computer or laptop you buy with the minimum requirements above.\n\n\n\nYou can see the specifications for any computer before you buy it, and people who sell computers will always list the specs for the computers they\u2019re selling. \n\n\n\nIf you get a computer that has higher specifications then the ones I listed above, then it will be faster. And it will be better. However, it isn\u2019t required.\n\n\n\nWhat Is Required for 3D Printing?\n\n\n\nFor 3d printing you need:\n\n\n\nA 3d printer \u2013 Like the Ender 3 from AmazonFilament - most 3d printers come with some, but the quality isn\u2019t always the bestA computer - to transfer the design to your 3d printerVarious free software - to create or prepare files for your 3d printer\n\n\n\n*The Amazon links in this article are to products I personally use. \n\n\n\nDo 3D Printers Come With Design Software?\n\n\n\n3D printers don\u2019t come with design software but you can get all the software you\u2019ll need for it for free. You\u2019ll need what\u2019s called a slicer, which will process the design files so that your 3d printer can understand it. The most popular slicer today is Cura. And you\u2019ll need software to design a 3d print. \n\n\n\n\n\n\n\nYou can also download a tone of free 3d print designs for all sorts of things you need around the house, or cool things you want to make for fun. A good website to find a tone of free designs is Thingiverse.com.\n\n\n\nThey have everything from key holders to dinosaurs. And everything in between. You\u2019ll be surprised what\u2019s on there. You can download the complete design in a few clicks, and they\u2019re absolutely free.\n\n\n\nThe software you need to 3d print is of two types 1) software to create designs 2) software to slice the design.\n\n\n\nTo design your own prints it does take a bit of time to learn and practice. A good place to start is with TinkerCad.com which is completely free. And has a bunch of lessons. It\u2019s designed for children, but you can create some incredible designs with it, and the sky\u2019s the limit. \n\n\n\nYou could honestly use this program for all of your 3d printing and be fine. But there is also harder software that has a much steeper learning curve, and you\u2019ll need to spend a lot of time learning them. These are software like Onshape or Fusion 360. However, these programs are much more expensive and the cheapest versions cost around $40 a month. You can sign up for a hobbyist account for personal use with Fusion 360 here. But, 3d modeling software changes a lot. So, it might not be free when you read this.\n\n\n\n3D Sculpting\n\n\n\nThere\u2019s two broad types of 3d printing design software - those for designing geometric type 3d designs, and sculpture type 3d designs. \n\n\n\nFor example, you would use the first type if you\u2019re designing a pen holder, and use a sculpting type of 3d software for designing a dinosaur. A good free software for making sculpture 3d models is Blender. And you can find playlists on Youtube which will teach you how to use it. \n\n\n\nBut, with this program some of your designs might not be printable with a 3d printer. So you\u2019ll need to know your stuff.\n\n\n\nIs 3D Printing Hard to Learn?\n\n\n\nGetting your 3D printer up and running and printing with it isn\u2019t hard to learn. But, creating your own designs is difficult and more complicated software can take a LONG time to learn. Using a more complicated software like Fusion 360 will take a lot of time to figure out and use.\n\n\n\nThe main reason is there are so many different features and options when you use the more complicated software. Because of that you have to sift through a lot of different options to find what you\u2019re looking for and it\u2019s hard to know where to start.\n\n\n\nOver time you will become familiar with it and can move quite quickly when you\u2019re designing something. But, in the beginning it is overwhelming.\n\n\n\nHowever, you can get all set up and do your first prints in 6 hours or so. For example:\n\n\n\nUnboxing your 3d printerSetting it upInstalling the softwareDownloading a printPrinting it\n\n\n\nWhat Is the Easiest 3D Software to Learn?\n\n\n\nThe easiest 3d printing software to learn is TinkerCad. The user interface is very easy to navigate, it has a bunch of lessons that cover the basic concepts of creating 3d print designs, and is designed for kids. This means it\u2019s very user friendly for adults as well.\n\n\n\nOnce, you have a handle on the basic ideas behind creating a 3d design, you can use more complicated software like Fusion 360 or Onshape. \n\n\n\nThese software are used by professionals who do 3d design for a job. These people are employed by electronics companies, architects\/construction, and engineers.\n\n\n\nHow Long Does It Take to Print Something on a 3D Printer?\n\n\n\nA small 3d print takes about 30 minutes. But, you can print very large and intricate things which can take as long as 7 days. A hobbyist 3d printer will typically make prints that take less than 6 hours. The size and intricacy of what you print determines how long it will take.\n\n\n\nIf a 3d print design has lots of fine detail, the arm of the 3d printer will need to go back and forward a lot. For example, it will drop a small amount of resin in one spot then move to the next spot, and drop a small amount of resin. Which adds a lot of time to the print.\n\n\n\nBut, if it\u2019s a solid object, it will go back and forward in a small area and won\u2019t take as long.\n\n\n\nRelated Questions\n\n\n\nWhere else can I get STL files from? \u2013 There are many other sites that have STLs available. Some sites offer them for free and others charge for them. Here are four alternatives to Thingiverse.\n\n\n\nMyMiniFactoryPrusaCults 3DPinshape\n\n\n\nWhat is a good starter 3d Printer? \u2013 I personally like the Ender 3 Pro or the Ender 3 V2, both available on Amazon. Both are available for under $300 and have a great community around them with people willing to help out if you run into issues.\n\n\n\n\n\n\n\nRelated Articles\n\n\n\nHow to Print a File from Thingiverse (The Easy Way!)Create a Temperature Tower Using Cura - The Easy WayCura ProfilesDo 3D Printers Use a Lot of Power? (The Numbers Inside)\n\n\n\nRecap\n\n\n\nHere\u2019s a brief summary of everything I covered in this article as a refresher:\n\n\n\nYou do not need an expensive computer to do 3d printing. It can be an old laptop that costs around $150 to $200. The software that you use to design 3d prints is mostly cloud-based. And you access it through your web browsers, such as Google Chrome or Safari. Because of that, it doesn\u2019t do any processing on your computer, and so your computer doesn\u2019t require a powerful processor or graphics card. \n\n\n\nMake sure you check out our YouTube channel, and if you would like any additional details or have any questions, please leave a comment below or join us on Discord.
