Two 3D Printers You Can Make Yourself For Around $1,000

Last time I gave a theoretical introduction to 3D printers Ultimate Beginner's Guide to 3D Printing 3D printing was supposed to be the new "Industrial Revolution." It hasn't taken over the world yet, but I'm here to talk you through everything you need to know to get started. Read More and talked briefly about some concepts such as self replication and the effect such devices would have on society. Today I’d like to show you two specific projects that can built for more or less $1,000, both of which are fully functional 3D-plastic printers, and both of which are open-sourced and actively being developed.


Make no mistake, these are set to be the next big thing and will change the world as we know it. I’ll also briefly cover a site where you can download models to make once you’ve built your 3D printer The Best 3D Printers Under $500 in 2019 Are you after an affordable 3D printer? Here are the best 3D printers under $500 to help you find the best one for your needs. Read More !


MakerBot is the first well-publicised DIY 3D printer and as such has had a good amount of time to mature. Last week, they even raised $10 million in Venture Capital, so you can be damn sure this one is on the right track.

To give you an overview of the machine better than I could ever hope to explain it in text, here’s the Make-man himself Bre Pettis talking about the MakerBot.

Note: The latest version is the Thing-O-Matic, but the model seen in the video is the “Cupcake CNC 3D Printer”.

The Thing-O-Matic (seen below) is also now able to continuously print objects by “ejecting” them once finished. So that actually means you can have your own private factory line. Above all, just look at it – it’s so incredibly cute, wouldn’t you want one in your workshop?

As for self-replication, the MakerBot is somewhat limited by its build area (the physical dimensions of the largest object that can be printed) of 10cm, but one enterprising young fellow achieved it by gluing many of the parts together. Those looking for a larger build area should look no further than the RepRap.


The RepRap is a more DIY effort that has a larger build area of 20cm, but requires a lot more tweaking and calibration. It’s also not quite as cute, but easier to repair and upgrade – apparently – and users claim you will learn a lot more in the process of building one.

While you can purchase the complete ready-made kit from BitsFromBytes for between £800-£1,200, the RepRaps are designed from the ground up to be self-replicating at a current rate of 50%. That means each RepRap can make 50% of the parts required to make another RepRap, which is quite mind blowing.

This was first achieved back in 2008. Future versions of the RepRap printer will of course be able to be printed by the current version(!), and hopes to raise the percentage of self-replicability even further.


From the Make-crew, the Thingiverse is a community open-source repository for digital 3D object designs, as well as a social network for people who actually design or make them. Some of the things you can download and print on your own 3D printer understandably range from the absolutely ridiculous – a Mentos Diet Coke cannon; insanely awesome – a life-size replica of the Thundercats Sword of Omens; to the frankly quite useful – drawer dividers. You can find them all in the “popular” archives.

Really though, it’s perhaps time to stand back, take a breath, and just try to comprehend how unbelievably cool this all is – you can download and print a physical object. This, dear readers, is the future – but it’s also here right now. Learn more about 3D printing by reading our complete beginner’s guide to 3D printing Ultimate Beginner's Guide to 3D Printing 3D printing was supposed to be the new "Industrial Revolution."

    Thingiverse is probably a small previe of the sites were we will dowload our objects in a few years.

    I don't think many people realise how much of a massive step this is, and how it is going to change printing forever. As you say, it is unbelievably cool that you can now print a physical object! Do the makerbot printers also colour the objects? Or just print them in the hard form and you colour them yourselves.

      No colour yet unfortunately, though you can change the plastic spool that feeds into it - so theoretically if you could separate the object into the separate colours and print them individually then, yes. I expect they'll have multihead printing for different colours in another year or so though, which will then just be a simple upgrade...

        Thanks for the reply Bruce. When colour becomes available, 3D printers will become a very, very big deal!

        I have just had a look on the Makerbot site and you can now do two colours on your models. They have a screencast about it if you want to find out more.

          Here's the link, for anyone interested.

          Awesome, by the way.
