5 things you need to know before buy a 3d printing machine
So you want to buy a 3D printing machine for your home but have no clue about which one is the best for you? Before buying a desktop 3D printer there are several things you need to know in order to get the one that best fits your needs. Our suggestions is: always search for the specification details for every machine and don’t be tricked with some things that mightmake you choose incorrectly. Afterall, no matter what you want to do with the printer, it always requires a great investment, isn’t it? So here’s our tips for you to choose wisely.
1. Price can be tricky
3D printers price is not a new topic on this blog because it is truly really important. The budget you have to spend in a 3D printer may change everything that will come next. And that’s not the only thing: when you’re in the search to buy a 3D printing machine, you may be tempted to go for the cheapest ones but be careful – sometimes a little more effort here may be a life saviour later! And don’t be so mesmerized with the most expensive ones because it doesn’t mean that they are the best. Check out our comparison between some of the best current 3D printers on the market.
2. The build volume is crucial
Unless you want to print chair for ants, a good build volume is really important on a desktop 3D printer. It would be a really bad thing if you go and buy a 3D printing machine and then oooops! – you can’t use it for your projects. Our CraftBot has one of the biggest build volume in its class (250x200x200 mm, approx. 10x8x8 in) so why not give it a try?
3. Most cheap 3D printers don’t use a heatable build platform
A heatable build platform requires a stronger power supply and that’s why most of the lower-priced 3D printers don’t use it. If you are new to this area, when you buy a 3D printing machine you may even think that this is only an additional feature and that’s ok if you don’t have a heatable build platform but that’s wrong. 3D printing material shrinks as it cools down, therefore 3D printed objects tends to bend or warp during the printing process, causing the printer head to collide with the object, ultimately ruining the print. And that’s why a good 3D printer MUST have one.
4. Consistency of Print
3D printers regularly print at layer heights of 100-micron, so if there’s warping in the build platform of more than 100-micron, the first layer isn’t going to stick well in different places. In this case, when you buy a 3D printing machine, don’t be tricked: smaller minimum layer height is better in order to get a better printing resolution.
5. Don’t be tricked by proprietary filament
PLA is probably the best non-toxic material to get you started with 3D printing and gives you the freedom to choose the one that best fits your budget. Before buy a 3D printing machine beware: some companies use proprietary filament which is significantly more expensive! Proprietary filament is a custom filament which must be used to fit a specific machine. Don’t be tricked, they are designed to create another source of income for the company.
