Freecad 3d printing checker12/28/2023 You know, a big Benchy, printed with thick layers and a smooth, matte finish, looks great. Don’t change its geometry, and especially don’t scale it up or down. If a profile has issues as-is with printing a 3DBenchy, those issues are going to show up in some other print at some point, too.Īnd secondly, also print the Benchy as-is. First of all, I think this should be obvious, don’t use any special profiles or settings for it, print it the exact same way you would print other parts as well. But nowadays what you can expect from 3D printers is a lot better than what you could then, and honestly, if an off-the-shelf machine can’t print a near flawless 3DBenchy straight out of the box, I’m going to have to assume the manufacturer is either lazy or incompetent, or both, or the machine is broken.īefore we go over all the things to look for on a Benchy, let’s briefly touch on how to print one. When the Benchy first came out, it was an actual benchmark test, you could clearly see the differences between printers. Very rarely are you going to work with parts that are not in some way optimized for 3D printing.īut this is also becoming a bit of an issue for the Benchy as a “torture test”. I’ve made some test parts in the past that really hone in on some specific details, but what the Benchy does is to be realistic – there are no crazy long bridges, there are no details that are smaller than your nozzle, there are no crazy overhangs, and that is sort of what your typical 3D print is going to look like, too. Because the 3DBenchy has such a wide range of feature sizes, geometries, and details, you’re always inadvertently also checking for all of those areas where you might have made something worse.īut the 3DBenchy isn’t a benchmark for benchmarking’s sake. When you’re making changes to your printer’s setup, it is super easy to over-optimize for one single thing, because most settings you have access to affect a multitude of aspects of your prints, some aspects you’re going to improve, and others you are often going to make worse, for example, as you increase temperature, within reason, you’re going to get stronger parts, but you’re also going to get droopier bridges, more stringing, and worse top surfaces.Īs you increase jerk and acceleration, you’re going to get rid of ridges on round features, but you’re also introducing ringing and extruder control issues to your prints. What I find most important is that it doesn’t just cover a single tuning parameter. What makes the 3DBenchy such a great testing model is quite a few things actually. It is much better to do a small test print and use that to tweak your printer, than having to eventually throw away a much larger print because it had a flaw you weren’t anticipating. Kinda puts a perspective on things.Īnd printing a 3DBenchy overall actually saves waste on your printer in the long run. So basically, for every one or two seconds of stepping on the gas, you’re roughly doing the same amount of environmental harm, when it comes to CO2, as printing a single 3DBenchy. For comparison, if you do a single 0 to 60 run in a gas-powered car, this is the amount of gasoline you’re going to burn, about 80ml, from fossil sources, which is going to cause about 250g of CO2 emissions. First of all, we’re talking about really tiny amounts of waste that we’re producing – a Benchy weighs about 13.5g, and, when printed with PLA, which is derived from corn, causes about 60g of CO2 to be released in total, for the production of the PLA, and the electricity used to run the printer. So I want to get one thing out of the way first because it’s a super common complaint when you print a little plastic boat: I don’t think printing these is wasteful, bad for the environment, or anything like that. The Benchy does so much with so little material, and I kind of want to show you how to use them, there are a lot of hidden features and implications on the Benchy that really make it a model that is so far ahead of other single-purpose setup prints. I’ve never printed a calibration cube, well, maybe once, but that was pretty much to show how much of a waste of material that calibration cube was. And I think that’s great! I’m going to argue that this is pretty much the ultimate calibration or benchmark print. I don’t think I need to explain what this is – if you’re watching this video and you’ve got a 3D printer, you will most likely have already printed a 3DBenchy at some point. Hello from the new, old, old, new studio! I’m not quite fully set up in here yet, but it’s usable, and today we’ll be talking about Benchies! The 3DBenchy is an awesome model – but do you know how to use it?
