Learning about 3D Printing * 6 Things You Need to Know



I deserve SPRO the doctor backs Channel and today I'm going to help you become a successful 3d printer by providing you with six special hints things that I ran into when I started 3d printing that will help you be more successful and the reason this is important is because 3d printing is not science it's not engineering yes there's science and engineering valve but no one can give you a precise formula that will work with your printer every time and the reason is it's a bit like baking every oven the temperature is a little different every batch of flour is a little different if you're at a higher altitude you need to bake things a longer period of time if the water is different baking is different well 3d printing the temperature of every hot end every nozzle is a little different the calibration every printer is a little different every brand of filament is different there are all these variables and it's a bit of an art in fact because it's a bit of an art that's why I find it so exciting you get to build this skill as an artist a 3d printing artist so stay tuned and let's learn some things together okay you have that box that just arrived at your doorstep with your new 3d printer maybe it's a kid maybe it's fully assembled you're ready to open it up stop you need to do a couple things first the first thing you need to do and this is hint number one learn about all of the parts of a 3d printer before you even open up the box sure there's an instruction manual it will tell you how to assemble it but if you have a basic understanding of the components of your 3d printer before you get started your life will be much easier you need to understand how the filament is pulled in by the extruder it's fed either directly to the hot end or through a Bowden tube to the hot end at the hot end you have a cooling fan you have a nozzle it lays print filament down onto a print bed that is probably today heated your system has a power supply it is firmware you need to know what these things are before you get started so how do you learn there you're in the right place watch a video so up in the corner give you a link to the 3d printing demystified series you can watch that but there are hundreds of excellent videos on YouTube about 3d printers spend some time learning the components before you open the box oK you've successfully assembled your printer or at least taken it out of the box and you think you're ready for your first print stop again because even if your printer says it has Auto bed leveling you need to check the bed leveling before you begin because if it's off if it's too far off and the auto bed leveling can't adjust or let's say you're using a Cree ality under three there is no auto bed leveling if that that isn't right your first print will not adhere to the bed it will come off it won't stick properly maybe immediately maybe an hour into your print there is nothing more frustrating than a print that tips over 25 percent of the way done so learn how to level your print how watch a video once again there are a series of videos I have a video on auto bed leveling an under-five that really applies to many of the Cree allottee and the standard Cartesian printers that might be a good starting point so that's hint number two level your print bed even if you think you're ready to print because it has auto bed leveling now hit number three is going to be controversial because I'm going to recommend you spend some extra money precisely about 20 bucks and you don't absolutely need to spend this $20 it's for peace of mind it's so that your first experience is pleasant and the 20 bucks is for a two of magic ooh magic goo is a special formulation of a material that you apply to your print bed before your prints you can use one application of magic goo for many prints in fact I'll just a damp cloth can be used to refresh an application of magic goo and I have found it significantly reduces the likelihood that my print will come loose from the print bed now magic cool looks like a regular child's glue stick but it's not it's a little different and yes you could use a little glue stick yes you could use Windex yes you could use hairspray yes you could use a variety of things I think it's worth the extra ten twelve fifteen cents maybe less maybe a little more to use magic goop so hint number three use magic oh so you've printed the print the model that was on your SD card it came out really well you're ready to run over to Thingiverse to find another model to print but wait you need to do something else you need to learn about slicers what is a slicer well basically a slicer takes a three-dimensional model and converts it into individual layers that can be printed on your printer a 3d printer is like laying bricks a layer at a time then you move up and another layer so you need to learn about slicers well which slicer should you learn about if you're using a proofs of printer use of proofs of slicer it used to be called slic3r Prusa addition it's now called the Prusa slicer it's a finely tuned ecosystem it's much like the Apple ecosystem you buy an expensive iPhone the software comes from Apple the hardware comes from Apple yes the proofs of printers are a bit more expensive but you get an integrated ecosystem the hardware comes from Prusa maybe as a kit may be assembled and the slicer comes from process so if you're using a Prusa printer use the perusal slicer for everyone else I think there are two good choices to get started there are many more opportunities to select and play with an experiment with slicers I think there are two choices you should try most low-cost hobbyist grade printers recommend you use Kira I liked Jarrah I find it relatively easy to use in the basic mode many printers come with a profile setup for Kira on SD card unfortunately it's offering only for a Windows machine I'm on a Mac so I have to more or less find a profile we'll talk about that in a minute but there's another opportunity there's another choice and that's matter control by matter ackers it's a very easy to use system and the advantage is that you can plug your printer directly into your computer with a USB cable well you've been told you can do that with Kira sure I guess you can I've never gotten it to work and many people have trouble using Kira over a USB cable so if you prefer using your printer or you think it'll be easier for you to get started with your printer directly connected to your computer I recommend you to try matter control by matter hacker now the slicers not as good as Kira and your prints might not come out as perfect but it's a great place to get started in fact once you become more advanced if you're using matter control connected to your printer you can slice your model convert it to the right format for your printer and Kira and then load that file into matter control and print format or control so the summarized hint number 4 if you're using a Prusa printer use the Prusa slicer otherwise cura is a fantastic printer but if you want to directly connect your printer to your slicer so you don't have that step of loading to an SD card and finding out how to put it into your printer use matter control hint number 5 you go to use a slicer and your printers not listed what should you do well it's really not very complicated there really a limited number of styles of printers in particular in the home marketplace most of them are cartesian style printers let's say you're using AK reality printer maybe you have a Cree LD ender 5 and the Ender 3 is only listed in your slicer or maybe you have a printer from monoprice it's not listed in your slicer we'll find a printer that is similar to yours select that and all you need to change are the dimensions of the printer the X the Y and the z-axis and then give it a try in all likelihood it's going to work fine now there's one caveat if your printer has auto bed leveling then you'll need to have a special G code a special code that sent out at the beginning of a print to auto level the bed that should be listed in your printer manual it's generally the same code so once again select a printer that has auto bed leveling and you're probably going to be ok however if you don't have auto bed leveling do not select a printer photo bed leveling because your printer may not understand that particular G code so hints number 5 was you can use any slicer with any printer just select a printer that's close and change the dimensions now as you become a 3d printing artist you'll want to fine-tune your slicer profile but that can wait for another day it's number 6 it's not you it may be the filament very often the filament the chips with a number of low-cost printers stinks it's terrible and you go to do your first prints it comes off the print bed it strings alive it doesn't look very good just try a known consistent filament I recommend two that are easy to get anywhere in the world one is hatch box PLA it's carried by Amazon it's very inexpensive and I find it very reliable maybe it is not the absolute best filament but I think it's the best filament for the cost another filament which is slightly better you'll see the layer lines a bit less is matter hackers build series PLA that can be ordered directly from the matter hacker website in both these cases I like to print a little hotter than is recommended on the label so I print them at about 206 degrees Celsius with a 60 degree heated print bed that's been treated with yes magic dough now I have a bonus in for you watch all my videos just kidding no in fact the more time you spend watching videos about 3d printing I'd recommend you start with the 3d printing demystified videos on my channel but there are a lot of excellent videos out there and you'll need to watch a video more than once it'll just sort of soak in and after time you just get it I guarantee it anyone can learn to master 3d printing you just need a bit of time and patience so I hope this was helpful I hope this will help you get started with 3d printing if you're already 3d printing I helped maybe there's something you learned here if you did give me a thumbs up subscribe to the channel click on the bell so you're notified when I have new videos thanks have a great day and let's continue to learn things together

  1. Good tips for beginners. Cuts through some of the hype and spells out what beginners need to do to get started.

  2. Very good video. Much. All of what you said, is really common sense. Albeit a delayed grasp of it's identification, it's still available for eventual recall. It does get easier with time, but it helps immensely to watch tutorials such as yours. Thanks for the video.
    What slicer would you recommend for a Creality printer.

  3. Hi, thanks for the excellent tips. The PLA residue left on my buildtek print bed after a print is very difficult to scrape off. Will Magigoo make PLA release easier from the print bed?

  4. Another great video, I really appreciate the fact that you don't limit people to just watch your videos. I think you are one of the best you-tube channels for 3d printing, but others have good information also.

  5. Your videos have been very helpful as I learn about printing ahead of getting my first printer. I'm looking at either the Ender 3 or 5.

    Do you think that the increased stability from the external frame and the fact that the print bed does not move x and y justify the increased cost from the 3 to the 5?
