every printer can be capable of batch printing with some careful tuning and considerations so you too can be able to create the same part over and over with consistent results let's get started [Music] 3d printers have widened the scope of what is able to be manufactured from high detail one-off 3d designs to small production products it is made as significantly easier to streamline the prototyping and manufacturing process for hobbyists and industrial designers alike while 3d printers excel at the highly customized 3d models they also fill the ever-present niche of a small scale manufacturing device that can produce the same part with consistent results all well being able to iterate it on the production line and still being cheaper than going with injection molding this is called batch printing before you even get started it's important to consider whether or not batch printing is even the right choice for you and your specific 3d models by batch printing you minimize downtime for your 3d printers because if you start a print at four-thirty that's only gonna be an hour then you're gonna spend all that time when you're gone away from your printer or it's just sitting idle if you do a batch print you can have a 16-hour print start at 4:30 it's printing out 12 parts and when you get to the office the following morning it'll be just finishing up that print so you can pop them off and start up a seven-hour print so that before you leave the office again you can start up another 16 hour prints and just keep the printer constantly moving instead of having any downtime where it's just sitting there waiting for you to do something with it most 3d printing slices of settings for minimum layer time or minimum print speed and this is done to make sure that every layer at least takes a certain amount of time to give the plastic enough time to actually cool before it moves on to the next one if you have a really small part it's likely to activate some of these settings to make sure that it has time to cool down so if you have a really small part and you're trying to print one it will slow it down but if you print three of those same parts there may be enough time where it doesn't need to activate those settings so it's potentially possible that you can print three part or one part in the same amount of time if your printer features some way to use an SD card or USB Drive to store all of your cheat code you can use that device to organize all of your g-code based on the print time and also if you're using G code just saved to an see card and you have all the same machine you can just copy and paste that G code to all of your machines so that they all have the same plating and you don't need to resize every single time for every different printer by minimizing downtime by batch printing you're also minimizing your pre and post processing that's needed to be done like applying bet adhesive or waiting for its heat up or taking off your build plate flexing it scraping off your parts you're only doing that a couple times per day instead of every couple of hours and by batch printing you can just set a timer to come look at this every so often instead of having to get up from your desk come over do all your adjustments start the next print and go again it gives you a lot more time to focus on other work instead of having to monitor your printers all the time [Music] before you start batch printing here's some key points you can have on a checklist to make sure that you hit all the marks to be able to start batch printing on your own make sure that your 3d printer is well tuned because any sort of retractions it blobs stringing under extrusion tissue that you have is just going to compounds by having multiple parts on the build plate effectively making one build plate of wasted time be sure to check out our top ten calibration prints video to see what we do when we want to do any sort of batch printing or to just give any printer a good tune-up over time the adhesive properties of your build surface while we're down so whether you're using an adhesive that you applied to it or it's some sort of adhesive sheet you want to make sure that both are nice and refreshed before you start a big batch print if you're using an actual adhesive that you apply make sure to wipe off everything you can whether it's water soluble or you need some sort of chemical like isopropyl alcohol clean it all off and then reapply it you don't need to go overboard just enough and a good crosshatch pattern across your bed surface if you have some sort of adhesive sheet we knit off with the little isopropyl alcohol so you can get rid of any fingerprints or oils from your fingers or any sort of debris from the filament dust or just dust in general so make sure that your 3d printer has the most of the heats of qualities that it can like I mentioned previously bed leveling is very important so make sure you run through any calibration wizard or auto bed leveling sensor to make sure your bed is level then you can start with some calibration prints you can either find a specific bed level calibration print or just do a rectangle or just start your batch print and see how the first layer go start with the skirt then look at the parts see if I have things running smoothly and if it is let it ride if it's not you can start over instead of committing to an entire wasted batch print another thing you can do to minimize the problem of running out of filament is just having some sort of film and sensor and these come in different forms and not all are created equal because the some just check to make sure that there's filament in the sensor and others actually check if the filament is moving this one will see if there's a jam and will usually pause the print so that you don't have a failure whereas the other one if you get a jam it's just gonna keep moving because there's still filament in the switch and some filament spools actually have the end of the filament taped to the spool so if it runs out it's gonna stay taped to it it's gonna get jammed in either your Bowden tube or your filament sensor or even sometimes get all the way to your drive gear so you want to make sure that you know that your filament manufacturer doesn't tape it before that you actually use it on a badge print in case it runs out it doesn't cause any problems take a look at the slice cheat code for your batch print and look for any thin parts anywhere where it might tip over because it doesn't have enough surface area to actually keep it attached to the bed whether it's support or just a weird spot in the model that starts out really thin and grows bigger you basically want to minimize in any way parts that can fall over still here has a very broad flat base which makes it easy to stick to the bed but for something that's a bit more narrow you may want to add a brim to really attach it if it's even smaller you can consider adding a raft but a brim is usually enough to get the job done yes it will add more time to your post processing to remove the brim but to me that's preferable to just running the risk of one of my parts falling over and ruining the entire batch again [Music] now if your printer and you just don't feel like it's capable of batch printing you don't trust it enough it's got some weird issue that you don't think makes it good for batch printing make sure to keep an eye out for any 3d printers that have really large beds because those tend to be pretty good at batch printing the craft bought excel has a really large bed which makes it perfect for batch printing and because it's tall it doesn't limit you for future use so you're not just limited to doing very short batch prints you can do tall batch prints or just one really big and tall model and then of course there's dual extrusion 3d printers that have the nozzles mounted to the same head something like the old say maker s3 the s5 the lulzbot Tad's pro or the Rays pro 2 since both nozzles are mounted to the same head they're effectively single extrusion for any sort of batch printing but they all feature a really large bed so you can do a lot of printing all at once there's another side of for dual extrusion that sure works really well for batch printing and that's idec's does the crop up flow idec's the krappa flow I'd XXL there's the raizy to be an 3d Sigma Sigma X and epsilon and then the maker gear m3 ID and ultra one they all feature two separate tool heads with two separate nozzles so each of them can print independently of the other now they are all locked on the x-axis crossbar which means they have to make these same Y movements and the same Z movements as they all rely on the same bed but they aren't tied on the x axis so you can print with both nozzles on the build plate at the same time effectively giving you two printers in the space of one now with these two you can either do duplication mode where they were following each other on the build plate mimicking the same moves or there's mirror mode so if you have your parts like maybe exhaust manifolds you're printing two of you can have the moving opposite of each other instead of having to print the exact same one twice whether you're an engineer in the industry looking to maximize the efficiency of your production line or your hobby is just looking to get the most printed parts done for all of your projects at once batch printing is a versatile technique to keep in your back pocket is there any tip here that I didn't mention that you find useful for batch printing or maybe you just have a question about batch printing in general because you haven't tried it yet I'd love to hear both in the comments down below for those of you about to embark on your first batch prints of luck to you i'm alec from matter hackers thanks for watching hey there thanks for watching that video on edge printing I know that it's super satisfying when I'm batch printing to be able to just pull off a build plate and it's covered in perfectly printed parts so I hope that you try batch printing as well you want to read some
