The Ultimate Guide to Perfect 3D Prints

[@metalfabman5477]

I'm sitting here at 4 in the morning by our wonderful wood stove with fresh snow on the ground outside watching KZbin on the big screen for 3d printing tutorials, and thought to myself, I need to stop for just a bit, and take the time to let you know just how influential you have been to my journey in 3d printing. I built my anet a8 back in 2017 and I am still using it. Over time I did all the upgrades so it is a pretty respectable printer now for an A8, lol, hopefully some day I'll add a newer more modern printer to the office, but for now it's what I have and still enjoy making things on it. I'm an old guy who's retired after decades under a welding hood and have always been a maker of all kinds of things. I would like you to know that of all the people on KZbin in the 3d printer relm, you are one of only a very very few people that I take the time to actually watch and enjoy your content! Your knowledge base is just amazing and you are very much like me in your willingness to share your knowledge with others. Thanks from the bottom of my heart to you for all you've done to help me along this 3d journey. Wishing you the very best in all your pursuits. You are just a stand out Teacher of all things 3D!! Thank You!😊

Also, check your nozzles people. The brass ones will wear, and the hole will widen over time. A fresh good nozzle also works wonders. Even diff material nozzles such as stainless steel or ruby nozzle.

[@hoffer_moment]

and some of those cheaper nozzles will have QC issues, some rarely even come without a hole. change those nozzles as frequently as you go through 1kg of filament imo. edit: maybe not that frequent unless the nozzle takes a lot of abuse, lol

@@hoffer_moment change nozzle every spool? yeah ok lol

[@hoffer_moment]

@@jimmyc6409 you're right, i tend to need to because i use an untextured glass bed which not only requires a pretty close squash to stick without adhesive but also has had flatness qc issues from the start, so the nozzle routinely hits the bed in certain spots and i just kind of have to deal with it until i manage to win the lottery on these beds

I bought the castle files and dived straight in and printed it first. I forgot about reading the slicer settings. I was stunned at how well the print turned out, especially the bridging. OMG, that turret, getting that draw bridge down and that gate up was difficult but done. Every once and a while I get amazed by what a 3d printer can do and today was one of those. Thank you, Angus.

Great video. I could have used this about two days ago when I started calibrating my first 3D printer. The biggest improvement was fixing the temperature.

Probably the first thing after calibrating E steps and X/Y.

[@AndrewHelgeCox]

With a wide nozzle, like 1mm, you might need an extra high retraction to stop stringing, but then a negative retraction after each move is needed to not have a gap in the perimeter as the filament makes its way back to the tip of the nozzle. This negative retraction is pumping filament out rather than pulling back in. I think that might be called "extra length on restart" in your settings screenshot at 07:40.

[@MakersMuse]

Yep, I find that can help with flexible filaments as well, to help start them flowing a bit better after retraction. It's great to have access to fine controls in the slicer like that!

[@PeterAcrat]

Cheers Andrew. I'll borrow that one. Thanks✌️

[@durbezelo]

In Cura this is called "Retraction Extra Prime Amount". I spent hours trying to figure out why I had underextrusions near z-seam. Unfortunately, in Cura this setting is set once for the whole print, thus does not depend on distance travelled and needs to be adjusted for different prints

[@gadget2622]

Fantastic video. Just want to add regarding the bridging it's kind of a function of tension within the molten filament. Which changes per filament type. But generally going fast and under extruding during the initial bridge moves will help avoid the drooping by pulling the molten filament tight. Too much tension and the filament stream might break, or simply fail to provide a good foundation for the rest of the bridge, so finding the sweet spot for each filament and temperature is key.

[@rpavlik1]

Oh man. What a blast from the past, thanks for reminding me that I wasn't just "rubbish at 3d printing" for the first while owning my hand-me-down Rep2x, there was a bunch of tuning required (much of which was eventually replaced by using/adapting the great FFCP profiles for prusaslicer from DrLex), and that I didn't get to "send job to octoprint, printer turns on, squirts out model, and turns off when cool down complete" level of usability for a long time.

[@86abaile]

Thanks for making this. For whatever reason I have a hard time convincing people what's causing problems in their prints, so this helps. A lot of these I figured out a while ago and I often seem to be ahead of the curve on these tips. So for your consideration, I'm going to suggest that the next wisdom in 3d printing is that we shouldn't bother changing our print speed while trying to improve quality or time. Since print speed only affects the maximum print speed; whether the printer actually gets to that speed is determined by the acceleration setting. Further more, I suspect most of the stresses at the point of deposition are going to caused by speed changes. I posit that best practice should be to determine the max speed at which a given nozzle and hot end can lay down a given filament AND adequately cool it, the printer should then be set to run at that speed (with a conservative margin) and left at that setting for the given profile. From then on for that profile all adjustments for time/quality should then be made to acceleration and jerk, with the speed left alone. As a rule, rather than think about how fast we print, we should instead be thinking about how aggressively we print. I'm currently upgrading my printer though, so I've yet to test this theory.

[@taylormartinez3394]

[@agerlock917]

Great video! You touched on just about everything, but I just wanted to mention that you should check the diameter of your filament with calipers and adjust your slicer settings accordingly. Sometimes failed or ugly prints can be caused by this. For instance, I just checked a cheap roll of 1.75mm PLA+ and it ranged from 1.68-1.70 over the first meter or so. I changed my settings to 1.70mm and I'm printing fine so far. at 1.75mm I would probably be under extruding.

Always good to review and reaffirm what to do when you see a condition. I generally just get by and clean up a part after the fact. But now I am moving from my own R&D to trying to make parts that others want and will pay money for them. I want to make the best parts I can with the machine I have. Review like this helps push me to rethink what I do and how I am doing it. I see more clearly where I have made mistakes in reacting to certain things. Too much retraction, clogs, layer height Variables, Too hot, too cold, not enough cooling fast enough and it goes on. My two main issues are: 1 making round holes really round and 2 sagging bridges. I have put off Direct Drive Extrusion too long, based on input its heavy and the Y Axis will sag??? I think I need to dig deeper, take the time to print test parts and really address all the calibration tools available and finally learn to set feeds in the firmware.

[@printingotb521]

Finally someone doesn't try to fix everything with flow compensations! I'm not alone :D I would also not recommend to calibrate X/Y steps based on a 20mm cube. What I would do is to print something 20mm AND something 200mm long/wide and compare. If the error is the exact same %, the steps likely needs calibrating. If however both are for example exactly 0.05mm off, it's not a step issue but more likely something mechanical like loose belts or even a bad seam or an elephant foot. Imagine calibrating steps based on a 0.05mm measuring inaccuracy over 20mm. If you do and then print something 200mm long, that would produce a much larger 0.5mm deviation. There are a lot of things to consider when measuring accurately (but I know you know this). Caliper accuracy, how you hold it, how hard you press. Ask two people to measure the same part and you rarely get the exact same result. Corner swell, elephants foot, layer seam, how much the pressure lag in the hotend causes differently wide lines depending on how close to a corner you measure. Even how much moisture there is in the filament in some cases.

Great video. One thing you overlooked is the effect of worn nozzles. I hate changing nozzles and recently spent a lot of time trying to dial in some silk filament settings without great results. Eventually I got over my nozzle change phobia and changed them (I have two in my IDEX printer). Both were really badly worn. Now I can get good prints with the silk filament over a range of temperatures. Not only has the print quality improved, but the settings don’t have to be dialed in so precisely.

[@rexxx927]

try taking a "real" hardened one and torch it with a red hot flame and pliers until all is completely burned off brush it up with copper to clean out the ash and polish her back up i usually get 2-5 or more like new uses out of them but it must not have coatings or ones that cant take the heat really none can but Nickle or chrome cr38 all wear eventually smooth in smooth out!!! tip, just hold the nozzle don't crush it the red hot nozzle is soft under this type of heat and is not great for materials and stresses so gentle under extreme heats so heat as evenly as possible so it grows and shrinks together! this is how we clean real industrial extrusion dies barrels and screws that wont clean with cleaning resins or reach i have even resulted to a 600 grit paper to get the grit/carbon off the inside rolled into a cone twisting it with my fingers until its slick avoid the actual tip just the entrance and the tapered area to the final hole but if you hate changing nozzles i may have still wasted my breath but any hooe

[@pauless7]

This tips are pure gold. And here is a fact that shows it: Shipping my printer from Spain to NL, my creality arrived completely messed up. Two supports with the wheels unaligned, one cable of the extruder cutted off, and the elevation screw... Of course... Bent. I fought repairing everything by myself, correcting deviations, welding and bending again... And printed zillion times. Well, guess what? The elevation screw wasn't rectified enough... And now I am ordering a new one cause I cannot print a damn cube smoothly enough...😆

[@kevfquinn]

Worth emphasising what is being talked about here on calibration, for the typical case today buying a well manufactured printer (e.g. Ender 3), is fine tuning - the factory settings will be pretty good, provided other aspects of the printer assembly are ok (e.g. v-slot wheels are correctly tensioned, belts correctly tensioned and not stretched, etc...) so if you have bad prints go through all of that *before* breaking away from factory firmware settings. A corollary of it being fine tuning; any change in steps/mm values should be *small* (1 or 2%) - if you're tempted to make big changes then stop, and find the real problem instead. In particular, I see way too many people thinking that "calibrating e-steps" is solving problems they have - when invariably it's (badly) papering over other real problems. Given the E steps/mm is a function of mechanical physical characteristics of the machine - specifically the stepper motor step size (how much it rotates per step), the micro-step configuration, the effective radius of the hob gear - any change to e-steps done for calibration would be quite small. Fine-tuning e-steps (adjusting the stock 93 to 94 on an Ender 3 for example) means it'll be set well for the particular filament you used to calibrate, but will be out for other filaments. Softer filaments mean the effective hob gear radius is lower for example. If you primarily use PLA then fine, I guess - but to handle different filament types in particular soft TPU it's better to adjust the extrusion factor/flow rate in the slicer to compensate. Changing the flow rate and changing the printer e-steps both have the same effect - just the printer e-steps are best set to a common median (so calibrating for PLA is a good choice because it's relatively hard and therefore consistent), and the flow rate can be used to compensate for different filaments as part of the slicer filament profile. If you're changing e-steps by a significant amount from stock with PLA (say more than 2%) - you're not calibrating the printer, you're compensating for a real problem elsewhere. Examples include clogged hob gear (just clean it with an old toothbrush), partially clogged nozzle, something interfering with the grip of the hob gear onto the filament (e.g. the arm is not properly free to create the right pressure between hob gear and idler wheel, the tension on that is too low/too high or the spring is weak) - or even you're using tight-tolerance (capricorn) bowden tubing with too-tight bends and less "perfect" filament diameter. Even had one where the stepper motor drive current was too far out so the motor was low on torque.
