There is a lot of advice out there about how to angle your prints to improve your printing, but honestly most of them are totally wrong. And it really depends on what you are printing. In my case I’m printing tanks with lots of big flat surfaces and I need them to be as smooth as possible. So I discovered how to use trigonometry to calculate the best possible angle to use in order to get the flattest surface on the print.
The tanks mentioned can be found at www.elitegeekminis.com

@forrestegan 4 місяці тому

So, without doing the calculations and based on this comment thread, if my pixel size is .018 (Mars 4 Ultra) then I need to set my layer height to .018? I don’t know if I can even go that thin for layer height, and even if I could wouldn’t that dramatically increase my print time (more layers, longer print time)? Of course, if you’re going for the highest level of detail, time to print needs to be ignored. I started out using .05 layer thickness but already considered going down to .03 for my prints. I think these layer heights are getting so thin that we’re reaching a point where you need a magnify glass or microscope to see the layer lines, even if we don’t optimize the angle. Not trying to be lazy choosing my angles; however, I may try some experimentation with some test prints to see if it really matters with my tiny .018 pixels.

For me what worked the best for the past years from working with DLP printers is it depends a lot on the model.

Great video. I 'm impressed how clear the explanation was. I did some more research on physical dimensions of my printer. I found that single step of Z axis motor moves by 0.000625 mm. So, setting layer to 0.051 mm would require 81.6 steps. Printer would round it and proportions in Z axis would be wrong. So it's better to calculate angle correctly rather than change layer height to mach pixel size.

SUPERBB. Thank you so muchh. I own photon mono. I know about 44.43 degree thing. I always did that. What I DIDN'T know is that you can change the layer height to 51 microns! I always thought that the printer can't do that (0.001 mm Z axis step). This is mind blowing. The option is always there but I didn't realise that until I saw this video. Now I can make the perfect cube like you did! thank youu

I tried this today with my SM4K : IT WORKS !!! Thanks for the explanations. The formula can even be improved for a smoother finish. After watching this very instructive video about the printing angles on 3D printers, I noticed that these parameters are all calculated for prints parallel to the pixel rows. many of my friends and I noticed that rotating the parts on the build plate gives smoother results. I took my old calculator (Yes... the 35 years old one I had at school) and after rotating the part by 45° on Z axis, the new formula is : H = layer height W= pixel width A= Angle A= Arctan (H/Sqr(2W²))

Really nice video, thanks for making it. I have a question though. Just got a resin printer (have multiple FDM printers) and haven't printed anything as I wait for the wash station to come in. I was wanting to try to print a cartridge shell I designed for a retro computer. It is a two piece shell that snaps/screws together. One side of each shell is completely flat. No crazy internal angles or anything. Should I still print it at an angle or can I print it flat on the bed? Someone told me that getting a large flat surface off the bed would be hard to do and dangerous for the bed of the reservoir. I look at it from a FDM point of view and I see a 45 minute resin print if I lay it flat, and a 5 hour print if I turn it at an angle. I was worried also that all those supports underneath it touching the flat cartridge surface would really make that smooth surface bumpy too, besides the long print time. Just wondering if this is something I shouldn't tackle with resin and stick to FDM. Any advice?

@kenengel620 6 місяців тому

Why did you use supports on the flat cube? I print a lot of enclosures for electronics projects and I print right off the build plate. The biggest issue I have had with it is one you glossed right over. If you look at the bottom side of your flat cube in your video, you can see a big difference between the layers making up the bottom side and where it transitions to the vertical sides. I even sometimes get gaps and hole at the transition line. To help with this I started to make the higher exposed bottom layers include the entire bottom side of the model. That way there's better adhesion at the transfer line. As long as the side facing the build plate is flat it works great. I even have good results printing text and images into that side.

It can be, but you are going to have to adjust the file because the bottom layer will expand when printing flat on the plate. It is called elephant foot and you have to narrow the file where it touches the plate to compensate.

Great video. Couple of questions: 1. When you demonstrate optimizing orthogonal flat surfaces, you only optimize the angle in the Y dimension. Why not also X and (if relevant) Z? 2. In some examples you nudge the layer thickness to achieve a 45 degree angle. In others, you nudge it to achieve a seemingly random angle < 45. Why not always shoot for 45?

@TrueEliteGeek 2 роки тому

Some printers don’t do as well as others at supporting a 45° angle. The mini 4k for example seems to have a hard time with a 35 layer height. And sometimes you need smaller or bigger layers for other reasons. But at 45° you are locked into a single layer height.

@ddtalks2821 2 роки тому

(9:40) - Because you are printing a Cube (or an object that has two flat surfaces at right angles to each other) and using ArcTan to get the 'perfect' angle, the other side (perpendicular) will always be off, UNLESS you set your Layer Height and Pixel Width Identical so you get a 45 deg angle. What if your two flat surfaces that connect along one edge are not perpendicular? You are going to get 2 different angles, only ONE of which is the perfect angle... Also, you have printed your cube along one edge of the cube. Does this also apply if you printed off of one of the corners? How does that effect the 3 sides that are now printing in a non-flat/perpendicular orientation to the base plate/vat?
