- Hopefully this video can help you get better in supporting 3d model.
everyone has their own best method, but this is mine.
i learn everything from my 10 years experience dealing with resin printing.

Dennys, please do not stop sharing your superb observations and conclusions. You are the best, and im sure ive seen every 3d print channel on youtube 🙂
Thank you, please help share the words.
Short and on point. Perfect video format.
Honestly
I dont know how to make the video longer.
LOL
@@wangdennys Good! 😀👍
@@retromodernart4426 🤣🤣🤣
@@wangdennys set the recording speed to 0.5 and also talk SUPER slow.
Problem solved!
Did i talk too fast?
I usually do 30degrees in x and 30 degrees in y. This allows the new layers to build without sagging. I auto support with about 10mm distances and then add extras at the start point and the 2 main build edges.
Thank you for sharing.
By going taller, you can also fit more on your build plate.
@@Artmesa yep, agree.
I am learning so much
Thank you for the information Mr. Wang!
this is exactly wut i needed for a few of the models ive been wanting to pring with straight edges! thank you
Welcome
Thank you for the tips !
Yet another great video, thank you!
Thank you
Subbed! Great videos, quick and to the point.
thank you
That's so interesting that the TOP of the model was affected, usually warping and bowing happens on the supported side in my experience, due to undersupperted edges and support density not being high enough. The top edge has never warped in these cases, I assumed due to the bottom layers providing a firm enough base after 10-15 layers after the support transtition. Thanks for amother great video, Dennys!
Actually more like the middle, not just the top.
The middle sunk in because the shrinkage from the support under the middle area.
huh, this seems like a good solution to my problem, thx i will try it out.
This helps greatlt! Thank you.
Thank you
Thank you for this tip!
Great video, get the word out!
Thank you
Good job
wow, very helpful video. thanks for sharing!
Thank you
Thank you for your great Videos
Thank you
I recommend adding a few center supports at least, otherwise you CAN get sag as the resin cures depending on how fast youve got your printer going. I run mine right up against the edge of how fast it hardens, and mostly print abslike unless theres nothing structural about the print. (Art for example). This has the layer drying just as it is pulled off the plate, but makes for very low cycle time and fast as hell prints.
It doesnt happen to the base i print in the video.
Because all of my printer run on moderate speed using tsmc.
But yes on larger object i suggest to put some support on the center to prevent it sunking from shrinkage
Thank you master, saludos
Hi, thx for your suggesion. I have a similar problem about my prints edges and corners. I cant get straith edges and corners. My prints edges and corners are curved, so the parts of the prints which have multiple pieces and sould be assembled, wouldnt fit each other. I will try your this suggession but do you have any other direct one about my issue?
Thanks dude, super good video i will share it well on the forums it's perfect, um, one thing.... Where's (MRP) 2? lol
It is for member and patron only.
But i assure you it wont affect your support result.
Just minor setting for advance support setting for support to be more neat.
I don´t understand why people dont directly print on the buildplate. I usually add a 0.1mm beveled base for easier removal, and then go for it. Yes it can have a slight elephants foot, but it´s not visible because its under the beveled part.
Not all base or flat object can be print directly on plate.
Because there are infinite shape and sizes.
So no harm with having more knowledge right?
There are many cases in functional prints, printed flat on the build plate, where some higher layers of the print need to be supported, the principles Dennys Wang showed here work great for that, too.
Here's an example, consider a 200mm tall part, starting with a circle with a center hole in it, flat on the build plate, then 4 shafts concentric to (attached to the edges of) that circle rise 50mm with another circle with a center hole in it, and so on until the top.
This method Mr. Wang showed is essential and works great for things like that.
Note: The reason one would do a part like this in this way optimally (flat on the build plate) is so that all of the circles and the holes in the center will be perfectly round and of the correct dimensions - when circles or holes are printed at an angle, they can become distorted due to cure-through and/or blooming, and is more complex to correct for.
Does it work on large flat bases? or only small and medium? I have that doubt
Works great on large bases, been doing this for years on large objects.
Yes it works on all bases.
But i will make more video and another video specifically for large base.
I'm new to printing, but after watching this video, it seems to me that if this is the known and correct way to arrange the supports, then why isn't the auto-support function automatically programmed to default to this?
No idea why
how did you decide on the tilt angle?
What about the center ? No deformation at all ? If it is real, it is really a game changer for me 😮😮
What center?
I check with the steel ruler and everything seems straight.
New to resin printing. Why do we angle and support the flat surface, instead of printing flat on the build plate?
To reduce cross section area and reduce peeling force.
@@wangdennys thank you!
Why does the middle not require support?
the edge supports are enough to keep the middle self support
This feels like a trivial problem to solve, yes this will take more resin to create, but I'd much rather have a 99% chance of getting a correctly perfect printed object than printing many suboptimal prints that will end up in the trash anyways. Technically reducing waste by making sure the final product is as requested.
You should receive a salary from the 3D printing community
Why are the ones supported only on the edges not sinking in the middle?
Your question contains the answer 😁
@@wangdennys I guess I'm too dumb to get it
@@jamqdlaty too much supports in the center could cause the middle to sunk because they got pull by the shrinking force of the support around the center.
Hello, i've got 1:64 scale hot wheels rims, should i print it flat or give it 100° rotation like you do on this video? the base models is cylinder. Thanks in advance
Send it to me
I will do live supporting tonight
@@wangdennys I don't think i can give it to you tonight, i'm not home yet. Hope there is similar case like me so i can watch how you put the support on the live
@@1337FLINT. Okay
what the hell?? LOL.. you only suported the edges on the square and the center printer fine? wow.. didnt expected that. interesting.
Yep, it is possible for that small base.
Thank you! What angles do you recommend using?
In the video, the model angle is 10° on x and y axis.
Also, could you please say what printer and what resin you used, those prints look like they have superior surface and detail!
Printer is Mighty 8k
yeah i tried this and it does not work with a model that weighs around 300grams. had a complete failure..
My friend printed tombstone almost full size mega 8k build volume. About 1.5kg materials.
He printed fine.
There are alot of factors as to why a print fail. Print seeting, prientation, support size, also user experience.
@@wangdennys what I had meant was. Printing with that thin line of supports only along the edge with a heavy print wilp never work. I have to fill mine about 75% density to get it 2 work
@@genin69 it works for me when printing big diorama base on mega 8k.
Just need experience.
You could use some 0.6 support tip as anchors.
@@wangdennys i have an object with a flat bottom and some small detail on top for a mold. Its 17cm x 12cm and 2.5cm height. Only way ive had a succesfull print on my mighty 8k is at 35 degree angle with supports on heavy at 75% infill. So ur saying if I have bigger anchors and thicket supports ill be able to print that only lining the edges?
@@genin69 yes
Curious for the the object.
I might be able to do it on next thursday live session
i need supports to my life. bisa om?
Maksudnya om?
