    Workflow improvement: if you keep the support bases (by adding the raft later) you can ALT-drag the base of a support and immediately attach it to a neighbouring support. That way you don't have to delete every other support and manually re-add it.

    If you select only three supports at a time and hit "parent", Lychee will usually neatly parent the middle support to the other two. You can go along a chain of supports like this, doing three at a time, and it winds up slightly faster than manually placing every middle support with ALT. .

      I also do this it's a very handy trick. Especially if it's supports that are buried. You can move the camera to look at the bottom for easy selection.

    This is the best channel on resin 3d printing properly that I know of, you really helped me out.
    One thing I want help is to understand the best possible ways to print.. hard surface objects that are even.. flat.. or circular. like.. I'm helping a friend and I'll print a vase, a cup.. for clay/ceramic molds.. and I still don't know how I'll orient the objects and avoid suction cups.. I guess I'll simply add holes.. patch up.. and print 90 degrees straight in base without supports.. and pray. but some shapes won't allow that.. (concave lips at the bottom) so I'm at a loss..

    • @J3DTech
      @J3DTech  8 месяцев назад

      These types of shapes are very hard with resin. You do need a hole at the lowest part of the hollowing and it has to be big enough for resin and air to flow in and out during the print to avoid the suction cup.

    what's the reason of not printing flat on the bed besides the elephant foot? artefacts?

    • @J3DTech
      @J3DTech  11 месяцев назад +1

      Quite a few issues, elephants foot is one.
      2. Cant hollow as there is no way to add drain holes.
      3. Z crushing. These printers are not as accurate on the Z as we wish. Prints printed flat on the plate often suffer from being crushed a little.
      4. Stepping, the Z will show more stepping then XY. Items flat on the plate will often have very very bad geoperical patterns on the top and look very ugly.
      5. Can be hard to remove. - I hate mag plates for a host of resin and so won't use them. A large surface like this "can be" a little hard to remove and sometimes damage the corners.

      I sked because I a beginner and I saw your movie just as I was waiting to finish a print I started just last night... a 17cm Liberty Statue that I hollowed after fixing it (it is a free model) in Blender a little over one hour lol and it came out very well on Z no artefacts but the horizontal drain hole I had placed in such way that it will cut all the way through the squared base like a trench didn't worked out as intended. In stead of a trench I got a normal tubular drain hole.. a double as I had a second one a little bit above of the first for same purpose. The trench I was planning to be used to avoid the suction cup created by the base... but the print succeeded. (printer is a Saturn 3 ultra btw).

    In your basic supports video you started with heavy supports on the base for a small object, but in this video for large objects you've used medium supports right from the beginning. Is there a reason for this other than you've just found a better way to support objects compared to when you did the basic video? Thanks. I'm learning more from you than all other RUclips channels and Facebook combined and starting to use Lychee

    • @J3DTech
      @J3DTech  12 дней назад

      @@tonyh3350 For a base with a flat surface all the supports are so close that you don't need to use larger supports.
      And yes I'm always learning, always so newer videos will have more updated processes.
      However on a large organic shape I still might use a heavy support on a large island if I can get away with it.

Up until then nearly all my supported models printed with warped undersides or with right angles printing at less than 90 degrees and I had to print everything on the plate to get the correct geometry. I tried your method in your Supports Basics video, and your advice about anchoring the lowest point with heavy supports is working for me.

    Do you know how to turn off the setting where if you make your support preset either too big or small, it'll automatically switch to either the medium or heavy profile? It's pissing me off, quite frankly.

    • @J3DTech

    I have yet to have this method of support work usably; the flat bottom never remains flat. Every place where a support is touching the surface is a raised area on the surface of the model, so instead of a flat surface I get a field of hills. The model prints successfully, but is unusable.

    • @J3DTech
      @J3DTech  8 месяцев назад

      This has a lot to do with the type of resin you're using. The cause for the bumps is called Z-Blooming. Resins like Conjure Rigid Gray, or Navy Gray have less Z-Blooming then most. I would suggest trying these resins or adding an additional 5-10% tilt to your object to help mitigate this.

    So if the supports have little round bases on each of them, by the time you're done supporting a raft is formed by the supports, so why do you do a full raft also?

    • @J3DTech
      @J3DTech  Год назад +1

      Good question, thanks for asking!
      1.The raft has a lip that makes it easier for the scraper to get under it.
      2. Significantly less complex from a polygon structure than a bunch of feet squished together.
      3. It's easier to adjust the thickness or type or raft then altering the feet of the supports when I do want something different.

    Thanks for your video. I'm trying to do parenting, but I can't get them straight, I mean when I add new support in between two existing with Alt button pressed and connect it to existing - it makes it orthogonal to the base, not like pillar support and for you it seems that your supports are pillars and parenting supports are pillars too in the way they connect to the base (e.g. straight vertical). hopefully I made myself clear.. what is the trick here?

    • @J3DTech
      @J3DTech  Год назад

      Make sure your support tips are about 2.5mm long. And that you have enough space between the two other supports.
      Finally try placing the base of the parenting support lower in the shaft.

      ​@@akarca That depends, if you want to hollow it, it's best to lift it off of the build plate so that you can add holes. This will also lift the model above the burn in layers. Burn in layers can create what we call elephant's foot.
      There are ways to get around the effects of burn in layers, I cover some of them in my guide.

    For Christ sake, just put it directly on the plate! Then, come back and thank me. The way I calibrate my LD-006 is simple: first, I calibrate the level of the plate with VAT ON IT, setting the HOME position. Second, I elevate manually the plate until it is slightly above the film, setting the Z. Now I have a ridiculous micro elephant foot, if any.

    • @J3DTech
      @J3DTech  Год назад +5

      Definitely a great way to do it! There are several successful methods to removing the elephants foot.
      The method you described, burn-in layers compensation, some printers allow for variable layer settings to set a very long rest time on the burn in layers while keeping TSMC enabled.
      However there are many situations where printing on the build plate isn't ideal such as. Hollowing, more complex objects, or larger objects that need to be tilted to fit in the printer's LCD space.
      They are all just tools to be used to fit the job.
