Solidworks - Easy Resin Print Supports

    The biggest issue I have had printing small parts is bed adhesion. LycheeSlicer comes with some powerful automatic tools for building supports, unfortunately they don't know which surfaces are important and they raise the part off the bed surface which ruins one very valuable reference surface.

    My solution has been to painstakingly apply custom supports in Solidworks, by mimicking the automatic tools of LycheeSlicer.  But last night I developed a better method.

1) Create a feature which will easily break from your printed part.

2) In a new sketch plane on the build plate side of your part, offset the profile of the part.  Replace all the sharp edges of the offset with radii.  I find the simplest tool for this job is the sketch fillet.  Exit the sketch.

3) Select your support feature and add a curve driven pattern.  Play around with the settings until it looks right, and you should have something like this:

4) Build a raft around your supports.  Et voila!:

I skipped a few instances of the support pattern.  Your mileage may vary.  My part features were too small for the burn-in layers, but the technique is sound.  If you do a resin print test you will have specific information about the feature size of your prints.  This was my first successful vertical print, and the result was encouraging.  Despite the supports being a single piece they were easy to remove and there was minimal post-processing.

And now for something completely different...

I recently hosted a party and received many gifts. In response I decided to send out thank you cards. Of course, I can't do anything the easy way. So, I took some inspiration from Japanese wood block printing and started working on this. Obviously, I have some work to do, but for a first print in the completed block set, I find it encouraging.  So here's the process: Laser printer transfer - create your design and print it on a laser printer. Use acrylic medium to glue your image face down to your lino block. Let the medium dry overnight. In the morning dampen the paper and rub it off the block with your fingers or a damp cloth. Linoleum carving - using various chisels remove all the areas which are not supposed to hold ink. First key block test - I had to make sure I did it right. From the full set you can see that the pigments are going down in multiple layers. In hindsight I would cut the ocean as one block and use

Pie Cut for Your Thoughts?

Image
       So, the other day,  I'm working on this pie cut problem.  So far, I can print hundreds of these  degreed pie cuts assemble them into a manifold and retrieve the data to create a 3d file which represents the mock up that I have made.  But, what if, I wanted to draw up a 3d file which represented a possible manifold configuration, and then print exactly the number of pie cuts to create that specific item.   Work Flow: Method #1 Print hundreds of various pie cuts --> Build a mockup  -->  Test a mock up -->  Build a new mockup ...  -->  Convert mock up to 3d file  --> ????  --> Profit. OR Method #2 Create a 3d file  -->  Print Exactly the pieces required by mockup  -->  Test mock up  --> Adjust 3d file... --> Print difference of pieces  --> ???? --> Profit.      Both of these workflows are useful.  But from a Solidworks perspective the first method is much easier to accomplish.  And from a time use perspective the second method saves valuable
