3d Tutorial: Model A Sacred Merkaba For 3D Printing

In this quick tutorial, we model what is known as a Sacred Merkaba for 3d printing or digital asset design.  Symbolic of ancient spirituality and mysticism, this shape has been part of religious iconography for thousands of years.  Geometers and mathematicians recognize it as a Stellated Octahedron, or Star Tetrahedron.  I'm using 3dsmax 2012 for this example, but the techniques can be translated to any capable polygonal modeling package. 3dsmax: Blender 3D:

realistic model water?

I have a model PT boat 109 ( in 1/72 scale) and the propellers are broken. I figure the best way to do this is to just throw the boat in a diorama scene, so it is at the waterline. Can anyone help, because I have no idea how to do the water, and i was wondering if there was any realistic water things that I can make at home, or buy for pretty cheap.

cardboard 3d models

First, you'd have to be very careful not to cut yourself (a leather glove to hold the piece helps). If you print the pieces for a cardboard model, instead of cutting, it'll look better if the pieces are sliced. These are the steps that I take: 1. After printing the models, I cut the pieces leaving 1/8 to 1/4 white space along the edges. 2 I use 12/24 pack cardboard from soft drinks (the cardboard from hot pockets works also, but its harder to cut) 3. use a glue stick to transfer the pieces to your cardboard and roll any round object to remove any bubbles. 4. when dry use a pair of scissors to cut the pieces. 5. lay the template face down on your material and use a pen to trace the outline. if using cardboard, use a box cutter blade and slice the parts out, slicing to the line of adjacent pieces. For slots, cut the width thru the cardboard, and slice the required length. Use an exact-o knife to cut the ends, flip over and trim. I've built over a dozen models and my three grandchildren love them.

Modeling Mathematical Objects for 3D Print in 3dsmax or Blender3d

Hello, everyone.  I'm making my first post here to share some techniques and tips for getting started with polygonal modeling of interesting mathematical shapes, which could be used in 3d printing.  Math objects are quite popular in the 3d printing community due to their seemingly complex visual appearance, and overall unique aesthetic for creation of jewelry and other useful printed objects.  These tutorials are for use primarily with the modeling and animation software, Autodesk 3dsmax, or the free open-sourse Blender 3d.  However, the basic principals of these techniques can be translated to almost any capable polygonal modeling software. 3D Tutorial | Modeling Triply Twisted Torus With Holes | 3dsmax 3D Tutorial | Model A Mobius Strip Pendant | 3dsmax Modeling a Mobius Strip Pendant In Blender 2.73 3D Tutorial | Model a Scherk-Collins Saddle Surface Ring | 3dsmax 3d Tutorial | Voronoi Style Bracelet | 3dsmax Model A Voronoi Style Bracelet In Blender 2.74 These are but an example of nearly a dozen different mathematical and abstract models at my channel.  All tutorials are 100% free, of course, and I'd be happy to help you with any issues you may face along the way.  Keep in mind, in order to follow along with these videos, you will need to use the Autodesk 3dsmax software, or the free Blender 3d software, and have at least some intermediate  experience in polygonal modeling in general. These tutorials are not intended for total beginners to 3d modeling, unfortunately. Enjoy, and I hope you find something useful.

Anybody want to model "reflux" in the circulatory system? Physical model or computer pipe model!

My wife just had an amazing success when we went down to Newport Beach, California to get venoplasty to relieve many of  her symptoms following a stroke.  We pay for national medical insurance in Canada and this treatment is not covered.  (Even though it clearly works, )   One road block is that an expert doctor here could not find any evidence of reflux in blood flow to or from the brain.  (Some MS patients have damaged valves in their neck veins).  Now, given that each heart beat raises blood pressure from 1.5 psi to 2.3  psi about once every second and that valves are actuated by the blood flowing backwards, I find the "expert doctor's" results impossible to believe.  I am not totally without knowlege in that area either because I made a low pressure airlift pump this year  that has a much higher lift submergence ratio than the normal ones.  (The airlift in a bucket one). I was told that the maximum  lift to submergence in these things was probably not much more that 10 to 1 but I managed to get over 20 to 1 lift to submergence primarly by reducing reflux.    Also, I observed that the effects of this reflux can extend conciderable distances from the "valve" itself and are different in small tubes than in big tubes.  Therefore it is possible (Likely even) that a damaged valve in a persons jugular will have its primary effect in a capallery somewhere in the brain up to a foot away from the damaged valve.  So if someone made this model, I think it is likely that they can contribute to the rapid advancement of medical science!   Brian White

Advice on how to go from 3D model to laser cutting vector file?

Hello,   I've been getting my feet wet in 3D modeling to try to build board game inserts. These are generally a series of boxes and trays that fit together to hold components and fill the space of the box properly. I have access to a 3D printer, but I can't figure out how to go from my model (in tinkercad or sketchup, generally) to the 2D vector files of the components I need for Corel to print them on the laser cutter. I suspect the process is more than someone could explain to me in the confines of this forum, but if someone in the know could give me a push in the right direction to find the resources I need, even that would be great! I've done a lot of research trying to figure this out, and all I have come up with are some Sketchup plugins that no longer seem to work, or websites that will lonely let me build one box at a time with no extra features (like scallops for card draws). Thanks in advance for any help anyone can offer. Todd

Obtaining helical slices from a 3D model

Hey guys, I've begun to work on a volumetric display for a school project like the one in the link at the bottom of this post but I can't figure out a good way to obtain helical slices of the 3D model which I intend to project. I could do it manually by subtracting the "negative" of the helical screen from my model in Solidworks and then take a screen shot, but this would be pretty time intensive since I would need 360 shots(360 2D images from below the model with the screen negative rotated one degree each time). Is there any program out there or add-on for solidworks which could automate this process? Or even a functionality in solidworks that I haven't thought of? Would appreciate any advice you have on this subject. Link To Helical Volumetric Display Video:

Does anyone have ideas about how to make the sphere part easily? The criteria for my model sphere is that it needs to be:     Roughly 60cm in diameter (I believe the original was ~58cm)     Strong and rigid enough that I can attach the four antennas     Light enough that I can hang it from my ceiling     It is okay to be a little rough (i.e. it doesn't need to be polished steel or whatever) Right now I'm thinking I should get a bunch of pieces of hard-cell foam, stack and glue them, and carve a sphere. Then I'll sand it smooth and spray paint it silver. Is this a good approach? Any other ideas for the project?

Model a heliostat with a drill press, laser pointer and mirrors?

Mechanical Heliostats were important scientific instruments over a hundred years ago and one mirror heliostats were often used to focus sunlight on an experiment. Better mirrors became cheap and 2 mirror heliostats replaced them. Then electric light killed off both types.But now, solar energy is becoming important again. Big fairly low efficiency mirrors can be made with mylar stretched across a frame. Perhaps now is the time to get 1 mirror heliostat research going again! (With low efficiency mirrors, 70% efficiency becomes 49% if you use 2 mirrors to reflect the light) So you get less efficiency for twice the expense if you use 2 mirror heliostats!But first we need to model the process. It just takes too long to test your ideas outside! Here is the start of my model of mirrors on an equatorial mount (also called a polar mount) and the sun moving on the celestial sphere. I think that it will end up being very useful. I just gotta find the right mirrors and the right laser pointer. A heliostat with the mirrors moving at one rotation every 2 days, can do this perfect reflection but it is limited to certain angles because the mirror must be upright on the mount.In my model, I have left out the earth's surface for them moment. So we will just model the suns movement, the heliostat mirror movement and have a target to see how much the reflection moves too.Brian

Building a convection model for plate tectonics and ocean currents

I'm building a model to show our museum visitors how convection works related to plate tectonics.  (It can also be used for ocean currents.)  I'm stuck on the heating source, though, because we cannot have open flames. The model is a cell of water, about 0.5" wide X 10" long X up to 8" high (depending on water depth). I would to implement some type of circuit with a resistor that produces heat at the bottom, and inside the cell, and battery powered.  At the top at either end would be ice cubes, to cool the water so it falls back down and recirculates.  To see the currents, the ice cubes have blue food coloring, and I use a long pipette to inject coloring at the bottom near our current heat source, and mug of hot water. I'm having trouble finding information on: - what type of resistor (how many ohms?, anything specialized for being submerged?) - how large a battery/ies for a 4-hour day on the floor (rechargeable, of course) - other steps to prevent corrosion It will need an on/off switch and a battery connector, too, of course... I'm sure I may be missing some other important things to consider, too. Any feedback would be great. Thanks~ -Adam-
