Re: OpenSCAD clone for Android (ScorchCAD) - 9 years ago

ScorchCAD does have the ability to export STL files (under the main menu "Export STL File") . For now ScorchCAD is not open source, I don't see that changing any time soon. Scorch

Re: OpenSCAD clone for Android (ScorchCAD) - 9 years ago

@maso, you are right "hull" is not supported. It is one that will require a lot of work so it probably will not be next to be included. However it is probably one of the more interesting problems I need to solve so I will probably at least be thinking about it. Scorch

Re: OpenSCAD clone for Android (ScorchCAD) - 9 years ago

QuoteQuackingPlums Why does it only support a subset of the OpenSCAD functions? Does it use the actual OpenSCAD codebase or are you having to implement each feature independently? ScorchCAD does not use any source code from OpenSCAD. The user interface and SCAD interpreter were written from scratch. The Constructive Solid Geometry (CSG) code was derived from the javascript program OpenJSCAD. I

OpenSCAD clone for Android (ScorchCAD) - 9 years ago

For anyone interested there is a free clone of OpenSCAD for android devices that was recently released on the Google play store. The app is called ScorchCAD. The initial release of ScorchCAD does not have a complete set of OpenSCAD functions but I think there are enough functions to get a start on an OpenSCAD project while away from home. I am the author of ScorchCAD and I plan to keep adding

Re: What Z-corp ink is made of - 15 years ago

I have gone down this Epson print head path because I thought the piezo head would be able to print a variety of liquids. My personal experience has been that it is difficult to get the Epson print head to print anything other than ink that comes in an Epson compatible cartridge. I tried matching viscosity and surface tension by mixing water, glycerin and liquid soap. Water: base material G

Re: What Z-corp ink is made of - 15 years ago

The different colors on the Epson printers are all integrated into one assembly. In the single assembly each color has unique printing ports. Since each color has its own set of print ports Keeping the catalyzer and accelerator separated until they are printed would not be a problem. One problem, I have not been able to get anything other than Epson ink to print from an Epson printhead. I am

Re: STL to 3d array - 15 years ago

Any thoughts about using multi-page tiff (or other image file type) to store 3D model data. Using an existing image format to store the 3D data would: 1. Enable using an existing image viewer to look at the individual layers. 2. Leverage the compression algorithms already developed for 2D images 3. Allow the use of different colors to represent different materials (main material, support materia

Re: What Z-corp ink is made of - 15 years ago

The Soligen process looks great. I know that a few of people that roam these forums, including myself, do some aluminum casting. Printing molds would be very useful. I wonder if they use straight colloidal silica or if they have other additives in the binder. It looks like they also fire the printed object in the alumina powder before it is removed.

MSDS for Epson ink: Viscosity < 5 mPa-s MSDS for HP ink: Viscocity > 2 mPa-s Water is about .7-.9 mPa-s (The HP print head prints water without any problem.) I have not been able to get the Epson to print anything other than Epson ink consistently. (I plan to try matching viscosity) Fernando, Do any of the UV resins have a viscosity this low?

Re: What Z-corp ink is made of - 15 years ago

I am not finished exploring different materials yet. I put the video together with the best material combination that I have found so far so Gene, et al, could see what I was up to. I am holding off on automating until I know what materials I want to use. I might switch to an Epson printer to take advantage of the piezo print head. I don't want to spend a few months getting an HP to work then

Re: What Z-corp ink is made of - 15 years ago

This video should help answer some of the questions you have about my setup. I just switched ink cartridges so I left the black ink in for the video. Usually I run it with water. (I have switched to distilled water with the new cartridge). At the end of the video one of the rectangular tubes is a little deformed. When I picked it up for the video I crushed it a bit.

Re: Twin Cities, Minnesota (burrr) - 15 years ago

Rick, You can buy steppers straight from Keling. Their is a link from the reprap.org page on steppers. They always seem to be in stock but they are $29.95 VS. $25 from RRRF. I am a little confused by this since the RepRap page references the Keling_KL23H51_24_08B but links the page for the Keling_KL23H251_24_08B (Note th 251 vs 51) probably worth asking about his in the electronics section o

Gene, I will put something together for you in the next few days... What I have is very limited and requires manual addition of powder to the build. You should be able to recreate what I have in one or two days. I will be interested in how the Epson works for you. Which Epson model do you have? Scorch

This is great stuff guys, keep it coming...

Re: Extruding in a liquid - 15 years ago

My vague plan was to print on a pre-frozen plate of steel. I would bring the printer into the cold environment only when I want to try printing. The printer and water temperature would slowly decrease in the cold environment. If printing continued for a long time a small heating element (or heated isolated bag) might be needed to keep the water at temp. My guess is that -10

Inkjet printing in the cold. I will add that to my January to do list. Sounds potentially more useful than blowing bubbles. (Frozen soap bubble drifting by) Small quantities of water freeze quickly when it is cold. I think it was between -5 and -10 deg F when I took this picture. Scorch

Re: What Z-corp ink is made of - 15 years ago

Here is my data dump of the main combinations I have tried. Below is a picture of a bad case of "curl" so you have an idea what I am referring to when I note curl below. (Curling is really just shrinking. More shrinking on the side the liquid was sprayed results in a curling effect.) Here are the powders I have tried. If I list two components they are 50/50. -Portland Cement (Curled) -Portla

Re: What Z-corp ink is made of - 15 years ago

Here is a pic of some small pieces I made using 50-50 mix of water putty and weldwood. These are pics of pieces that started out twice as long as they are. I broke them in half testing the strength. I did not optimize the mix ratio, 1:1 is the first ratio I tried. I think less weldwood might be better. (The ruler in the pic is has inch increments) Here is a pic of me squeezing one of the

Re: What Z-corp ink is made of - 15 years ago

My setup is pretty rudimentary. It is an old HP printer with the paper feeding mechanism ripped out. I made a small (flat) platform to place the powder on when I am printing. The print head is ~1/8 inch wide so that is as wide as I can print without moving the powder. I am holding off on doing anything elaborate to get bigger print area until I am confident I can get the powder to hold togeth

Re: What Z-corp ink is made of - 15 years ago

Thank Gene, the information you linked is very interesting. Recently I have been experimenting along these lines. I have an old inkjet setup to print on layers of powder. Adding layers of powder is a manual process and I can only print 1/8 inch x 1/8 inch x 3 inches for now. My setup in pretty limited but I have been able to test quite a few powder configurations.
