I will tell my research that i have done earlier here.
CMYK is used for print pieces like brochurers and business cards.
For RGB we need to start on black paper but we can't add light until we reach white because light can't be painted on surface, what does this bold content means to say?

Hi All,
I am looking to determine how these Vases where modeled using maths on this webpage https://www.3dforprint.com/3dmodel/sine-wave-vase-generator/2116. It looks like the surface is parametrically defined and wrapped around a cylinder.
Interestingly he mentions

int bd= 15;
int ad= 5;
while(ad!=9){
System.out.println(bd);
ad++;
bd++;
}//output 15,16,17,18
do {
System.out.println(ad);
ad++;
}while(ad<=9);//output 5,6,7,8
thanks for the help
A 3d printer that could print metal and other materials would revolutionize everything. The only problem is that metals have a really high melting point, so if you try to get a metal hot enough to bind to the other metals in its vicinity it would probably destroy the bonds of the neighboring...

This is not the first study I've seen discussing potential risks of FDM airborne byproducts. It's the reason I bought a fully enclosed unit. However, it's in my home which at the moment is extremely small. It's less than a meter away from both my workbench and my sleeping area. While the unit is...
Hello,
I am aware that the workflow of 3D printing involves the following steps:
1) Design the part using CAD and saving it as a .stl file.
2) Import the stl file into a slicing software to be converted to a G-code file
3) Load and run the G-code file on the 3D printer
It is simple and safe to...
Hello,
I understand that CAD models (stl files) suitable for 3D printing must be "watertight" and not leaky in the polygon mesh. By analogy, if we filled the model with water, the water would not leak...This concept of watertightness means that there are no unintentional holes between the...
I'm able to send these ZPL files to my 600dpi industrial Zebra printer using their Zebra Setup Utilities program, but I'm not understanding yet how to send the files to the label printer from my Tcl/Tk Mfg test program.

Hello,
When creating a curved object in Tinkercad, something like a sphere, the spheres' surface does not look very smooth but rather meshy under close inspection. Will the 3D printed version of that sphere designed in Tinkercad have a smoother surface than the meshy surface it has in the...
Hello,
The first step in 3D printing is the generation of a 3D model using a CAD software. But to be able to print the object, the CAD software is not enough, even if the file is saved in .stl or .obj format, correct? Another software, called the slicer, must then receive the 3D modeling file...
I am having an issue with MCNP6. When I run a simulation an output file is created, but not a mctal file. This behavior started after getting the following error

Hi, so earlier this week I was given a physics research project for over the summer- I naturally thought to do 3D printing as I have a printer at home. Basically, I’ve got the general idea nailed and I’ve done a fair amount of writing for this, but I need specific physics concepts/ideas or at...
I may be known on the EE side of PF as someone who hates waste and doesn’t like to throw away perfectly good machines; I like to resurrect faulty gear. This Dell printer was thrown away for want of a touch or two of solder, and works just fine. Do I really need to buy a whole new printer?

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype...
I am trying to assemble an optical tweezers setup and was thinking if it is realistic to assemble an optical tweezers setup using 3D printed parts? Also can DMD (Digital Micromirror Device) be used instead of SLM to manipulate the beam and generate multiple traps?
Browns, Reds, and Blues have been 3D printed (video here) by making very tiny shapes similar to those that underlie the iridescence phenomena.
This kind of coloration is in some ways similar to the another favorite of mine (which I would call a structural non-color): Vantablack (Vertically...
I have a design I want to 3D print. It's tiny, less than 1 inch, and has more than one fitted, moveable part.
