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? in a...

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...

I have a code that is something like this print("Gamma^",syms[i],"_",syms[j],syms[k], "=", syms[1], syms[2]**2) When I print in jupyter-lab it looks like this Gamma^ r _ theta theta = r theta**2 Gamma^ r _ phi phi = r theta**2 Gamma^ theta _ r theta = r theta**2 Gamma^ theta _ theta r = r...

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. With Google searches, I've found the ezprint option...

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 forrtl: severe <157> : program exception -access violation I restarted and didn't get the error, but now not the mctal file and I...

I want my output to read only the integers. Here's my attempt: number = int(input()) for i in range(2, number+1, 2): print(input())

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? This...

I am not sure that this is the right place to post this question, so I will be happy to let any moderator move it. (I would be less happy to find out that the question has no place in PF, but I would accept it.) I have been asked to make a list of American manufacturers of plates for...

I was reading Fundamentals of Inket Printing and it said the following: "The surface tension in a liquid causes a force to act in the plane of the free surface perpendicularly to a free edge in that surface." Can someone explain to me what this means? What's the direction of the force? I have...

Several interesting moonscape files can be downloaded from here for 3D printing.

Specialized 3D printers can now produce small optical elements: Described here. There is also a company that makes light shaping diffusers (for lamps) that control the light by controlling the interference patterns of the light due to microscopic structures on the surface of the diffuser film...

to all members of the forum. In the attached image is equation numbered 3.23 which, by the application of Euler’s Identity - called De Moivre Theorem one line below - leads to equation 3.24. Above is an a textbook frought with errors - printing ones. I would be highly appreciative of a...

Hi, Wasn't sure where to post this so thought I would post it in general. How do I avoid aliasing problems on a 600x600 DPI printer? Kind regards.

Hi PF! I am trying to import code written in Python into Latex via the "minted" package. However, I am getting the error: Package minted error: you must invoke latex with the -shell-escape flag. I tried googling help but I can't figure it out. I'm using Python 2.7 on mac OSX sierra. Any help...

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. I'd like to figure out if it's feasible before I decide whether I buy in. I don't know what software is used to make the designs. (A friend told me his printer supports .stl files) I...

This little article discusses a variety of savings GE got from using 3D printing in making a new turboprop engine. They included fewer parts (855 --> 12), subsystems (40 --> 1), and suppliers (50 --> 1).

I know that the Millennium Edition of FLP is supposed to be the most up-to-date and corrected, however, I have read (in amazon) really less than ideal reviews on how glossy the pages are, how light the printed text are, and how the texts go inside the left margin making it very difficult to...

Print either "Fruit", "Drink", or "Unknown" (followed by a newline) depending on the value of userItem. Print "Unknown" (followed by a newline) if the value of userItem does not match any of the defined options. For example, if userItem is GR_APPLES, output should be: Fruit #include <iostream>...

Is it possible to 3d print a neuronal structure with a different material than neurons that would work just like a neuron with membrane potential?

First and foremost, I apologize if this question is posted in the wrong section. I wasn't sure where to place it and figured it was at least tangentially related to math (and that the mods/admin would re-route my thread topic to a new location if appropriate :-p). On to my question...
