I was asked to do 3D printing of a pdf image from my friend. to print an image, We need to convert the image to 'svg', the vector image. convert pdf to png If we search from search engine, we can find some free converter 'from pdf to png'. ofcourse, It is better having a converter 'from pdf to svg'. but mostly that converter ask us to pay for that. so, if we want to work with free converter, we ..

We get a lot of waste when we do 3D printing. bunch of plastic waste. colorful and shapeful. here we go. my fun art

I am failing the robot test.  What? How come?  It was too difficult to pass this test. maybe I am thinking different way.  There are some vague part to select the answer boxs.  this photo is fine to decide.  but this image is problematic. Should we select the rider on the motorcycle?because rider is not a machine. I checked only the motorcycle part, not human.  Traffic lights should be only the ..

We have N consecutive natural numbers. 1, 2, 3, 4, 5, 6, . . . , 100, ...., N When N is 6, 1, 2, 3, 4, 5, 6 are the number that we have. Q1. Can you try representing these numbers using cube blocks? Yes, simply, We can make number block for each number. like this. 123456 Q2. Now, Let's try sum of those numbers using cube blocks. How would you visualize it? 1 + 2 + 3 + 4 + 5 + 6 We can combine al..

I made a tablet stand that can produce three angles. It was beautifully printed and worked well.  However, the tablet may slip from the back.slip is not happening at the moment. but to make it more stable. I wanted some solution. so,A cube block was added in the back side to prevent slipping.  and wanted to print it. but when I import 'stl' file to the slicer, error occured.  so, I brang previou..

The liquid one. pour it on. When we print an object, not always get stable result. If we miss the moment our object start detaching from the bed, we will find our object dancing on the bed with free style. Adhesives are used for emergency treatment. So which adhesive should you use? 1) Adhesion test We want to know which glue have more power of adhesion. Let's compare the adhesive strength with ..

To understand the formula, Linking a formula to a visualized image or physical object is Very helpful. For this aim, we developed 3D model. Step 01. Tinkercad modeling [Code block] Step 02. [Enjoy visualization with images] Load all pieces into the workspace. Now all the pieces stay together in Tinkercad's 3D design workplane. The images upper shows cube blocks of length 1, 2, 3, 4, and 5. On th..
