10€ closed loop control 3D printer from old inkjet printers – Michele Lizzit. Inkjet printers are incredibly cheap and most printers do not last more that a few years before the inkjet nozzle breaks or the paper loading mechanism starts to fail; as a consequence lots of broken inkjet printers can be easily obtained in junkyards or from friends. Each inkjet printer has 1 axis that is very similar to what a 3D printer needs with only one difference: most inkjets do not use stepper motors anymore.
Inkjet printers usually work by using a cheaper DC motor coupled with a linear optical encoder, the DC motor runs at full speed while the data from the encoder is interpolated and used to trigger the inkjet nozzles. What I did is to build a 10€ 3D printer by disassembling 3 inkjet printers and an old scanner. The only parts I could not source by disassembling printers are an hotend (4€) and part of the electronics (~6€). I have written a firmware for the Atmega328 and I was able to obtain a precision of about 33µm on each axis.
This is the result: Then attach the axis together: Image to Lithophane.

The story of Cupid and Psyche was a popular artistic choice in the neoclassical period. Canova produced many versions of the theme; most were of terracotta, but he also sculpted some beautiful marble groups, two of which are in the Louvre: Cupid and Psyche standing, and Psyche Revived by Cupid's Kiss. The figures of Cupid and Psyche are standing, Cupid completely naked, Psyche modestly draped, he with his arm around her shoulders. She raises his left hand with her own, to place a butterfly on his palm.
The butterfly symbolizes her soul, which she offers in all innocence to Cupid. The wandering of the soul was a concept of the Neo-platonic philosophy to which Canova adhered. The love between the two characters is represented simply, somewhat naively, by their contemplation of the butterfly. The group stands on a high cylindrical pedestal decorated with garlands of flowers and a butterfly. This object is part of "Scan The World". Scanned : Photogrammetry (Processed using Agisoft PhotoScan) How to build a simple, cheap enclosure for your 3D printer. Maybe you have already seen some of those fancy enclosures people build for their printers.
How do they work? And do they work? Today, we will shed some light on this matter! Plus, we are going to dive into patent wars and explain why not all printers come with an enclosure. To top things off, we will even give you a full guide with information on how to build an enclosure for your own printer. But first, let’s start with the fundamental question: what is it good for?
Stable printing environment – Drafts can negatively impact your print. However, if you’re not printing with ABS or other high-temperature filaments that suffer from warping, you won’t see much of a difference. Why aren’t all the printers on the market enclosed by default? There are two factors here – price and patents. It was only after these key patents expired in 2009 (20 years after application) that the RepRap movement started. Another obstacle is the price. How hot should the enclosure be and can the PSU stay inside? MakerBot account. The 3D Printed Marble Machine #3 by Tulio. Search free 3d models for 3d printing & 3d design - STLFinder.

OpenSCAD User Manual/The OpenSCAD Language Introduction[edit] OpenSCAD is a 2D/3D and solid modeling program which is based on a Functional programming language used to create models that are previewed on the screen, and rendered into 3D mesh which allows the model to be exported in a variety of 2D/3D file formats. A script in the OpenSCAD language is used to create 2D or 3D models. Object(); variable = value; operator() action(); operator() { action(); action(); } operator() operator() { action(); action(); } operator() { operator() action(); operator() { action(); action(); } } Objects Objects are the building blocks for models, created by 2D and 3D primitives.
Actions Action statements include creating objects using primitives and assigning values to variables. Mandelbrot Set by MaskedRetriever. Sign in to your Microsoft account.

From Math Images 3-D Pythagorean Tree The three-dimensional Pythagorean tree is a fractal composed of cubes whose side lengths are structured according to the Pythagorean theorem. It is called a "tree" because, after a few iterations, the fractal acquires a tree-like shape. The three-dimensional Pythagorean tree may be easier to understand if we start from the two-dimensional case. The Pythagorean tree is a fractal, so we build it by starting with a base case and continually applying a rule to it. The base case is a square. The rule we apply to each square is that one of its sides serves as the hypotenuse of a right triangle, the legs of which are the sides of two new squares. On this page, we will specifically consider sides which form isosceles right triangles, so the iterations are symmetrical. The three-dimensional case is simply the two-dimensional case extruded, or "pulled out". Figure 1Extrusion from the two-dimensional to the three-dimensional Pythagorean tree.
