Most inexpensive 3D printers use a type of lead screw to move some part of the printer in the vertical direction.

Mastering Ball Screws

A motor turns a threaded rod and that causes a nut to go up or down. The printer part rides on the nut. This works well, but it is slower than other drive mechanisms (which is why you don’t often see them on the horizontal parts of a printer). Some cheap printers use common threaded rod, which is convenient, but prone to bad behavior since the rods are not always straight, the threads are subject to backlash, and the tolerances are not always the best. More sophisticated printers use ACME threaded rod or trapezoidal threaded rods. However, when lead screws aren’t good enough, mechanical designers turn to ball screws. Misumi recently posted a few blog articles about ball screws.

In general, The Misumi catalog, by the way, is a marvel of mechanical engineering toys. Kossel Clear Delta Arm Crash Sensor by lboucher. Hi All This simple hack uses some limit switches to monitor the arms on a delta printer.

Kossel Clear Delta Arm Crash Sensor by lboucher

Should the print head ever crash for whatever reason, the printer would pause, instead of bashing the arms around for hours. Only had 2 crashes in 1.5 years, 1 i think was a power glitch, and the latest was the wires catching on the print itself. Fixed the wires by attaching them to one of the arms via rubber bands. The switches hook in electrically, by simply passing the filament sensor signal through each switch. Sonic 3D Printer Auto Bed Leveling Makes a Swoosh. 3D Printering: the final frontier.

Sonic 3D Printer Auto Bed Leveling Makes a Swoosh

These are the voyages of another 3D printer hack. Its mission: to explore strange new ways of leveling a print bed. So far, we’ve had servo probes, Allen key probes, Z-sled probes, inductive and capacitive contactless switches, just to name a few. 3D Printer Error Detection – Chris Barr Builds. I’ve been playing around with magnetic encoders a lot lately in the hopes of getting some sort of error-detection system up and running.

I think I’ve finally made some headway on it. I’ll start off with the video of where I’ve gotten too. It’s not much, but I think this system is worth exploring further. Filament Width Sensor Prototype Version 3 by flipper. This is a prototype for an optical sensor that measures the width of plastic filament in real time as it goes into a 3D printer or a filament extruder.

Filament Width Sensor Prototype Version 3 by flipper

It is prototype #3 (other 2 are on Thingiverse as well ). The idea is that with a real-time width measurement the 3D printer could compensate the extruded flow for changes in filament width. Also if there is variation between spools of filament, there is no need to calibrate for that when slicing. The g-code is independent of the filament diameter. For filament extruders, the measured width can be used as feedback in the extrusion process.This version includes a custom designed pc board as well as a housing. Cohesion3D. New Part Day: Smoothie For RAMPS. When it comes to 3D printer controllers, there are two main schools of thought.

New Part Day: Smoothie For RAMPS

The first group is RAMPS or RAMBo which are respectively a 3D printer controller ‘shield’ for the Arduino Mega and a stand-alone controller board. These boards have been the standard for DIY 3D printers for a very long time, and are the brains for quite a few printers from the biggest manufacturers. The other school of thought trundles down the path of ARM, with the most popular boards running the Smoothie firmware. New Part Day: Smoothie For RAMPS.

I haven't used the Duet 0.6 or any of the other iterations. Hardware Capabilities The Duet has 96KB RAM, runs at 84MHz, and has five stepper axes (expandable to 9). You can drive up to six extruders.Smoothie has 64KB RAM, runs at 120MHz, and has five stepper axes. There are no official or third-party expansion boards, so you're limited to two extruders max.Both boards have USB and Ethernet connectivity.

How to Build a 3D Printer: Getting Started Guide and Tips

The process of building your own printer can be a bit daunting to some people, especially with so many choices out there. This article will compare different designs and parts and give tips on construction that will hopefully layout the tools and knowledge you need to know on how to build a 3D printer. Getting Started The first thing to do once you decide to build a printer is to decide what type of printer you want to build.

TweakTown's Guide to 3D Printing: Part 1 - What makes up a 3D Printer? 3D printing is all the rage at the moment. The ability to design or download an object and watch it form in front of your eyes is a very appealing thing to a lot of people. Up until a few years ago, printing physical objects in the third dimension was something that was just out of reach for the average consumer, with entry-level commercial machines costing tens of thousands of dollars.

One day in 2005 a professor at the University of Bath in the UK decided to change the 3D printing world forever. Dr. Adrian Bowyer, a senior lecturer in mechanical engineering at the University of Bath decided to tackle the problem of an affordable and hobby sized 3D printer. In this guide I am going to attempt to help you make sense of it all and hopefully guide you towards purchasing the best 3D printer that suits your needs.

If you are reading this article that means that you’ve probably decided to join the community of 3d printing enthusiasts and find out more about 3d printers, or maybe you have already got some experience in it and are ready to try to create your own 3d printer from scratch.

In this article you will find general understanding how 3D printers can be built as well as links to really useful resources where you can find more detailed information with step-by-step description. Currently there is a big variety of 3d printers in the Internet that already assembled and are ready to print right after you unpack them from a box, of course you also need to buy a 3d printer filament for it. Do not forget that not all 3d printers can use the same filament types, so please read the instruction before you purchase it.

By Kalani Kirk Hausman, Richard Horne RepRap 3D printers use the popular open-source Arduino microcontrollers along with stepper motor controllers and motors and sensors for movement control. Some custom 3D printer boards integrate the Arduino’s functions with the related items typically found on a 3D printing “shield” that attaches to the basic format.
