3D Printing 101: Part 2a: Delta Robot Mechanics

Apr 4, 2013   //   by Michael Hackney   //   3D Printing, Beginner, Blog, DIY CNC  //  1 Comment

In my earlier post this week on 3D printer Mechanics, I focused on the more traditional Cartesian printer geometry. I closed the post with a mention that I’d follow-up with a post on a really exciting new development in 3D printer mechanics – the delta robot printer.
A Little Background
According to Wikipedia, a delta…

3D Printing 101: Part 2: Mechanics

Apr 2, 2013   //   by Michael Hackney   //   3D Printing, Beginner, Blog, DIY CNC, Guest-Post  //  5 Comments

In this installment of 3D Printing 101 I am going to look at the mechanical aspect of a typical 3D printer. Before I jump in, I should say that there are many different additive manufacturing technologies (i.e. 3D printers) but this series will focus on plastic filament extrusion printers that are the most familiar…

Our First LinuxCNC Post for G-Wizard Editor

Apr 1, 2013   //   by Bob Warfield   //   Blog, DIY CNC, GCode, Software  //  No Comments

I just uploaded our first LinuxCNC milling and turning posts for G-Wizard Editor.  It’s a modest start, but we’ll build on this initial version.  The most important LinuxCNC feature we’ve added support for in the Editor are named parameters.
In LinuxCNC, you can write:
instead of:
Much easier to read than the numeric…

3D Printing 101: Part 1: 3D Printer Basics

Mar 25, 2013   //   by Michael Hackney   //   3D Printing, Beginner, Blog, DIY CNC, Guest-Post, Techniques  //  4 Comments

Since the CNCCookbook Blog is frequented by CNC machinists, I thought it would be useful to provide an overview on 3D printing from the perspective of someone familiar with CNC machining. I have four parts planned, and in this first part I’ll present a little history, describe why I (and many others) believe 3D printing…

Introducing Michael Hackney: Our New 3D Printing Guru

CNC Fly Fishing Reel

I’m very pleased to announce that Michael Hackney will be contributing to the CNCCookbook blog on a long-term basis every week with new articles about 3D printing.  I’ve known Michael for quite some time and enjoyed his work, so when I heard he was going big into 3D printing I didn’t waste a minute inviting…

Moedls: An Inexpensive 3D Scanner on Kickstarter

Mar 18, 2013   //   by Bob Warfield   //   3D Printing, Blog, Cool, DIY CNC, Products  //  1 Comment

I just signed up for Moedls, which is an inexpensive 3D Scanner project on Kickstarter.  It uses a turntable, a red laser, a green laser, and your phone’s camera to generate a 3D model of whatever you put on the 9″ turntable.  Cost to buy in early is as low as $199.  I went for…

What Now: My CNC Won’t Go Slow Enough or Fast Enough?

Mar 15, 2013   //   by Bob Warfield   //   Beginner, Blog, CNC Router, DIY CNC, Software, Techniques  //  No Comments

It takes a complex bunch of math to properly calculate Feeds and Speeds under all conditions and to get anywhere close to good answers.  There is a whole lot more to it than the basic equations everyone learns that claim to relate surface speed, chipload, rpms, feedrates and the like.  Unfortunately, those equations work reasonably…

Check Out Our New 3D Printing Category

Mar 12, 2013   //   by Bob Warfield   //   3D Printing, Blog, Cool, DIY CNC  //  No Comments

I’ve just added another category to our blog:  3D Printing.  Categories are a way for you to dial in a bunch of articles that all share a common theme.  We range pretty far and wide here on CNCCookbook, so it is sometimes helpful to be able to focus in on one category or another.  You’ll…

What If CNC Machines Could Cook? Digital Gastronomy

Dec 24, 2012   //   by Bob Warfield   //   3D Printing, Blog, Cool, DIY CNC  //  1 Comment

What if CNC machines could cook?
I’m not sure what took me down this odd path, other than that I recently made up a batch of Texas Chili Fudge and a batch of Peppermint Bark for a Christmas Eve Party.  I have been dimly aware of some CNC cake decorating projects, and I confess to…

Amazing Shopmade Plasma Table

Nov 12, 2012   //   by Bob Warfield   //   Blog, CNC Projects, Cool, DIY CNC  //  No Comments

This plasma table from CNCZone is probably the most impressive table I have yet come across:

It’s a big beast. The gantry is mounted on the long axis so that when it is slid out of the way, access to the table with a full sheet of material is easy.

They had the various parts…

Combined Coolant Ring and High Speed Engraving Spindle Using G-Wizard in a High School Shop

Coolant ring and high speed engraving spindle

We have a large following with High School and College machine shops across the world.  Both G-Wizard Calculator and G-Wizard Editor make Feeds and Speeds and G-Code a lot easier for students and improve their chances for success on their projects.  We offer an educational discount to such institutions (inquire for more information) because we…

Check Out Our New High Resolution DLP 3D Printer Page

Sep 11, 2012   //   by Bob Warfield   //   3D Printing, Blog, CNC Projects, Cool, DIY CNC, Products  //  No Comments

I’m very interested in High Resolution 3D Printers based on DLP (Digital Light Projectors), so I created a page for them.  These printers are different than the normal fused-filament 3D printers.  They’re capable of printing faster and of creating much higher resolution output.  “How much higher resolution?” you ask.  Check it out:

Now that’s High…

MIT Students Create Hand-Held CNC Router: You Gotta See This!

Every now and then you see one of those inventions or products that makes you do a total double take because you realize they are game changers.

Three MIT students,  Ilan E. Moyer, Alec Rivers, Frédo Durand (left to right in the picture), have created a game changer for CNC Routing and woodworking.  Their invention…

Better Way Covers for RF-45 Mills

Aug 5, 2012   //   by Bob Warfield   //   Blog, CNC Projects, DIY CNC  //  3 Comments
Way Cover Parts

I spent a couple hours recently replacing the way covers on my Industrial Hobbies RF-45 mill.  The ones I have seen on most RF-45’s are pretty low quality and not very durable.  I had been getting by with some magnetically mounted covers, but wanted to get back to something more secure and trouble free before…

Using a 3D Printer to Machine an AR-15 Lower Receiver

Jul 28, 2012   //   by Bob Warfield   //   Blog, Cool, DIY CNC, Techniques  //  1 Comment
3D Printed AR-15 Lower Receiver

Here is a surprising find: someone has now 3D printed an AR-15 lower receiver and successfully test fired the weapon:

World’s first 3D printed firearm…
Here’s a lower receiver, the part that was 3D printed, for those not familiar with this firearm:

The most common 3D printing processes and the one used in this case…
