101 Mendels


His first design is way more sophisticated that anything I have managed so far. It is testimony to the reliability of the mechanical design and if anything, the quality of the parts is getting better as I tweak the settings.

Random thoughts on hot-end design

RepRap Blog

I spent some time modding the bfb hot-end. Originally the hot end is very sturdy but with extremely soft filament (soft-abs from orbi for example) it is not able to print at low speeds (0.25mm layer 16mm/sec was on the limit, working but not consistent, 0.15mm layer 16mm/sec killed it).

James Cameron Uses 3D Printing

On Tuesday of this week, I listened to inspiring anecdotes from film maker James Cameron, the producer of Avatar , at SolidWorks World 2010 in Anaheim, California. SolidWorks co-founder Jon Hirschtick interviewed him in front of more than 5,000 engineers, designers, and others interested in SolidWorks. During his interview with Hirschtick, he explained how he and his team designed and built a 12.7

Changing a Name

Wohlers Talk

They include the development of standards around test methods, processes, materials, and design (including data/file formats). Old habits die slowly. Case in point: Transitioning to the term additive manufacturing. Thats now the official name of what some refer to as rapid prototyping, freeform fabrication, and a host of other names. Additive manufacturing (AM) is the official name … according to who? ASTM International F42 Committee on Additive Manufacturing Technologies.

3D Printer from HP

Wohlers Talk

HP will initially target mechanical designers in France, Germany, Italy, Spain, and the UK with the new product. In January, it was announced that Stratasys would manufacture a 3D printer for Hewlett-Packard, a product that would carry the HP brand. The announcement got a lot of attention because few large, well-known companies have entered this business. If the roll-out goes well, HP expects to sell the product in other countries.

U.S. Manufacturing in the Future

Wohlers Talk

Additive manufacturing is about flexibility and relatively low volumes, while IM is about locking in on a design and producing relatively high volumes. An estimated 1,2001,300 injection molding machines shipped in the U.S. in 2009, according to editor Bill Bregar in the December 7, 2009 issue of Plastics News. Contrast this with an estimated 1,886 additive manufacturing (AM) systems sold in 2008 in the U.S. and 5,060 worldwide, according to Wohlers Report 2009.

Story of simpler Mendel: Y and Z axes

RepRap Blog

In testing so far, I can find only positive things to say about it vs the regular timing belt design. If you don''t wish to try it, you can use older Z axis, the design is still compatible! You cant achieve this with older design.

Some corners like it hot


When I design my own parts I round the corners, where possible, to prevent such problems. Large objects with sharp corners, such as the Mendel z-leadscrew-base, produce enough stress to form a blister in the PET tape on my heated bed. These can only be flattened again by pricking the tape.

Making Mendel


I made a much simpler design with drill centres on it. They seem to have sufficient repeatability and certainly will when I replace the electronics with my new design, which will know the motor phase, reducing the uncertainty by a factor of 32.

Introducing the Nothing Labs Electronic Cloud Chamber

Nothing Labs

As far as I can tell - this is the first cloud chamber design that uses electronic / peltier cooling which doesn''t need external secondary cooling (like cold water). I came up with this cloud chamber in early 2010 - and promptly published most of my findings online.

Story of simpler Mendel: PLA bushings and X-axis

RepRap Blog

2 months ago I started process of simplifying Mendel design, so far I was able to reduce parts count, assembly time, use of vitamins and also price. I also designed all parts to be able to change the bushings when they worn-out. Its really easy and simple design.

Hot bed


Of course mains on a moving table is not the safest design. Making a heated bed to combat warping has been on my "to do" list for a long time. In fact I ordered the materials more than a year ago. My plan was to use an aluminium plate with many small power resistors screwed on the back.

A Smarter Approach to Infill

RepRap Blog

The issue with this is that with present extruder designs, and even with reversing, we still get some ooze that makes a bit of a mess. As is often the case, I had my Mendel running a week or two ago, and I was sat mesmerised for far too long watching it work.

Yet Another Geared Extruder

I wanted to design a single extruder driver that could Be bolted to the X carriage of Mendel and run as a normal extruder, Be mounted somewhere at the side and drive a Bowden extruder, and Be mounted somewhere at the side and drive a Bowden paste extruder, as outlined here.

Introduction to Additive (Rapid) Manufacturing,Prototyping & Tooling

RPM Tools

The use of additive manufacturing for rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software, transforms them into thin, virtual, horizontal cross-sections and then creates successive layers until the model is complete.



My contribution to the design is the box. The lids had to be printed hollow side down because of the raised design on top. My wife has assembled her own Christmas crackers from kits in recent years. She puts in much better gifts than even the more expensive commercial ones contain.

Reprapping two materials into one object

Mendel & multiple materials

I once had a design that ended up having a maximum build height of 2cm.very practical:D). Moreover, its more difficult to have a head changer for extruders whose designs are still in the early stages (such as the paste extruder).

Overhang support and PCBs

The same pen plotter could be used with an etch-resist pen to make PCBs, such as these designed to make reprappable electronics simple. With a lot of work going on on putting pen-plotters in RepRaps for PCBs (and other things), it seemed to me that we might re-visit an old idea.



Brian Reifsnyder asked for volunteers to test his hybrid PEEK and PTFE insulator design, so I used it for the hot part of my Mendel extruder to start with. The drive mechanism is Wade''s design. Brian has added a circlip to the design to solve the problem.

Tiny ball-chain gears

The gears themselves are designed to be "spiky", but the vaguearities of the printing and rendering process lop the spikes off and leave enough by accident to produce a functioning gear! There are knock-on effects on the bed design and X Carriage which I''m still working around.

Bowden Paste Extruder

Slice and Dice 0.1

While that is very handy if you need a lot of a thing, if you''re just trying to develop a part you take 6-8 times longer to print your part and find the errors in the design. What that means is that a decent design is going to generate many, many gigabytes of images.

Paste Extruder - The first test

The real beauty of Zach''s design is a relief valve that is able to exhaust the high pressure air from the syringe. The main difference between this design and others is in the valve. Secondly, the frostruder design has the high pressure acting directly on the paste.

Stepping up to the mark


Neither of us could remember what the old clip looked like so I designed a simple one from scratch. My wife is a very measured person. As well as watching how much power we using she likes to count her footsteps with a pedometer to check if she is getting here daily quota of 10,000.

Extruder broke already


I would need a working extruder to make the new bracket of course, so I decided to bodge the existing design. I think it would work fine with an extruder designed for 2mm filament. Well my best attempt at making a reliable extruder again resulted in one that only lasted a few weeks!
