Main features:
Wire management
We know you do not like messy wiring. Neither do we. That was the reason why we spent tons of time and effort to manage those wires. We even went back to change the machine design multiple times in order to get a better routing option. Finally, we worked out a solution which can meet our standard to be part of a "neat machine". Hope you will like it as we do.

HBP Corner
No binder clips, please.
Binder clips have become the typical solution in most desktop 3D printers to hold its print surface to the build platform. Although they work fine for the purpose of holding the print surface, they waste otherwise usable print area on the edges,  interfere with the extruder nozzle, and give an "unfinished" look to your printer. The Artifex 3D Printer comes with newly designed HBP (Heated Build Platform) corners, which have securing slots to hold the glass plate and the heat spreader in place. The HBP corners can be easily slided out to release the glass top if you need to access the glass for maintenance.

Adjustable Y-axis Carriage
Less vibration means faster and quieter printing
In the original MendelMax 2.0 design, large vibration was observed at high printing speed. Such vibration created lots of noise and also caused quality problems in the finished parts. Majority of such vibration was caused by the large gap between the Y-axis rail and its catriages. The 3DMakerWorld Artifex 3D Printer uses upgraded Y-axis catriages with adjustable clearance capability. By reducing the gap between the Y-axis rail and the catriages, the 3DMakerWorld Artifex 3D Printer can achieve quiet and high-quality printing even at high speed.

Three-point bed leveling system
If you have ever tried both three-point and four-point bed leveling systems, you certainly know how much easier the bed leveling could be with a three-point leveling system. Yes, the 3DMakerWorld Artifex 3D Printer comes with a three-point bed leveling system in place to ease the leveling process.

Adjustable Z-Axis End-Stop Trigger
Adjustable Z-axis zeroing
As you continue advancing into the world of 3D printing, you will find the need to fine tune the distance between the extruder nozzle and the print surface. Such process is called Z-axis zeroing. The Artifex 3D Printer provides the adjustable Z-axis zeroing capability. It uses an adjustable Z-axis end-stop trigger to precisely adjust the nozzle height without messing up the bed level.

HBP cable strain relief
The HBP heater moves along the Y-axis with the build platform. The joint between the cable of HBP heater and the build platform is often a weak point due to the strain applied during continuous movement. A strain relief is built into the Artifex 3D Printer to secure and support the cable of HBP heater.

Enclosed electronics with dedicated cooling fan
The electronics board on the Artifex 3D Printer is completely enclosed from top to bottom for safe operation and easy maintainence. The electronics case also contains a dedicated cooling fan to cool off the electronic components during printing.

24V Power Supply with Rear Panel
24V power supply with convenient power switch
The 3DMakerWorld Artifex 3D Printer uses a 24V power supply to provide better heating capability on heated bed, and to improve motor performance at high printing speed. For the purpose of safety and aesthetics, all wire connectors are enclosed by top/bottom covers and back panel. An easy-reach power switch is installed on the power panel to switch on and off the power to the printer conveniently.

Appropedia MOST Delta 3d printer

Another Rostock derived Delta 3d printer with very detailed build guide.

From project page:
The MOST Delta printer is RepRap derived from the Rostock printer with the following design goals:
  • Simple build process
  • Safe to operate
  • True to RepRap
  • Maximize value
  • Maximize rigidity
  • Aesthetically pleasing (or at least neutral)
  • All PLA printed parts
  • Excellent print performance
The design utilizes plywood linking boards cut to a length that yields a desired printer radius when attached to the printed apexes. This simplifies assembly while helping to assure that printer dimensions are fixed, stable and reasonably well known. It also improves flexibility as the print area in the x-y plane can be changed simply by replacing the boards with boards of a different length. The delta design is inherently simpler to assemble as compared to virtually all it's Cartesian counterparts; this design can easily be built within a day by one person having properly prepared parts.
The design uses a 12v 5A power brick instead of the popular 12v power supplies having mains connections relatively exposed, a relative safety issue, particularly when children are present. The power supply is roughly equivalent to those found with many inkjet printers.
As many printed parts are used in the design as are practical, including printed pulleys. This in large part drove the decision to use open T5 timing belts for the drive, which also makes the design more flexible as the length of the guide rods doesn't need to be based upon the length of an off-the-shelf continuous belt.
Cost considerations drove decisions regarding everything from printer capabilities (as shown, prints PLA only) to guide rod material and length (two six foot lengths of 8mm drill steel are required, producing no waste). A Melzi controller is used as it provides all the necessary features as well as SD card support and reasonable expansion options. The power supply is a fraction of the cost of that required for powering a heated bed.
Printed apexes are very robust, probably overkill, and along with the plywood components and ample fasteners produce a very rigid structure. The printer has proven to transport very well (and can even be seat belted) with no adjustment needed prior to printing at its destination.
The end effector is actively cooled allowing for a unitized effector/hot end mount printed in PLA. The hot end is recessed within the end effector, maximizing z-axis travel and also providing for some print cooling.
Printing performance has been very good as has been the experience of printing with this design. Much less user intervention has been required as compared to experience with Cartesian RepRaps.
Printer capabilities/statistics
  • Print media: PLA only (heated bed can be added, expanding media options)
  • Filament diameter: 1.75mm
  • Nozzle diameter: 0.5mm (can be changed)
  • Print volume: ~250mm radius (with 240mm long linking boards) 270mm high
  • Melzi print controller w/ integrated SD card reader
  • Airtripper's Bowden Extruder

Fully 3d printed speaker from Cornell's Creative Machines Lab

Speaker was fully 3d printed including metal coil at Cornell's Creative Machines Lab by Apoorva, Robert MacCurdy and Hod Lipson. To make it printable, the electronic components are made with two customizable 3D printers: a special silver ink extrusion is used for the coil and a viscous blend of strontium ferrite is used for the magnet.
It's the future people. We just need to get more synergy and merging of 3d printed plastic and 3d printed electronics.
I hope that projects that could empower every maker to print similar speakers like Spoolhead wire embedding 3d printhead RepRap will be revived and improved.

Geoweaver walking hexabot 3d printer

Geoweaver is hexabot walking robot made from lasercut and 3d printed parts that has glue gun extruder attached for printing on walking surface. IT IS A FREAKING WALKING SPIDER ROBOT 3D PRINTER!!!!! AND YOU CAN BUILD IT YOURSELF!!!
very cool ...
It is not highest quality of 3d print and it has some limitations, but this concept could be developed in the future. You could have several in your home that could print different furniture and recycle it every day ... or swarms printing buildings ...

Very detailed information with full build instructions and all the files:

From Instructables description:

Geoweaver is a student designed robot created in the Creative Architecture Machines advanced options studio at the California College of the Arts (CCA) in San Francisco, California, taught by Jason Kelly Johnson of Future Cities Lab and Michael Shiloh. The design is based on a 12-servo hexapod with a glue gun extruder attached, and is the culmination of about 60 days of research and prototyping. Although the robot's official name is Geoweaver, it also goes by many aliases: Servo Killer, Eater of Shields, Melter of Wires, and Destroyer of Regulators, among many others. It is a very difficult and delicate machine, and is not a project to be tackled for the faint of heart.
But if you do take it upon yourself to accept it's challenges, it's rewards are great: it is a six-legged, walking 3D printer. The center mechanism uses two servos to control the pendulum-like extruder head, allowing it to cover a basic XY plane (though curved to the surface of a sphere, see video above), and one servo for the extrusion gear that forces the glue-sticks through the "print head." All of this can be controlled through the software Rhino 5, with the plug-ins Grasshopper and Firefly

it was designed and made by Student Team: Jia Wu, Jeffrey M. Maeshiro, Mary H. Sek at CCA - California College of the Arts Architecture Advanced Options Studio, Prof. Jason Kelly Johnson with Michael Shiloh


As several commentators on G+ and Reddit noted, they are like puppies pooping ... ;-)

Update (22.2.2014.):

here is a video of small robotic "ants" or "termites" building structures. If you combine these two technologies, some interesting synergies could emerge.

Update from HYREL 3D

From video description:
Just in time for the 2013 Holidays, HYREL 3D changes the economics of 3D printing with a single, affordable machine.
Whether one of HYREL's Engines or Systems, all are able to fabricate multiple parts simultaneously.

What this means to you:
If it currently takes four hours for your 3D printer to print / fabricate a single part and you need four of the same parts, it will take at least 16 hours total with a single machine.
With a single HYREL Engine or System, your capacity to fabricate parts simultaneously on the same machine opens up the bottleneck, saves you time and valuable shop space.
So, if you need two, three, or four fabricated parts... or if you need a small production run of parts...
... or if you'd like to mix in other materials with our different extruder heads -- you can do it all on your HYREL.
Other Materials include:
Sugru, Clay, Porcelain, Precious Metal Clay (PMC), Silicone RTV, Play-Doh, Plasticines... and coming soon, Wax, Chocolate, Cheese, Peanut Butter... etc.
For the material in the video, we used four colors of ABS. Each of the Mk1 Extruders in the video have been tested and verified to fabricate parts with the following types of filament: ABS, PLA, Nylon, PET, & Rubber. More filaments are currently being tested and more will be certified as 3D printable with the Mk1s in early 2014.

Cherry Pi Delta DIY 3D Printer by AndyCart

Deltas are everywhere ... here is new one by AndyCart ...

From Thingiverse description:
This is my own variant of a variety of 3D printer designs available. I have used ideas from Kossel, Delta Pi, 3DR and, of course, Rostock. Many thanks to the designers of those machines for their brilliant ideas that I have shamelessly 'Cherry Picked' hence the name of my design!
The rods on my printer are 277mm from steel ball centre to centre. The towers are 800mm Bosch/Rexroth aluminium extrusion and the base frame extrusions are 250mm long as are, obviously, the top frame extrusions. You need nine in all.
The bearing carriers use 6 623 10mm x 4mm x 3mm bearings and slide directly on the extrusion. Nut traps for M3 nuts are included in the carrier. The rods connect to the carrier with a plate that fastens with 3 M3 bolts, again nut traps are included. The rod carriers and the effector plate hold 10mm x 5mm countersunk, cylindrical rare earth magnets and my rod end balls are 8mm diameter. My rods are 5mm carbon tube but you could use 6mm aluminium. My rod end balls have a 10mm M5 threaded rod and are the type used for the ends of gas struts, etc. the idea of the seperate rod carriers was to enable different rod attachment methods but the magnets and balls have worked out fine for me.

3d printable asthma inhaler

Holly from England made this 3d printable asthma inhaler. Hopefully the design will be open sourced in the future.

From source blog:

My fully functioning asthma inhaler design for my uni project is 3d printed in ABS. I tried to work my design around ergonomics:

  • The back part is completely rounded to enable it to fit in your hand more comfortably
  • Flat parts on the side add for grip along with the slightly curved in front.
  • The smaller but longer mouthpiece is so you can fit it better into the mouth to better take the medication.
  • Another feature is that it glows in the dark so you can find it quickly at night or in your bag, unfortunately due to costs, the glow in the dark ABS filament is far too expensive for me to afford.


Also, check the previous post on custom baby asthma medicine nebulizer mask:

Video of new 3d printed cruiser skateboard

From video description:
Tas Oszkay, Mo Harmon, and Jac Currie are graduate students at UCLA's school of Architecture and Urban Design who re-imagined skateboard product design using ( Solid Concepts' 3D Printing to manufacture an incredible board in one unit. Their board is an involved aesthetic dialogue between form and function. The design reveals heavy influences from the team's organic inspiration, Radiolaria. From a machining perspective, the complex mineral shell of radiolarians is nothing short of a nightmare. The patterns of the organism from under a microscope weave into each other, looking roughly similar to a dried up piece of sea reef. The team took the basic design of the silica skeletons unique to radiolarians and further complicated it through layering using CAD software.
Their board is self identified as a cruiser, meant for gracing the beach front or getting about campus. They think in the future they might look into trick boards; 3d Printing is a technology capable of being extremely light, and that would factor well into such a venture. But for now, they're experimenting with the more relaxed board.
Here is the post about first 3d printed skateboard project:

Advantages of a timing belt driven Z-axis:
Most 3D printer systems use a lead screw or a threaded rod as drive for the Z-axis. Backlash and imbalance cause errors in X- and Y-direction when moving the Z-axis. These errors are visible as vertical pattern on the printed object.
When using two timing belts as attachment for the Z-axis these errors can cleverly be avoided. Consequently the Z-axis is nearly error free, thus the layers of a printed object lie perfectly on top of each other.

There will be single and dual extruder versions, currently they are on pre-order: First delivery in February 2014.
