Sailfish Firmware for faster MakerBots

Jetty's Sailfish firmware brings better performance to most of MakerBot 3d printers. 



From their thingiverse page :
"A Sailfish is faster than a Marlin".

Sailfish is the next generation of the Jetty Firmware. It's faster and has better print quality.

Supports: Replicator 1, ThingOMatic and Cupcake (TBA)

Firmware Manual: wiki.makerbot.com/jetty-firmware

This firmware contains many new features, some of which are: better acceleration, ditto printing, Pause@ZPos, SF50 Volumetric 5D printing.

Feature list: wiki.makerbot.com/jetty-firmware#toc3

Requirements: wiki.makerbot.com/sailfish-firmware-installation-guide
Be sure to check their instruction before installing, but the procedure should be very easy.

Rostock MAX

Currently on Indiegogo




From their IndieGoGo page:

Advantages of the Delta Arm design:

  • MUCH faster Z axiz movement.  A traditional 3D pritner design uses threaded rods or acme screws.  These severely limit the Z axis speeds to about 200-400 mm/min speeds.  With the Rostock MAX, we have the same speed in X/Y as we do in the Z, which is up to 40000 mm/min.  Holy Cow right! 
  • Counter acting forces of movement.  With a traditional pritner again, you have a carriage moving left/right or front/back, and it has to overcome the weight of that movement to reverse it's direction.  We use accelaration to tune the motors DOWN to slow the speeds of the carriage when it's near the end of a move so it doesn't "whip" or chatter, when changing directions.  With the MAX, all three carriages have to move together to make coordinated motion, so if one arm has to go up, the other two have to go down, and this cnacels out a huge amount of the inertia in the movement at the head, so we can tune the motor to a much higher rate, increasing the speed.
  • Circular motion is smoother by default with the Rostock MAX.  The delta arms also have a unique feature, SUPER ROUND CIRLCES!  Now, yes, you can have the same smooth circles with a standard printer, however, you have to work to get it to make those circles very round.  The reason is you have two straight lines, one in the X and one in the Y, and you have to vary those two lines to make a circle.  Any backlash in the belts/pulleys etc... will cause the circles to come out egg shaped at best.  With the MAX, circles are more true, becuase any backlash that could exist is cancelled out by the fact that the platform "hangs" from the arms, and gravity takes care of the rest.  There are other reasons too, such as that every single move sent to the printer is split into 200 seperate movements.

Features:


  • Approximate 10"+ Diameter x 13" + High build volume
  • Sturdy design using bolted together parts
  • Precision laser cut, CNC and injection molded parts
  • Designed for english OR metric hardware
  • Windows, MAC, and Linux compatible with OS software
  • Uses UltiMachine RAMBo electronics
  • Uses Standard NEMA 17 motors and GT2 timing belt
  • 15 Tooth motor pulleys
  • Filament is held by the machine, no more tangled spools on the floor
  • Wide open access to the build area, easy to get at parts
  • Unique design lends to easy modification for other uses
  We are looking into other "tool heads" to attach to the platform.  Some easy to convert ideas are pick-and-place vacuum head for electronics board assembly, sodler paste syringes for PCB prepping, pen mount (it's the $25 perk) for plotting/drawing and even a low power laser platform should be easily adaptable.
***EDIT***
 We are also going to be using UltiMachine's new electronics boards, the RAMBo. They have the ability to run two extruders, one heated bed, and up to 5 stepper motors.  Check out theRAMBo wiki page to learn more about these really awesome 3D printer electronics from UltiMachine.  The boards have 5 allegro A4984 stepper drivers, two plugs if you ever need a dual-z motor setup etc..., 4 thermistor inputs, and so many more awesome features. 

More information about our Rostock MAX can be found online over at theRepRap project, as well as our Forum.  We will be posting build instructions, CAD files, firmware settings and more, all on ourRepRap.org Wiki Page

Filament Making Machines

Usually if you want to print something you need to have filament to feed your 3d printer. But, what if you could recycle your failed models or even recycle waste plastic and make f3d printing filament out of it? Basically suitable junk plastic is ground up, continuously pressed and melted trough extruder similar to the one on 3d printer and after cooling you get filament ready for next print job.  Currently there are two projects that I know which are developing usable technology. They are in various stages of development and availability, let's hope that this technology goes into full implementation. 


Filabot 

From filabot.com :
Filabot is a desktop extruding system, capable of grinding various types of plastics, to make spools of plastic filament for 3D printers. Not only is it user friendly, but it is also environmentally friendly. The Filabot can process things such as: milk jugs, soda bottles, various other types of plastics, and bad prints, to make new filament for a future print. Filabot will bring the real power of sustainability to 3D printing, allowing for a one stop shop to make anything.



Lyman Filament Extruder 

From http://www.thingiverse.com/thing:30642 :
The Lyman Filament Extruder is a machine that extrudes filament from pellets for use in a 3D Printer. It can extrude 1.75mm and 3mm filament with easy nozzle exchange. The material cost is about $250.
On their thingiverse page there are plans, files and guides available.

Afinia H-series 3d printer






Youtube user maxamillionschnell has extensive video demonstrations of the Afinia (he disabled embedding for most of the videos), here is the mechanical overview:



There is few data available on Afinia h-series, so if anybody knows more or has any experience, write it in comments or message me.

Afinia is also running a simple contest where you can win their printer, entries will be accepted from October 1 through Dec 31, 2012:

Maker Movement to New Industrial Revolution

Must-watch for anyone interested in technology, economics and 3d printing.



Interview with Bre Pettis of MakerBot Industries

He talks about how they developed the business, about cheep Chinese clones from AliBaba, future, why NASA uses MakerBot printers and other interesting stuff ... great interview by tested.com
