Hacking IKEA tables into 3d printer enclosure

If you want to get high quality prints you can use a printer enclosure to stabilize the temperature making it a protective isolating chamber. Stable and higher temperature can prevent warping and other heat related damage to your 3d printed object.

Here you can see how to make a simple DIY enclosure from two IKEA "Lack" tables and some acrylic panels. It makes internal temperature stable at around 40 degrees centigrade compared to 20 degrees centigrade of room temperature. It also features extractor fan for fast cooling.

Do remember that you can also make a 3d printer form IKEA furniture:

Raytheon can 3d print military missiles

One year ago I wrote a post about research on making 3d printed warheads and missiles:

http://diy3dprinting.blogspot.com/2014/07/us-military-will-3d-print-warheads-and.html

And now it is reality...

Raytheon, one of the major defense companies,  announced that it has technology to 3d print most of the rocket. Another victory for humanity. No, it's not but it will make some profit for them probably.


Here is the summary from their press release:
Researchers at Raytheon Missile Systems say they have already created nearly every component of a guided weapon using additive manufacturing, more commonly known as 3-D printing. The components include rocket engines, fins, parts for the guidance and control systems, and more.
“You could potentially have these in the field,” said Jeremy Danforth, a Raytheon engineer who has printed working rocket motors. “Machines making machines. The user could [print on demand]. That’s the vision.”

The progress is part of a companywide push into additive manufacturing and 3-D printing, including projects meant to supplement traditional manufacturing processes. Engineers are exploring the use of 3-D printing to lay down conductive materials for electrical circuits, create housings for the company's revolutionary gallium nitride transmitters, and fabricate fins for guided artillery shells.
The process may reduce costs associated with traditional manufacturing, such as machining of parts. It allows for quick design and rapid changes because engineers only need change the digital model representing the part. As long as they stay within set parameters, they can have new parts in hours instead of weeks.
“You can design internal features that might be impossible to machine,” said Raytheon engineer Travis Mayberry, who is researching future uses of additive manufacturing and 3-D printing. “We’re trying new designs for thermal improvements and lightweight structures, things we couldn’t achieve with any other manufacturing method.”

Here is the photo of the missile model:

War is hell guys. We really don't need more weapons. We need more efficient ways to feed the world, not new ways to kill people ...

Did "Cult of Done" break MakerBot?

Bre Pettis is not only known for his work on Makerbot. In his early days he published a "Cult of Done Manifesto". It was very much considered the Maker movement philosophy praised by some important movement figures, community sites and regular hobbyists as their motivational motto. I even liked it very much.

But, while you can use it to develop a great DIY project can one use it as guiding philosophy for a large cooperation? Probably not. Obviously not.

When you look at the list of Makerbots problems including the last class action lawsuit about knowingly shipping machines with faulty extruders it makes you wander about how strong was Cult of Done ingrained into Makerbots corporate culture.

Here is the Cult of done manifesto:
  1. There are three states of being. Not knowing, action and completion.
  2. Accept that everything is a draft. It helps to get it done.
  3. There is no editing stage.
  4. Pretending you know what you're doing is almost the same as knowing what you are doing, so just accept that you know what you're doing even if you don't and do it.
  5. Banish procrastination. If you wait more than a week to get an idea done, abandon it.
  6. The point of being done is not to finish but to get other things done.
  7. Once you're done you can throw it away.
  8. Laugh at perfection. It's boring and keeps you from being done.
  9. People without dirty hands are wrong. Doing something makes you right.
  10. Failure counts as done. So do mistakes.
  11. Destruction is a variant of done.
  12. If you have an idea and publish it on the internet, that counts as a ghost of done.
  13. Done is the engine of more.

How big of a role has this philosophy played in creating problems for MakerBot? We will never know, but there is some strong suspicion.

Original post on Bre's blog:

http://www.brepettis.com/blog/2009/3/3/the-cult-of-done-manifesto.html

It took Bre 20 minutes to write it according to his claims.

MapleMaker Mini V2 3d printer with fully printable frame

MapleMaker Mini v2 is a 3d printer that has fully 3d printable frame and main components. It is an advanced open sourced DIY RepRap that can self-replicate to much higher percentage. Very interesting!
I wonder how sturdy and rigid it is?





Project description:
The mapleMaker Mini introduces you to the world of additive manufacturing and 3D printing. With your own 3D printer, your concepts and design ideas can be translated from computer drawings to physical objects in short period of time.
The aim of this kit was to reduce costs and create an accessible, hackable, upgradeable, and ultimately, user customizable 3D Printer. We believe that a 3D printer should evolve with it’s users needs and knowledge, and become a platform for any number of future upgrades and additions without the need for costly re-works or additional components.

MapleMaker Mini V2 tech specs:
  • large 8" x 6" x 6" build volume
  • All metal hot end (e3d Lite6)
  • Completely 3D Printed frame and all major components
  • Simplified frame construction
  • Simplified printed parts components, all printable in 36 hours or less
  • LCD control panel and electronics enclosures

You can find all the part on YouMagine:

New version of Slic3r is released! Version 1.2.9. Go and get it!


Slic3r 1.2.9 is now out, it is first new stable release in some 10 months with many new features and upgrades:

  • Customized Bed Shapes – Users are now able to implement custom bed shapes as well as rectangular and circular shapes using a very simple bed shape customization tool.
  • Incremental Real-time Slicing – No longer will slicing restart from the beginning every time you change a setting. In this latest version the new settings are only calculated for the remainder of the part, once implemented. When moving an object in plater, recalculations are also no longer necessary.
  • OctoPrint Integration – Easily configure, slice and upload data to the popular host software for 3D printers, OctoPrint.
  • Varied 3D Honeycomb Infill – Infill patterns are now able to be varied across the Z axis, rather than simply repeating the same pattern throughout every layer.
  • 3D Preview Updates – New OpenGL views have been added and the new 3D toolpath preview shows a very accurate depiction of the object to be printed.
  • X/Y Size Compensation – Dimensional errors can now quickly and easily be fixed within the Slic3r software (additional details on this feature can be found here)
  • Autospeed Experimental Feature – Keeps nozzle pressure and volumetric speed at a constant throughout a particular print project.
  • Rotate, Scale, Flip and Mirror – These options allow models to be manipulated prior to the slicing process within the Slic3r interface, making the software a graphical tool in itself.
  • Several bug fixes have also been included in this update including:
  • Parsing issues related to fixed regression
  • Issues regarding file names which use non-ASCII characters
