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.

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:

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.

Pyra smart 3d printed oven or advanced heat chamber

Pyra is 3d printed smart oven. It can cook food but it can be used for any process that needs heat chamber. And yes, it is smart, Internet-of-Things device.It is open sourced also! Kudos!

Key features hardware:
  • Built on Fortus 900MC 3D Printer
  • Printed in ULTEM 1010
  • FDA-Approved up to 375˚ F
  • Raspberry Pi + Arduino
  • WiFi Compatibility
  • 12-Bit Digital Temperature Sensor
IoT capability:
  • Thermal Chamber Software
  • Smartphone Compatibility
  • HTML5 Web App
  • Cloud-Enabled
  • Built on Meteor
  • (Framework for Real-Time)
Other features:
  • Designed for Additive
  • Self-Supporting Structure
  • (No Support Material)
  • 80-hour Build Time
  • 3D Printed Heat Exchangers
  • Open Source
How it works:
A 3D printed fan in the base circulates air over heating elements and throughout specialized convective heating systems. The design eschews all the conventional wisdom of traditional manufacturing and embraces the capabilities of 3D printing.
This is evident through the design, from the profile of the complex heating channels to the shape of the smallest part in the heat exchangers 3D printed into the chamber walls. Even the overall shape of the Pyra was dictated by the constraints of FDM—sloping sides of 45 degrees are self-supporting and removing support material from the inside of the labyrinthine ductwork of the Pyra’s interior would be impossible.

Delta-T 3d printer has no rails, bearings, belts, pulleys or lead screws

Jeff Kerr who developed Lobo now has this cool Delta-T which has some crazy mechanical movements :-)

I'm not sure what are the advantages or specifications but I like the inverse looks of it :-) Print results also look solid. It should be very cheap since it uses fishing line, rubber bands and other low cost materials.

Nice work Jeff!

Delta-T in action:






Delta description:
This new 3D printer is a delta-type design but with a flying carriage suspended by 6 strings that wind up directly onto the motor shafts. No rails, bearings, belts, pulleys or lead screws.

This new version uses a Bowden-type extruder and a single spring-loaded tension post to keep the strings in tension. Still more work to do, but it's coming along.

Using hydrographics to color and texture 3d objects

Hydrographic printing could soon become mainstream way of coloring and texturing 3d printed objects. It could be as easy as printing a matrix on your standard inkjet printer and using it with water container and some additional chemicals. There are many DIY dip kits and hydrographics kits but non specially made for 3d printing. Software will have to be developed to connect various process parts.

Here are two projects and demonstrations in this area that look very mature and ready for implementation:

Texture Mapping Real-World Objects with Hydrographics by Interactive Geometry Lab


Project summary:
In the digital world, assigning arbitrary colors to an object is a simple operation thanks to texture mapping. However, in the real world, the same basic function of applying colors onto an object is far from trivial. One can specify colors during the fabrication process using a color 3D printer, but this does not apply to already existing objects. Paint and decals can be used during post-fabrication, but they are challenging to apply on complex shapes.
In this paper, we develop a method to enable texture mapping of physical objects, that is, we allow one to map an arbitrary color image onto a three-dimensional object. Our approach builds upon hydrographics, a technique to transfer pigments printed on a sheet of polymer onto curved surfaces.
We first describe a setup that makes the traditional water transfer printing process more accurate and consistent across prints. We then simulate the transfer process using a specialized parameterization to estimate the mapping between the planar color map and the object surface. We demonstrate that our approach enables the application of detailed color maps onto complex shapes such as 3D models of faces and anatomical casts.

3D cat model colored and textured with hydrographics



Computational Hydrographic Printing from SIGGRAPH 2015


Project summary:
Hydrographic printing is a well-known technique in industry for transferring color inks on a thin film to the surface of a manufactured 3D object. It enables high-quality coloring of object surfaces and works with a wide range of materials, but suffers from the inability to accurately register color texture to complex surface geometries. Thus, it is hardly usable by ordinary users with customized shapes and textures.
We present computational hydrographic printing, a new method that inherits the versatility of traditional hydrographic printing, while also enabling precise alignment of surface textures to possibly complex 3D surfaces. In particular, we propose the first computational model for simulating hydrographic printing pro- cess. This simulation enables us to compute a color image to feed into our hydrographic system for precise texture registration. We then build a physical hydrographic system upon off-the-shelf hardware, integrating virtual simulation, object calibration and controlled immersion. To overcome the difficulty of handling complex surfaces, we further extend our method to enable multiple immersions, each with a different object orientation, so the combined colors of individual immersions form a desired texture on the object surface. We validate the accuracy of our computational model through physical experiments, and demonstrate the efficacy and robustness of our system using a variety of objects with complex surface textures.

New Cura is out with powerful new features

New Cura is out with many new features!

Features list:

A new plug-in based system
The Uranium framework is a new plugin-based system that gives us great flexibility to extend Cura’s capabilities with ease.

Overhauled User Interface
The User Interface has been completely redesigned to create a far more intuitive, and pleasing experience.

Time-Quality Slider
We think users will love this feature. Instead of using 3 default profiles, we’ve chosen to implement a “time vs quality” slider in the new Cura. This creates more control over the balance between quality and printing time - especially for novice users or if you just want to quickly slice something.

Under the hood of settings
The Advanced mode is now configurable and enjoys many extra new settings, while being sure not overwhelm new users with too many of them. You can even create your own view settings, choosing which ones you want to see or not. Again, this makes it easy for new users but gives experts and tinkerers the ability to really experiment and gain even more control.

Support for high-DPI screens
The beautifully refreshed UI has been designed with high-DPI screens in mind, so on devices that have this feature, Cura looks amazing.

Optimized support structure
The powerful new CuraEngine features greatly improved support generation algorithms and additional options for support structure generation. This means both the positioning and degradability of support are improved.

Experimental feature: Wire Printing
We think users are going to enjoy this experimental new feature. We’ve implemented Wire Printing that will print objects as a structure of lines. To use it simply go to Advanced Mode -> Fixes -> Wire Printing.

An all important Undo/Redo feature
We listened to our community and it’s now possible to undo and redo most scene operations, like moving or rotating objects.

FUTURE FEATURES

To be included in future updates
  • The ‘Configuration Wizard’ and ‘Bed Leveling Wizard’ for the Ultimaker Original and Ultimaker Original+.
  • All At Once / One At A Time Printing.
  • A dual extrusion feature with a completely new workflow.
  • An improved way to incorporate ‘Lay Flat’, and ‘Split Object Into Parts’.
  • Future plug-ins will include support for DAE and AMF files. And for directly loading a GCode file. There will also be plug-ins to support PNG, JPG and other image formats. Support for loading Minecraft levels will also be implemented as a plug-in.
  • ‘X-Ray View’ will be added as a future plug-in.
Forever removed features:
  • Windows XP support has been dropped as Microsoft is no longer supporting XP, so they will no longer back port certain features that we require.
  • ‘Follow Mesh Surface’ has been removed from the engine, the same result can be achieved using no infill or top/bottom layers.
