DIY 3d printed resin lens made on Form 1+


3d printing optical lenses is usually in domain of high tech companies, but Craig Broady developed and tested a method that enables you to print functional lenses on Form 1 + with clear resin. 

The process is well documented in a form of a guide on Formlabs forums and it involves a post-processing by polishing the surface with sand paper and scratch removal fluid.
The lens is 1.75mm at its thinnest and 4.32mm at its thickest, printed with a 50 micron layer thickness.


Working lens printed as a monocle on Formlabs 1+ with clear resin

Hopefully we will see more functional objects developed like small binoculars, telescopes and others ... Great job Craig!

Functionalize F-Electric conductive filament is one big step towards 3d printed electronics





Functionalize F-Electric conductive filament is new type of filament with much improved conductivity properties. It claims to be world' most conductive filament with “one thousand times more conductive than filament available today", and "enables anyone to print circuits, wires, sensors, power connectors, and other electrical components inside projects printed from popular PLA-capable 3D printers.”

With conductivity lower then the 1 ohm/cm which they demonstrate in measurements on video ,it looks like it is “the world’s most electrically conductive 3D printing (plastic) filament that enables electronic or electromechanical capabilities to be designed right into the structure of printed parts.” Conductive 3d printing filaments available on the market mostly measure in the 1,000 – 10,000 ohms/cm range.


Possessing that kind of electrical properties, it can be used to build all sorts of interesting objects like this 3d printed levitator device:

GMASS tungsten and bismuth filled high density ABS filament

GMASS is a new filament with high density ABS as main component with added tungsten or bismuth metal particles.
Only limited information is available without any tests or detailed review. There are almost no pictures of it.

GMASS is priced at 95 USD range for 0,5 kg spool.




From GMASS product page:
GMASS™ is a patent pending specially-formulated high-density ABS-based filament for 3D printing applications. It offers the ability to rapidly prototype high-density components. Using a variety of metallic fillers, it has a density approaching traditional metals, while offering the design flexibility of ABS plastic. Now your plastic parts can have the weight and feel of metal castings! Colored filament is available in limited configurations to allow further design enhancements.
The non-toxic fillers in GMASS™ make it an excellent choice for radiation shielding without the environmental impact of lead. While designed for rapid prototyping, GMASS™ also makes an excellent material for low-quantity additive manufacturing. 
Possible applications:
  • Consumer – Sporting goods, add weight, balancing
  • Healthcare – Medical x-ray shielding, nuclear medicine components, laboratory equipment
  • Industrial – X-ray shielding, reactor shielding, vibration dampening, inertial weighting

Specifications:
  • Filament diameter: 1.75 +/- 0.10 mm
  • Base material: ABS Plastic
  • Filler material: Proprietary compounds of bismuth and tungsten Density Range: 2.7 +/- 0.1 g/cc for bismuth, 4.0 +/- 0.2 g/cc for tungsten
  • Note that stated densities are for the filled filament material. Printed part densities may vary due to printer processing parameters, and should be confirmed by the user prior to use.

PROCESSING NOTES:
  • Recommended printing temperature: 230C
  • Recommended printing speed: 40 – 90 mm/s
  • We recommend using a heated bed: 100 – 110C
  • Advised nozzle size: 0.5 - 0.6 mm
  • Note: The filament will have a higher likelihood of clogging smaller nozzles such as 0.4mm and smaller because of the tungsten particles. Therefore a larger size nozzle is recommended.

RECOMMENDATIONS:
  • A heated bed should be used to prevent warping
  • The tungsten in the filament will wear down the brass nozzle after several hours of printing. Check nozzle before each print and replaced if worn.
  • To ensure proper adhesion to print bed, a small amount of ABS slurry can be applied to the bed before starting to print.
  • To achieve maximum density, you may need to increase the flow rate about 5 – 10%. We have also found that using a larger nozzle but using a 0.4mm size nozzle in the software settings will give you better density.
  • Note: Print at 100% in-fill to achieve full density on your printed parts.

Vagler V-8E education focused 3D printer

VAGLER International is a Swedish-Malaysian 3d printer company: They just released their 3d printer aimed at educational / school market: The Vagler V-8E.

http://www.vagler.com/

Technical specifications:
  • Max printing resolution: 50 microns (0.05mm)
  • Build volume: 13,500cm3 L, W, H 270 x 200 x 250 mm ( x x inches)
  • 1-Click printing;
  • Multiple printers and print queues from a single workstation;
  • “Child Proof” fully enclosed chassis means all moving parts for student safety and hardware longevity in a hardworking classroom environment;
  • “Teacher Lock” enabling staff to remotely lock the printer’s operation for student safety;
  • Magnetic door lock during printing, which prevents access to the 200°C+ heated parts;
  • Removable, non-heated printing plates, enabling quick access to completed objects.
  • Price: at USD 1,999 range























There are more and more 3d printers focused on very large education market and they mostly feature two main things: some sort of protection against children touching the heated parts and some sort of print job queuing. 
That tells me that we live in safety obsessed lawsuit culture (I had to buy and bring to school a set of carving technical knives at age of 10 as part of technical curricula) and that those features will not be sufficient if you want to sell in that market. We will see what will future bring in this field. Kids will have to learn 3d printing soon ...

How to run Easel CAD on Raspberry Pi and send g code to Arduino

Easel is a very easy browser based 3d design CAD software you can now run on a Raspberry Pi thanks to this tutorial by Sacha.

It is a small hack that could be used in specific situations, ie.: if you don't want to expose your more expensive design computer to workshop environment or maybe in educational setting where cheaper hardware is more affordable ...



Detailed tutorial can be found at:

http://thesimpleswitch.blogspot.com/2014/10/shapeokoarduinoraspberry-pieasel.html

Here is the workflow from the site:
Prerequisites: 
  • latest version of Raspian and Epiphany browser (type "sudo apt-get update" followed by "sudo apt-get dist-upgrade" in a terminal window if you don't have Epiphany installed)
  • Raspberry Pi Model B (hardware I tested on). Model B+, and compute module should work. I don't know if this will work on Model A, I suspect it will, but it will be even slower. Large/intricate designs might cause memory problems on the model A.
  • Some kind of Gcode sender 
  • I like GRBL Controller, it's more feature-filled and stable than Universal Gcode Sender 
  • Shapeoko attached to the Raspberry Pi via USB running GRBL on Arduino
On your design computer:
  • Create your design, save design as an Easel project.
  • You could do this on the Rasperry Pi, but using Easel on a Raspberry Pi is quite slow and does not display the 3D view.
  • On the Raspberry Pi:
  • Launch Epiphany
  • Load the file you created earlier - make sure the 2D view looks ok (you won't see a 3D view, Epiphany doesn't support it)
  • Go to machine>advanced>generate GCode. A progress bar will appear and CPU usage will max out for a while.
  • When the progress bar goes away, click Download GCode.
  • After a few moments (again, CPU usage will max out), a new unnamed tab will appear.
  • Go to that tab, you'll see a bunch of GCode on that tab. 
  • Click the gear icon in Epiphany, select "save as" and save the new tab as <file name>.nc 
  • Launch your gcode sender
  • Open the .nc file from your gcode sender and begin cutting normally.

ESA explores 3d printed Moon base concept

European Space Agency wants to 3d print a manned Lunar base.Similar to Sinterhab concept they want to use rover robots to 3d print with Moon surface material over inflated and pressurized surface.




From project description:
Could astronauts one day be printing rather than building a base on the Moon? In 2013 ESA, working with industrial partners, proved that 3D printing using lunar material was feasible in principle. Since then, work continues to investigate the technique. The shielding against radiation provided by a 3D-printed block of simulated lunar regolith was measured, providing important inputs for next-stage designs...
Soon the Agency is due to investigate another lunar 3D printing method, harnessing concentrated sunlight to melt regolith rather than using a binding liquid. 
But how might lunar 3D printing one day be used in practice? Foster+Partners, contributing architectural concepts for the original study, put together this outline of a hypothetical mission to 3D-print an entire a lunar base, illustrating the design factors that steered them in their work.
The rim of Shackleton Crater at the lunar south pole was chosen for the base location. The Moon’s rotation is such that the Sun only grazes its poles at low angles. The result is a near-constant ‘peak of eternal light’ along the rim of Shackleton Crater, beside regions of permanent shadow. Building in the vicinity of such a site would offer plentiful solar power, and relief from the extremes of heat and cold found across the rest of the Moon. 
In reality any lunar base remains firmly on the drawing board, but each small step forward in research makes future lunar colonisation a little more feasible. In November 2014 more than 350 experts came together for a two-day Additive Manufacturing for Space Applications workshop at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. They discussed the potential of 3D printing – also known as Additive Manufacturing – to transform the way the space industry operates and begin preparing common standards for its use.

LumiPocket simple and compact SLA DLP 3d printer

Here is an interesting DLP SLA 3d printer design that can be used with almost any DLP projector. It is a cylindrical resin container with z motion add-on that enables you to use it as resin vat under a projector.





LumiPocket technical specifications:
  • Technology Stereolithography (DLP)
  • Printer Dimensions: 8 x 8 x 28 cm
  • Build Volume: 100 x 100 x 100 mm
  • Layer curing time: 3000ms-8000ms

  • Resolution X, Y axis: 50/100 microns (depending on the projector used)
  • Resolution Z: 50/100 microns
  • Electronics: Arduino Micro
  • Resins tested: SpotGP, FunToDo
  • LumiKit Includes: Finishing tray, a set of tweezers, 2 scrapers, protective gloves and glasses.
Supported projectors: 
  • Almost every DLP projector can be used. We do not recommend any modification to your projector (unless you really know what you are doing and want to void its warranty): instead, we provide you with a list of compatible projectors we already tested. Should you want to buy another model, we also provide a set of technical specifications that meets our requirements.
  • For jewelry and castable resin for metals a FullHD projector will provide the best results.
  • Minimum Requirements 2000 lumen, 1024x768
  • Recommended 
  • 2500+ lumen, 1280x720 or above
  • Tested Optoma dx325, Acer x1260, Acer x1240, Acer 6510bd, Acer P1283, Acer P1500
Key features (from Indiegogo campaign):
  • versatile: Just by adjusting the projector height, you can go from printing very detailed object, like jewelry molds, from bigger parts up to 10cm diameter by 10 cm tall. This means that LumiPocket can be used to print many different objects, not just tiny parts!
  • fast:With the best projector we tested (AcerP1500) and our recommended resin (FuntToDo IB) the curing time per layer can be as low as 0,7 seconds, with a printing area of 10x5cm. With a ~320$ projector like the Optoma DX325 or the Acer x1240/60, curing time per layer is about 3-7 seconds, that is still faster than even more expensive FDM printers, and remember that with DLP projection, printing speed is not affected by object complexity, or by the number of parts to be printed on the same tray.
  • reliable: and requires little maintenance(Goodbye, disposable vats and expensive non-stick coating) With our top projection system, we removed one the most annoying parts related with light curing resin: the need to replace often the printing vat, a delicate transparent contianer for the resin, that does also need expensive anti-sticiing coatings, often difficult to apply that last only for a certain number of prints before start degrading.Projecting from above, we removed the need for a special vat, and it will double its function of printing vat and resin container with its cover for storing the resin. You can have one for each type of resin you have and changing material on your printer is as simple as swapping the vats.
  • really easy to use: We designed a cross plaftorm software that takes care of everything: you just need to load a .STL file and it will take care of the slicing and printing. If you don't have 3d modeling knowledge, you can use our integrated 3d search engine that will let you browse online for 3d models , our use our basic templates to print many customizable objects, from Litophanes to personalized rings or keychains. It supports the newest input technologies like the Leap Motion, an innovative devide able to track your gestures and hands movements, providing a new way to explore and model 3d objects.

LumiPocket is on Indiegogo now:

Fully 3d printable universal filament spool holder




Very useful universal spool stand which is fully 3d printable developed by Creative Tools. Cool! Will print and use it :-)

From spool stand description:

A fully 3D-printable rotating stand for filament spools, designed to be easily made without the need for fasteners such as screws, nuts, shafts, glue, etc. Every single component in this spool holder comes right from your 3D printer's filament.
The spool holder's spindle is shaped to fit the vast majority of commonly used filament spools with shaft holes ranging from 16 mm to 62 mm in diameter. It is also compatible with spool-less filament coils.
The spindle which holds the spool's weight rotates on its own roller wheels, which makes it turn effortlessly.

The spool holder included an arm for filament guide tubes of both common sizes 1.75 mm and 3.0 mm. The arm also contains a pocket for inserting a piece of sponge which acts a a filament filter - thus keeping the filament clean and lubricated. 
Features:
  • Easy to 3D print
  • Needs no glue or fasteners
  • All parts can be 3D-printed
  • Fits almost any filament spool size
  • Has built-in filament filter!
  • Can also hold spool-less filament coils

Maker Club will teach your children robotics with 3d printable robots





... and beside children they will also teach me. I just found out about Maker Club, and I really like the idea behind it. They provide very detailed guides and all the resources to learn robotics. They devlop electronics and mobile apps to control their projects.

From Maker Club page:

Born in Brighton, UK, Maker Club has single mission - to make learning fun. We’re based in the cities most dynamic workspace, The Fusebox, a collection of start-ups, dreamers and thought leaders that try and make the world a slightly better place.
Our vision is to make learning about electronics and coding fun, accessible and relevant to young peoples lives. When you add micro controllers, servos and sensors to 3D printing, the possibilities are limitless and we want to harness that power to inspire the next generation of inventors.
We’re developing an ecosystem where people can learn, build, collaborate and even sell their robotic creations with the aid of a learning platform, marketplace and an intuitive mobile application - but, this is just the beginning. We’d love to hear from you, so why not get in touch with us today.

As far as I see most of their stuff is under CC license that is great for me as Open Source supporter.

Here is their homepage where you can get full building instructions, code and STL files for their robots:

LEGOMakerBot3D uses Lego bricks to 3d print objects

LEGOMakerBot 3D is 3d printer developed by Will Gorman. It doesn't use filament but uses 2x2 Lego blocks instead to compose 3d objects.





Here is LEGOMakerBot 3D in action:



The machine is made from LEGO MINDSTORMS EV3 (31313) with additional bricks, nine motors and sensors.

You can find more details and building instructions at:

Weld3D is developing arc welder DIY metal 3d printers

Here is a new DIY metal 3d printer based on welding process from Weld3D. It is still under development and it is combination of CNC and arc welder.




Weld3D is new company based in Huntsville, Alabama. We will probably hear more from them in the future.

Weld3D homepage:

http://www.weld3d.com/

Weld3D metal objects are still rough, one on the far left was probably post-processed




Do keep in mind that there are several welder based machines under development, to see more look at the tags beneath the post and click to follow.

3D Fabrication Desk is ideal workstation for your 3d printer

Peter Borges deigned 3D Fabrication Desk workstation that can be cnc laser cut from plywood as a part of renovation at Prince Lab. Hopefully some day the deigns will be fully available and open sourced. Now there are just some low-res image templates at project page.

From project description:
A workstation created in response to the need for dynamic design spaces as part of Prince Lab transitions into a more maker friendly facility.
Brown University School of Engineering recently embarked on a partial renovation of Prince Lab to facilitate a more interdisciplinary and creative approach to solve design problems. The space is largely based off of the recent proliferation of maker spaces across the globe.
I really like the design and material, great work Peter!

DIY manual digital fabrication or what to do when you don't have access to CNC

You want to design something and cut it on a CNC but you don't have a CNC? No problem!

Here is a tutorial by Jonathan Odom on how to design something in CAD, make paper cutting template and then cut it by hand. It's a sort of manual digital fabrication. You can call it contradiction-in-terms, but hey, if it's stupid and works, then it is not stupid.

Since I don't have a CNC or access to it (but I will get one some day) I find this useful since I could create some simpler smaller projects.

Jonathan designed and made a wooden stand for a laptop using simple tools and materials:
  • Jigsaw
  • Hand Drill + Bits
  • Wood Files (rounded and flat edged)
  • Sanding Block
  • Rigid straight edge used a level.
  • Pressure Clamps
  • 3/4" Plywood (18" X 24" panel)
  • Printed paper template
  • Spray Adhesive

Be your own manual human powered CNC cutter!
