Big DIY Delta clay 3d printer made by Olivier Van Herpt

There are many big Deltas printing in clay. It looks like a natural fit to create ceramic and pottery with Delta type machines since they are round and tall. Here is a new project by Olivier Van Herpt. Main feature of this custom design is that Oliviers DIY extuder uses hard clay and not clay-water mixture. This approach enables bigger objects with higher details and sizes up to 80 cm x 42 cm.

Mcor paper 3d printed hammer taken by airport security

Mcor is well known for their unique paper based 3d printing technology. On of their sales staff was stopped by airport security and 3d printed paper hammer was taken as a potential "danger".

Here is what is reported on Mcors blog by that sales manager:

“Last night at the airport, security removed the hammer from my case. When I said it was made of paper he could not believe it, although he did comment that only the weight told him it was not real. He sent for his supervisor – same reaction. They then started to show everyone around and began to talk about making customized tools, parts for cars, phones, was this printer that produced the hammer model really made in Ireland, and many other comments.

In the end the hammer still had to be handed in as I could not take it in my hand luggage because, ‘it looked too real; it could be used to threaten people.’
Sorry I have lost the part. I’ll need another, but if it you could send by DHL it might be safer!”

Mcor’s first family, the MacCormacks, have had several similar experiences with Mcor 3D printed models at airports, but fortunately they had checked luggage and the option to go back and place the models in the checked luggage since airport security did not permit them to bring the models on the plane in their hand luggage.

Mcor used this "incident" and used is as a promotional piece to show how realistic their prints are. Which is completely legit. This story also peaks volumes about safety craziness of our current society ... sheesh, it's colored PAPER!!!

Now, how realistic is Mcors hammer? Take a look at video here:

Testing flammability of 3d printing materials

Here is a small improvised and non.scientific "test" of fire resistance (or flammability however you want to look at it) of various Shapeways 3d printing materials. The results are not surprising, basically gypsum burns worst. Don't try this at home folks. Plastics is flammable.

Tested materials were: Alumide (metallic plastic) UV Cured Acrylic Resin (Frosted Ultra Detail & Detail Plastic), Gypsum Full Color (full color sandstone) and Nylon (white, strong & flexible).

FLEKS3D flexible build platform system

FLEKS3D is a new flexible build platform cover that will enable you to upgrade your heated bed improve print adhesion and enable you to remove prints easily.

Key features as advertised on Kickstarter:

EASE OF REMOVAL OF 3D PRINT FROM BUILD-PLATE: The flexibility of the FLEKS3D™ Build-Plate makes it super easy to remove prints. We chose a highly resistant thermoset (plastic). This is because it is far more flexible and holds its form better than spring steel or other metals. We found that it is important to be able to flex the plate a lot for the really hard prints to remove. From our experience, just having a little bit of flex isn't enough for the prints that are really stuck on the build-plate
EASE OF REPETITIVE PRINTING BY HAVING SEVERAL EASILY REPLACED PLATES: The FLEKS3D™ kit comes with 2 plates. This makes it possible to interchange them for an uninterrupted 3D printing experience.
ULTRAGRIP WITH THE PROPRIETARY TEXTURE: The FLEKS3D™ Build-plate features proprietary texture that makes tape and hairspray unnecessary.
LESS DISRUPTIVE TO THE LEVELING OF BUILD-PLATE: Resetting the leveling of the build-plate after each print is tedious to say the least. This is not necessary with the easy removal set-up that the FLEX3D™ incorporates. This is because it comes with 2 easily removed plates that fit snug in the permanent frame.
BEST PRICE: Let's face it you work hard for your money. We don’t want to have you break the bank. We have made a great effort to be able to offer the FLEKS3D™ Build-Plate System at the best possible price. This is so we can offer this to as many people as possible.
HEATED BED: We have not done extensive testing with a heated bed. This is since our UltraGrip™ texture creates a very strong grip and a heated bed haven't been necessary to avoid warping. The FLEKS3D™ is made of a thermoform plastic with a melting point at 311 F or 155 °C. If a heated bed is used the temperature needs to be set bellow this.

You can get it for as low as 20 USD during their Kickstarter:

https://www.kickstarter.com/projects/fleks3d/fleks3dtm-build-plate-system

Company page: http://www.fleks3d.com/

FLEKS3d comes in 3 standard sizes to fit 95% of the printers. Small is 6" by 6", medium 8" by 8" and large is 10" by 10" inch. In metric units: Small 152mm by 153mm, Medium 204mm by 204mm and large 254mm by 254mm.
For MakerBot, there are custom FLEKS3D™ plates. These are available for Replicator 2, Replicator 2X and Replicator (5th gen)

FLEKS3D joins ranks with other print bed upgrades currently available like BuildTak or carbon surface from GermanRepRap.

How to use Filabot extruder to recycle your 3d prints and make new filament

Good people of Adafruit have made a tutorial on how to use Filabot filament extruder to recycle your 3d printed waste stuff. It looks like it is bast suited for organizations who gather a lot of recyclable models. It could save you some money.

They use electric garden chipper to grind the 3d printed waste into a mulch. The entire process could also be applied on any other DIY filament extruder like Filament Factory.

Everything is described in detail at: https://learn.adafruit.com/diy-3d-printing-filament/

Pre-sorting by color and material is key to maintain filament quality and color

Sintratec desktop laser sintering 3d printer coming soon at affordable price (Update: they presented a good machine and had great Indiegogo!)

Let the desktop laser sintering revolution begin!

Sintratec is company from Switzerland that wants to develop first desktop selective laser sintering DIY 3d printer. They aim to launch a crowdfunding campaign in October to raise money to ship at least 60 kit printers with price under 3999 euro ($5,277).

The main feature is that they will replace CO2 laser used in current SLS machines with diode laser which is cheaper and visible by human eye which gives more safety.

These videos show that they are already successful with prototype 3d printers and that the printed objects are strong:

Company homepage: http://sintratec.com/

Sintratec desktop SLS 3d printer prototype, the "Bobby" with 130mm cubed print volume

Example of object printed on Sintratec machine

Update (29.1.2015.):

Sintratec presented a finished machine and had a successful Indiegogo campaign where they raised $213,337 out of their $175,000 target.
Looks like we will have laser sintering on our desktops soon. Maybe they will be standard machine type.

Here is the presentation video:

Technical specifications from the Indiegogo:

Compact Size: 550x530x360mm. Fits on your desk.
Build Volume: 130x130x130mm. Laser sintering allows you to stack objects or place them diagonally in the build volume resulting in a maximum build dimension of 225mm and thus, making the build volume quite large.
Diode Laser: 2300mW, blue laser. The laser is compact and comes with high quality optics. The laser light is visible, making optical adjusting safer. Laser safety glasses are included in the kit.
Main Print Material: Nylon PA12 Powder. Very strong and high resolution parts. Flexible if printed thin. Dark in color to better absorb the laser.
Heated Laser Sintering: Both with a heating coil and optical heaters. A heated build chamber opens a whole new world of 3D printing: Objects don’t have to be fixed down on a build plate as it is the case with cold laser sintering, stereolithography or filament 3D printing.
Priced from USD 3999 to USD 4999 on Indiegogo

Final design looks much better then the prototype

DIY extruder for HDPE aquaponic plant growing strips

Extruders can be used for more than just filament extrusion. Here is a project from Web4Deb that makes growing media HDPE strips for plants in aquaponic or hydroponic systems from raw pellets. Auger based extruder is powered by windshield wiper motor and geared with bicycle gears. You could alos use it for HDPE recycling. Food from plastics ...

Extruder specs:

The barrel is heated with a length of Nichrome wire and and insulated with what appears to be polyimide tape.
The auger is a standard 3/4" wood auger bit (bought a set from Harbor Freight) and cut it down to length.
The auger is driven by a wind shield wiper motor which is geared down with a bicycle chain and sprocket.
The heating element draws around 16A at 12V (192W) from a computer power supply.
The temperature for the extruder barrel is controlled with a Teensy AVR micro-controller.
The die appears to be interchangeable.
The extruded HDPE is forced through a set of fan cooled rollers.
Two individual temperature sensors are located on the extrusion barrel.
The Teensy AVR micro-controller appears to be used to switch one or more relays through a transistor array.

RepRap Universal Plastic Pellet Extruder project

Here is a new extruder developed by Richard Horne that can print directly from pellets. It is much cheaper to print from pellets then to buy filament. One could also grind disposed or failed prints and recycle them directly.

There are several well developed projects for DIY filament extruders but their main purpose is to produce filament and not directly print from it.
There are also new machines like Sculptify David that print from pellets but nothing open sourced and adapted for variety of small home 3d printers.

This is project under development and Richard is asking for feeedback, so go and drop a comment on his video:

https://www.youtube.com/watch?v=nW4kmJAypZM

Excellent development! Kudos Richard!

Update:

Richard released his extruder and details about it can be found on his blog:

Tutorial on how to create molds for concrete objects with 3d printing

I'v been following HomeMadeModern for some time since they have some great DIY furniture projects with wood and concrete elements. Their design is very modern, minimalistic and easy to build.

In this project a better dish for dog food is built. It is curved and angled on one side so the dog can get all the food.
They use 3d printed full size prototype to create a mold and then poor the concrete mixture in.
The results look very good. You could use this technique to create any object in concrete, only limitiation would be the size of your printer.

If I catch some time in the future I'll try to build speaker housing made from concrete similar to P.A.C.O. open source project.

Great project! I like the idea of concrete furniture pieces, I don't have any experience with them, but even the concept seams better then those horrible IKEA pieces. And you can make them as unique as your own creativity.

Simple 3d printed pen and holder that uses ink inserts

Simple 3d printed pen with holder that uses some sort of standard ink inserts. Still it is an interesting design. It was made by Cain Adamson.

It is made on simple home 3d printer, but with more professional printer you can get fully functional mechanical pencil.

Plan B open source 3DP powder based 3d printer with detailed construction guide

Let the powder revolution begin!!!

Plan B is an open source 3DP printer and it prints with gypsum powder and a special binder. It is developed by Yvo de Haas (22 years old). 3DP printing requires no support material and prints at higher resolution than FDM printing. Printing in powder has the potential to be cheaper than most techniques, though more research into materials is needed and current objects printed on Plan B have a rougher surface. Models can be further strengthen with glue

Powder 3DP printing has some advantages and disadvantages when compared to FDM process:

Advantages over FDM printing:

Higher accuracy due to finer and more controllable nozzles. Even old and dated cartridges have a higher resolution (>96DPI, 0.26mm) than most FDM printers;
No support material is needed. All parts are always supported by the powder from the previous layers;
Excess material can be reused;
3DP has the potential to be faster than FDM. 3DP prints with more nozzles with simpler movements than FDM. Plan B isn’t yet though;
3DP offers a few unique materials and options for 3D printing.
It has the possibility print full color in gypsum and powdered sugar;
It can print in ceramic powder that makes models that can be fired in a kiln;
By binding in stainless steel powder a model can be created that can be infused with bronze in a kiln;
It should also be possible to bind graphite powder into a model that can be infused with epoxy, making graphite (carbon) parts;
3DP can print in almost any material that can be supplied as a powder.

Disadvantages:

Due to the powder, 3DP printing is messy;
Parts require post processing. Before processing, the parts are weak and brittle;
Powder printers need to be filled completely to work;
3DP can only print in one material at a time;
Hollow parts need escape holes to evacuate excess powder;
Thin walls and rods are weak and might break during cleaning.

Plan B technical specifications:

Build box dimensions: 150mm x 150mm x 100mm (l x w x h)
Layer thickness: 0.1mm to 0.25mm
Inkjet resolution: 96DPI (HP C6602)
Build material: Currently only Zcorp Gypsum and binder without color (this list will expand)
Step accuracy (X/Y): 0.05mm
Speed: 60mm/s (higher with future firmware)
Printing speed: Up to 30mm per hour (higher with future firmware)
Power consumption: Up to 160W (around 90W average)
Printer dimensions: 550mm x 350mm x 450mm (l x w x h)
Printer weight: 16kg
Frame material: Aluminum and 3D printed plastic
Linear guides: LM8UU on 8mm steel rods
Number of motors: 6 x NEMA 17 stepper motors
Other features: LCD screen, Keypad with rotary encoder, SD card reader
Price of materials 1000 - 1300 euro

Plan B currently prints only in Zcorp gypsum powder with no colors. Here are possible future materials that could be used in it:

3DP printing gypsum, a fancy mix of gypsum and different powders bound with a binder that contains mostly water and some unknown chemicals
Ceramic powders with Maltodextrine added, bound with rice wine or vodka [source];
USG hydroperm or other high quality dental plasters, bound with rice wine [source];
Sugar and some form of binder.

I'm still not fully clear on what is the binder used in this project, it looks like some mixture of water, glue (which one?) and alcohol (what type)?

Plan B hompage: http://ytec3d.com/plan-b/

Detailed instructions on how to build Plan B and operate its software:

http://www.instructables.com/id/Plan-B-an-open-source-3DP-powder-and-inkjet-3D-pri/?ALLSTEPS

Plan B powder DIY 3d printer

Plan B is improved machine when compared to Focus powder 3d printer made by the same creator or its previous iteration the "3DP Printer". Improvements over Focus are:

Dual feed hopper design and driven spreader increase the speed of the new layer process significantly;
The motors are removed from the moving parts, giving the gantry a higher speed and accuracy;
The aluminum frame is stiffer, thinner and makes the frame heatable (all fragile parts are thermally insulated from the frame);
Better piston guidance gives the Z-axis more accuracy and reliability;
The frame can be manufactured on a laser cutter or a flowjet

Plan B is work in progress, probable future improvements on it will be:

Different cartridges. The HP C6602 cartridges used on Plan B are not used because they are the best, the cheapest or the easiest to control. They are used because there is nothing else, it is the only Arduino controllable cartridge. At 96DPI and 12 nozzles, it is about the simplest a cartridge is going to be. There are plenty of other cartridges available, such as Piezo inkjet cartridges, which give great control over droplet size, The HP C51640, which has roughly the same type of control, only at 300DPI and around 100 nozzles, and CISS (continuous ink supply system) cartridges, which store the ink in an external tank, making it easier to replace the ink and refill it during printing.
The firmware lacks (among other things) acceleration. Motors are either on or off. The only place where the printer uses acceleration is when accelerating the X-axis for printing. Motors could easily move at double the speed when all axes had acceleration, while not really affecting the printing quality (inkjet doesn't lose resolution when printing at high speeds).
The software is a temporary solution right now. It works, but it is far from perfect. New software needs to be written that slices a file directly from an STL file (is under construction).
The printer should be isolated. The pistons heat up, but all of the walls are made of aluminium, acting as a giant heatsink. By insulating the printer, it will use a lot less energy heating the powder. It will also heat the powder more evenly, since it doesn't drain any of the heat at the walls.
Add a rough layer to the pistons. The pistons are based on FDM printbeds. This is wrong for 3DP. 3DP needs rough surfaces to grip the powder. At thin layers, the powder will actually break up when the spreader moves over.

Looks like 3DP powder machines are mature and here to stay. I welcome this new developments and healthy synergies with FDM. I hope this project will motivate other to develop new powder based 3d printers.

PS: you will have to disassemble, clean and refill with binder an inkjet cartridge (HP C6602). The details are the instructions. On a personal note: I HATE inkjet cartridges and the business model so it is a good use for this stupid product.

Here are some objects printed on Plan B:

AirEnergy3D DIY wind power generator you can print at home

AirEnergy3D is Polish company who wants to develop open source 3d printable wind power generator. If they are successful this will be great advancement for low cost wind power generation.

Key features:

AirEnergy3D is a 3d printed wind turbine that you can setup on your balcony, roof or take it camping
It can generate up to 300W of electrical power (this may be too optimistic, or the featured size will be increased, since the power for showcased size turbine is in 30W range in good wind)
It's small, it's durable, it's customizable and it' very cheap compared to existing wind based solutions
you can fit it in a backpack, move and assemble anywhere without using power tools

It is on Kickstarter now:
https://www.kickstarter.com/projects/43717383/airenergy-3d-a-3d-printed-opensource-mobile-wind-t

Company page:
http://omni3d.com/en/

Wind turbine that can be printed in modules. There are advantages and disadvantages to this design related to efficiency, but vertical axis turbine is easier to print than complex horizontal axis propeller. Read more at:
http://barnardonwind.com/2013/02/23/why-arent-vertical-axis-wind-turbines-more-popular/

Proof of concept makes a LED light up, but do keep in mind that gear systems reduce efficiency

There are similar projects even for the generator system, like this one:

http://diy3dprinting.blogspot.com/2013/05/small-3d-printed-wind-power-generator.html

... but I think there is a need for more integrated, well tested and optimized system. Open Sourcing it is a big plus and could make the technology spread and further developed by the community sand users.

If you want to build a home wind generator without 3d printing, here is an open source Zoetrope design build plan:

Repairing Ford Focus cargo cover attachment point and AC knob with 3d printed parts

Nicholas Durdan made a DIY 3d printed replacement hatchback cargo cover attachment point for his 2013 Ford Focus.
He measured the original part with calipers and printed it in PLA on a MakerBot Replicator 2.
The replacement is probably much cheaper and less time is needed then going to a retailer to get a new piece. Time saving alone is probably worth the effort.

If the part was released on the internet there would be no more need to buy this part anywhere in the word if you have an access to a 3d printer. Manufacturers should really think about making their parts models available to the public.

There are many examples of small home repairs done with same approach, like this replacement washing machine gasket:

http://diy3dprinting.blogspot.com/2013/11/daily-3d-printing-washing-machine.html

Like I said many times, if your business model depends on sale of small plastic parts, you should rethink it.

Update:

He also made a 3d printed replacement AC button:

3D4C multicolor 3d printer with CMYK filament mixing

3D4C is a new multicolor 3d printer which implements mixing of CMYK filaments to get desired colors in output object. This feature has never been implemented fully in mainstream FDM DIY 3d printer with many claiming they have achieved it successfully. We will see in the future if this one makes it.

Key features according to the developers:

The first truly 4 colors blending 3D printer.
Unique color blending hot-end extruder: provide accurate color blending.
Unique compact design, laser-cut cold-end extruders (4 units): ensure powerful and accurate filament delivery for 3D printing.
Original design Dual Building Platform with heat-bed: Platform 1 - MK3 Aluminium heat-bed. Platform 2 - 2mm laser-cut aluminium platform for large PLA printing (250 x 250 mm).
Special design electronics board: with 7 drivers to control 7 stepper motors.
Full metal parts: to provide accurate and fast printing, all parts are made of metals, probably the first of its kind. (except PTFE tube, couplings and belt)
Laser-cut Aluminium casing: to accommodate 7 stepper motors with a compact design, we use 2mm laser-cut brushed aluminium to ensure a stable framework for printing.
0.4mm & 0.8mm dia. nozzles: the first 3D printer provide 0.8mm nozzles to enable extreme speed printing. The 3D4C printer can do that because it has a solid framework and accurate filament delivery system. All 3D4C printers come with 2 nozzles for different applications.
Seamless original design
Thanks to the original design, the 3D4C is the cheapest color 3D printer ( even compare to 2 color printers ) available in the market.

3D4C technical specifications and comparison with Replicator 2X:

3D4C 3d printer is on Kickstarter now where you can get it for £850 ($1,445) as early supporter:

https://www.kickstarter.com/projects/3d4c/innovative-3d4c-full-colors-3d-printer

Someone asked me and here is the answer: CMYK stands for colors it uses cyan, magenta, yellow, and key (black).
