Some myths about PLA vs. ABS



.. but you probably know all of this ...

DIY 3d printer enclosure made from wood with hair dryer heating element


The enclosure developed by repkid is a simple wooden box made from thin MDF sheets and wooden beams structure. It is insulated by double-ply cardboard glued to the inside of the box. To prevent ABS warping it is heated by simple household hair dryer.


Parts printed inside the heated enclosure on the left, and ABS part printed without heated chamber on the right with warping.


The enclosure with printer inside it


Lasercut thermal vents. They can be done with simple hand tools also


Heater made from simple hair dryer


More advanced version of the enclosure with fumes extractor

Heated chambers for 3d printing are patented by some corporation and I'm not sure what implications patent law has on projects like this one ...

Low cost simple 3d printer enclosure made from plastic boxes




Cheap, simple and effective 3d printer enclosure made from two plastic boxes by rjacobsson.
He used Ikea boxes, but I think it will work with any plastic container and keep temperature of your print volume constant and elevated from surrounding.
It also reduces the noise and contains the fumes.
Like any enclosure without thermostat it overheat the motors but you should experiment until you discover what works best for you.

Nomad modular and scalable 3d printable DIY drone























Nomad is project in development of modular 3d printable aircraft measuring one meter in wingspan powered by electric motor. Future versions will be up to 50% larger and able to carry a GoPro camera in their nose. 

Nomad is a project by CaptainObvious   

From project description:
This is the Nomad, a new design I'm working on for a travel UAV/FPV airplane. This version has a wingspan of almost one meter, so it's relatively small. After I've completed and test flown I plan to make a 30/50% larger version to carry a GoPro camera in the nose for aerial photography.
The airplane is meant to be modular, the nose and tail sections are joined to the center section with nylon screws, the wings and stabilizers are detachable and even the wing panels can be kept separate to simplify repairs and testing new design ideas.
  • The wing sections are meant to be printed in a "Spiral Vase" mode, the internal spars and/or printing settings should be adjusted so that the printing head makes the spars by moving in from the bottom of the wing until touching the inner surface of the top of the wing, so there is only one seam at the bottom.
  • I have carefully modeled the fuselage parts so that most of them will print as a two perimeter shell using a 0.4mm nozzle, except where more thickness is needed.
  • The wings need two carbon fiber tubes, 8 and 3 mm diameter, the stabilizer also uses a 3mm carbon fiber tube spar.
  • The plane will use one brushless motor mounted on the tail with a 6" propeller.
  • Things left to do: flaperons, rib between the straight wing panels and the tapered external panel, optional nose wheel, camera turret and internal brackets and supports for servos and electronics.

Asiga Pico 3d printer with solid state UV LED light source




Asiga Pico is specialist 3d printer with size of a small kitchen countertop appliance. It is designed with jewelry, dental and medical industry in mind. It produces wax polymer casting for metal parts or uses medical grade biocompatible resin for things like hearing aids. It is priced at USD 6990. It comes with Asiga Composer software.

The Pico is the first 3D printer of its kind to use a solid state UV LED light source. The LED lifetime is up to 50,000 hours and is not classed as a consumable, unlike other systems. The result is consistent curing from layer to layer, day after day, year after year. UV light allows broader materials choices, such as water-clear and pure white materials.
The Pico now has an improved resolution of 39 micron pixel size with a build envelope of 40 x 30mm (X and Y), and a build height of 75mm (Z). With the ability to grow parts in 1 micron increments in Z, the Pico is ideal for high resolution applications such as dental, jewelry and hearing. When building at 50 micron layers, the Pico achieves a build speed of approximately 6mm p/hr.

T.Black DLP 3D printer by Trimaker made in Argentina

South America is also developing more 3d printers. Here is T.Black DLP printer by Trimaker from Argentina.




 

























Specifications:
  • Build volume: 180 x 235 x 180 mm
  • Positioning precision: 250 microns
  • Print speed: 20mm ~25mm / hour depending on the dye and the material.
  • Materials: rubber, rigid plastics and low viscosity plastic
  • Weight: 18kg
  • price: 38,720 Pesos ($4,936)

From company page:

PRINTING TECHNOLOGY
The printer is T.Black based stereolithography technology - the selective polymerization of the liquid resin with light. Unlike other inexpensive printers like MakerBot and RepRap, the Trimaker printer does not use a power head for depositing material during the printing process. Instead of using a head, the T.Black constructed by drawing the print object layer by layer with an optical projection - each layer of the object is actually a photo of each cross section. For each layer, the Trimaker projecting a light pattern on liquid resin solidifies and thus the parts constituting the object. The remaining resin can then be used as input for the next printing.
Advantage
More reliable technology.  T.Black technology is much more reliable because the control of complex mechanical movements is the part that usually fails. · High Resolution. Whether using light to build the object layer by layer allows a degree of much finer and more precise control. The resolution of your printer is more than 10 times higher than other inexpensive printers based on the technologies FDM (fused deposition modeling). The print resolution is one of the most important features that makes the difference between something with the quality of the prototype and the quality of the finished product and this is the main advantage of stereolithography technology. · Control of Color. use of liquid chemicals allows very flexible control of color printing. The user can change color very accurately by adding the proportion of dye which gives exactly the desired color. · Control of Multiple Properties. stereolithography process works with a variety of inputs. The designer can choose from a variety of materials with different degrees of hardness, density, transparency and other properties.

MADE IN ARGENTINA
The fact that both the hardware, software and materials develop in the country, are a great advantage for our clients when thinking about the after sales service, spare parts, supplies and personalized attention. Delivery times, technical support and input supply is greatly reduced on options imported printers today are available in our market. Finally, being a company Argentina, we will make all our releases, product testing, lectures and trainings, first in this market.
I'm not sure what technology tehy are describing in "control of color" part ... probably just a single tone of color in the resin ..

ASTERID 1100 3d printer by Plastic Scribbler


















From company page:
The Asterid 1100 takes our base model and adds a Smart controller LCD graphics display with SD card reader, it replaces the power resistor in the hot end with a heater cartridge and it adds a PCB heated bed. The Smart controller LCD display allows the user to control and print from the 3D printer without the need of a computer tethered to the printer (a computer is still needed to slice models into G-code). The heater cartridge heats up faster than the power resistor and in turn will regain heat lost more quickly. A heated bed helps reduce ABS warpage by keeping the model at or above the heat deflection temperature. A heated bed also assists in adhering the part to the build surface. In addition to the Smart controller, the heater cartridge and heated bed the Asterid 1100 also upgrades the print surface to borosilicate glass which provides a ultra flat build surface that has a very low thermal expansion coefficient. A flat print surface helps achieve world class results from a 3D printer due to the fact that the first layer is completely uniform. With three resolution settings (extra fine, fine and course) and a whopping 512 cubic inch build volume, our Asterid 1100 desktop 3D printer is the simplest, fastest and most cost effective tool available for making quality 3D models.

Sneakerbots shoes printed in highly flexible Filaflex by Recreus

They look good, but probably wont' survive much walking  ...



From project page:
The new sneakers by Recreus printed in Filaflex 1.75mm.
During months we have investigated and work hard to develop the 1.75 mm filaflex format. Sneakerbots are the actual proof that shows filaflex works becoming in the most elastic filament on the market.
The sneakerbots by Ignacio Garcia are inspired by 80s films such us back to the future, starwars, short circuit etc.
Should be noted that the new design is more comfortables than first one. You can vary the softness changing the percentage of infill. The tongue makes that laces don´t hurt foot.
Hope you print them, wear them and be the coolest maker in your city!!

3d printable cowling for enclosures with radiant heat source

Thingiverse user TimeFramed made a heater cowling for his enclosure. It is a sort of small fan driven air tunnel heat dissipation contraption :-) ... It improves heat distribution and makes it even trough the chamber.

 


























From project description by TimeFramed:
I've had real trouble with thin walls splitting apart, particularly on larger prints, (a. because they're larger, b. because the take longer to print -- i.e., overnight, and my printer is in an unheated shed).
Figuring the ambient temperature drop at night was the main cause, I decided to get an enclosure heater. And an inexpensive temperature controller. After installing and testing the heater, I found that using as just a radiant heat source was heating the enclosure surfaces near the element too much, so added a low-speed AC cooling fan (on the same relay, so it comes on with the heater. That solved the too-hot-in-one-spot issue, but tended to blow warm air onto one side of the print.
So, I made a cowling that funnels the warm air to the bottom of the enclosure, and to the front and back; to more evenly distribute the air.
The "stripes" you see on my 'top half' part are pieces from the first, horribly split, part glued onto the second print (that faired much better having been printed while using what survived from the first print).
The bottom half printed even better, while using the top half, and raising the extrusion temperature by 4 degrees.
Now I keep the ambient temperature of the enclosure at a toasty 38C.
