Be in 3d or not to be? As I myself have scanned and printed on a 3d-printer

«Since time immemorial, people have sought to reduce what are" Ehrlich Bachmann, "Silicon Valley", episode 7 i>

Now at the crossroads of technology 3d-scanning and 3d-printing service appeared (the dangers of началось all in Japan in 2012) for the production of 3d-figures.
In cinema 3d-printers flashed a series of "elementary" (ibid villain printed Liberator, but Habré printed painted in Photoshop Liberator earlier than in the movie) and "The Big Bang Theory" (whistle made many, but that's about the figures no one wrote).
After a post about what to develop various 3d-services in Russia , I want to share how the process of creating 3d figures from and before.
So, I went to visit the boys on the colored Boulevard and the subjugation of the 3rd measurement started.

Scan h4> Scanning takes about 10 minutes.
It usually occurs on the turntable, but it may be that the operator runs around you.
Scan looks like a bunch of flashes from the camera (see. The video at the end of the review)

Editing takes a maximum of an hour, if the user requests demanding "reduce belly" or "remove creases" in various places.
Editing program included in the scanner.

Remarkably, treatment of possible textures with space resolution:



Requires a lot of RAM.

Printer h4> My first impression, printer - a mixture gigantstkogo struynika, bread machine and vacuum cleaner.

The printer weighs 340 kg, and lives his life, sometimes it turns on and conducts self-cleaning.
The printer requires constant inclusion in the network.

Layer thickness - 89-102 microns
Print speed layer 2-4 minute

Consumables - plaster model of which is printed:



Printhead ("chump»):

A little video

Print h4> Program Management and preview


Preview in several projections.





Estimated time of printing and print a map of the current layer.

First, the base covered with a thin layer of gypsum powder. After that the print head is smeared with a special resin, glue gypsum in the right places, and usually black. Then apply the next layer of plaster, etc.

After printing, the excess plaster removed by special vacuum cleaner, and from hard to reach places with compressed air.

237 (out of 525) layer as print displays program:



237 layer in reality:



Once the printer is fully printed model - needs some time to dry.

It took 1, 5 hours, now we will "pull out of the oven»:



Remove excess plaster by "suction»:



Gypsum repurified \ filtered and goes to the cause.

Now remove the excess by "blowing»:









Bottom has 2 holes - one too blown plaster - a figure hollow inside

Cover me cyanoacrylate ("fixer»):



Half an hour to dry - and into the hall of fame:

Examples of work h4>

Capture memorable moments memorable form.







You can experiment with registration.



In my opinion, the most original figure.



Quality allows you to print even small patterns of clothing.



Conclusion
Still playing Quake2, I wanted to do with your face skin.
Is not far off the stage when, along with photo albums and will 3d-albums .
While that figure cause wow effect than you can use and make a cool gift.

P.S.
