Vacuum Forming Rig
stechi

 I wanted to produce a vacuum forming machine that would allow me to do small parts, just for experimenting. I wanted to go for a self-contained unit with its own heater and vacuum pump. I know you can do a lot with an oven and vacuum cleaner, but my challenge was to do something neater than that, a self-contained machine.
I won’t go into how vac forming works, because there are plenty of explanations on the internet. But the main concerns are to hold the plastic sheet, to heat it, to hold it on an airtight moulding table (platen) and to reduce the air pressure to make the moulding. In short, the heater softens the plastic sheet that is held in the frame. Then the frame is lowered onto the platen, where the object is. The vacuum pump underneath then draws out the air under the sheet so that the plastic forms the shape of the object; it cools and the job is done.

Visual 3D Print Finishing Guide

Tom Nardi

With 3D printers now dropping to record low prices, more and more people are getting on the additive manufacturing bandwagon. As a long time believer in consumer-level desktop 3D printing, this is a very exciting time for me; the creativity coming out of places like Thingiverse or the 3D printing communities on Reddit is absolutely incredible. But the realist in me knows that despite what slick promotional material from the manufacturers may lead you to believe, these aren’t Star Trek-level replicators. What comes out of these machines is often riddled with imperfections (from small to soul crushing), and can require considerable cleanup work before they start to look like finished pieces.

Imprimir em 3D leva muito tempo... 

E se vos encomendam uma Dúzia de Objectos iguais?

Ora aqui está como fazerem duma peça, muitas, pelo método da Moldagem com Resina.

Eles até oferecem Kits, para o caso de quererem tudo pronto:

Mold Making & Casting Tutorial: 73-20 Figurine Mold

This
 is a basic "cut block mold" that may be used to reproduce figurines,
model parts, or small ornamental pieces. We used PlatSil 73-20 to create
 a fast, accurate mold. 73-20 is an easy to use 1:1 ratio silicone that
may be demolded in ~1hr. Upon demold, we cast an EZ Flo 60 positive.

Robotic and Automation Applications
There's No End To The Wonders Made Possible By SDP/SI.



Whether it's diffusing a bomb or performing a delicate surgery, every robotics application is dependent on one thing: precise motion.

SDP/SI proudly includes the robotics industry among the many markets it supplies with quality miniature drive components. Robotics is especially important because the possibilities for applications are nearly endless; as a result, robots have become far more commonplace in many different industries over the years. No matter what the application is, the success of any robotic operation hinges on one thing: precise motion. The precision mechanical components offered by SDP/SI ensure just that, whether it's a custom gear assembly, a standard stock item or a modified standard component.

3D Printer Job Cost Calculator



We created this little calculator for our friends who run 3D printer farms in their garage as a side business. It’s a quick way to give your customer a quote on a job. The “cost per hour” field lets you easily play with what you want to charge for printing time.

As a fun thing to do, try inputting different costs for “cheap” filament vs. “expensive” filament. Then, try adding 30 mins to the “job time” to simulate having to unclog a jammed extruder / hot-end for using cheap filament and check out the difference in final cost. This is why we put more time and energy into quality over cost.

Canhão Magnético de repetição! A Repetition Gauss Cannon! YEAH!

A Repetition Gauss Cannon! YEAH! 
3D print it from the Net:

 

Repeat fire Gauss Cannon!

It's a Gauss Gun, (10 mm  cube Neodymium magnet),  with the Magnet below, off the way of the spheres, a Newton Cradle inside, and a Ratchet!
Simple. But SOMEONE had to think of it! ;-)
And as the Ratchet keeps the roller balls, (9.5 mm diameter, for ball bearings), in place, you can re-load it for ever. The wheels are kept in place by slightly heating the axis, then, pressing.
