Perfactory 3D printing test trial 2

So setting of the 3d printer we had two models 1 was a dodecahedron, the other was a spare, the dodecahedron was a model that contain another dodecahedron inside each other suspended in mid air. This was unknown at the time however. Adding both files to the magics software and creating a job to import into perfactory 3D we got the machine off running using pink material.

Here you can see about 10 millimetres of the model has been printed and is sticking out of the vat of resin. This is about an hour into the print the total print time is 4 hours.

image

This picture you can see the dodecahedron peeking out the bottom there is no dodecahedron that he done inside this is because the model was constructed without support material meaning of the internal parts will not supported . This means the currently the central internal model resting inside may be picked up later on during the print process later today. However although this part will be a failure the sphere is turning out nicely which should resulting in a clean sphere. We have to wait another 3 hours to see the final outcome.

3D printing at work DLP style

So, been working on setting up some 3D DLP printers at work which were used to print mouths for Pirates!, and discussing with suppliers of the machines abd another company, I have now located licences and software to run them.

Software is Perfactory RP 2.9 by EnvisionTec, suppliers of the Perfactory DDP printers.
Magics 13 by Materialise.

So after running and setting up the machines I got one connected and printing z test part.

I have not calibrated it, and I’m using out of date (by 1.5/2 years) so we will try and see what happens…

Animoko head,

So I have a new job! Well I have done for number of months, since November, and I’m loving it. I am Mechanical Engineer at Aardman Features Shaun the Sheep ltd. Working on the new Shaun the sheep movie.

Some tasks I have been working on include overhauling the MILO motion control robots, from a company called Mark Roberts Motion Control. Redesigning a focus motor using Nena 8 steppers, and generally designing, nodding and helping out Art department with metalwork requirements.

My current proje t is redesigning the heads for the Animoko motion control platforms, again from Mark Roberts.

This is required as currently it is awkward to fir the camera onto the head without having to use a secondary heavy motion control platform ‘rotate’.

This new bracket will allow the camera and sliding base plate to sit nicely direct, whilst keeping it all nodal.

Here are some pics of progress…

Base plate machines to size and slots added to allow for future use with other campers, note side bits fitted. Central holes to allow direct camera mounting shoudld that be required.

PLA 1.75mm and 3mm samples for the store – evaluation

I have recently been in contact with a company regarding supplying 3D printer filament at great prices.

These filaments are available in several lovely colours including Black, White, Blue, Bubblegum Pink, Gow in dark, Yellow, Green, Jasmine Green, etc etc…

And, i am to become a supplier of their filaments!
Well, with a friend, we are teaming up to supply this great quality filament.

I am currently running through some sample ammounts of filaments currently printing in 1.75 mm, but 3mm will be available firstly.

I am also in development of a multiple bowden cable extruder, which will enable multi colour prints and support material in PVA, again available through this company! which we are going to be supplying.

Watch this space for more news!

Quadcopter 3D printed gimble with brushless motors

Something i have seen over the past week is the 3D printed brushless gimble.

Those over at Hackaday and had 2 posts about this today and yesterday, aswell as discussion on Reprap forum, but it is a very interesting idea.

I own a quadcopter, although my flying times are small, i have had it in the air with my HTC desire S strapped to it to get some rather shakey camera footage.

 

Im thinking, i ahve accelerometers, spare brushless motors, spare brushless controllers and a quadcopter, not to mention FPV equipment! oh and 3d Printer…

Im thinking this is worth while to build one of these!

 

Should also make this… http://www.thingiverse.com/thing:76369

Gimbal controller

After further investigations i have found the controller is a board from Flyduino and costs $110, so i think i may have to wait for costs to decrease first!
