Re: Gekko print bed add on

Hi Guys,
I also found that 2mm polycarbonate bent quite a bit in the centre while printing becasue of the heat (or the model pulling it up).
Will be trying out some 3mm adn 5mm PC when I have a chance as, besides the PC beding, it stuck to it really well.
Cheers

Re: Leveling screws

We now, incidentally, use 4 screws on all 4 corners of our Up platofrms. Just makes fine adjustment a tad easier. I fully understand that, theroeticaly, 3 points is all that is needed but, for whatever reason, the 4 screws make it easier. :-)

Re: Rubber like print filament

Hi Lawrence, The principle is pretty much the same as on an injection molder, which melts pellets of plastic, driven by an auger, into a mold. But in this case, instead of shooting the plastic into a mold, it just extrudes it and lets the 3D printer do the rest. I don't intend on selling them, as it...

Re: Rubber like print filament

Watch this space... :-) I'm just in the process of machining the (hopefully) final iteration of our pellet based extruder for the Up whcih will allow you to print in any plastic at the same cost of injection molding, as it uses the same pellets. We are building it mainly to be able to print in therm...

Re: Up Enclosure

Flattery will get you everywhere! :-) Works out to about NZ$100 (hinges were $6 a pop, but I'm sure they could be found a lot cheaper) to make a laser cut enclosure. Will update final drawings on Thingiverse, as I've added a little rectangular hole on the bottom panel to make it easy to sweep out sc...

Re: Up Enclosure

Hi Lawrence, Had a go at reducing the depth of the enclosure to 300mm and cut one to test, but it's not a particulalry good option. If it is absolutely perfectly positioned on the printer, the platform can just clear at the front and back, but it does make life more difficult. It just makes the clea...

Re: Clearance for plastic hinges

If I remember correctly, the technical spec for the filament dimension is probably be 0.07" (from the Stratasys Dimension spec) which is 1.778mm.

Re: Clearance for plastic hinges

Yep. 2mm drill bit is pretty common. But, if I were you, I would try to avoid drilling if you can. It's just an extra step in the process... It's just a matter of experimenting a bit. I would start off with a 2.2mm hole (as EyUp said, FDM typically makes any internal hole dimensions smaller than des...

Re: Up Enclosure

Yep. All round generally better prints (which explains why the higher end printers all use heated enclosures). Stops any drafts affecting your print, and gives the printer a nice warm space to be printing in which helps with getting unstuck from paltform. Another indirect, but really important side-...

Re: Up Enclosure

Just had a quick look at the CAD and, in theory, should be doable to reduce the depth from 320 to 300. Just need to double check the clearance on the print platfrom from the back to the front position to make sure it doesn bump into the enclosure.
Will let you know tomorrow.

Re: Up Enclosure

Greetings all,
Just uploaded a newer version to Thingyverse, this one made entirely of 4.5mm acrylic, which should bring down the cost a bit, and is assembled with M3 screws instead of M4 screws. http://www.thingiverse.com/thing:34032

Hi All,
I've just assembled the first of my lasercut Up Enclosures, and it all went together like a dream... :D
If any of you want to build one, I've put the files on Thingyverse at http://www.thingiverse.com/thing:34032

Re: Chemical to turn plastic to more of a rubber state.

Hi Lawrence,
Plastidip works well for this. You can buy it at most good hardware stores. It's the same kind of rubber used to rubberize the handles of yur pliers, etc.
It's available in a can to dip, or in a spray can...

Re: Chemical to turn plastic to more of a rubber state.

Printing with pellets also reduces the printing costs enormously, as you are then printing with exactly the same form as for injection molding, so material is down at that price level... :-)

Hi Guys, We've just converted one of our Ups to print with thermoplastic rubber, but its still early days. We first tried with TPR filament but that cuased all sorts of problems because it was near impossible to grip a soft filament reliably while, at the same time, applying enough force to push it ...
