  1. Ah! I found some old pictures! Here is the tail, aft fuselage and part of the aft wing with the solarfilm covering. Here's an exploded CAD view of the model from sketchup. Tandem wing. Flew well when I had it. CJ
  2. Wow thanks Neotko! My experience with 3D printing spans over 6 years now but the first half of that I had an UP! Plus and their software was very restrictive. Only two head temps, maybe 12 points of adjustment all in. So instead of changing settings I learned the machines flaws and designed around them. Having got my UM2 and later simplify 3D, the options are joyous and varied. But now I need to un-learn some of the techniques I use as instinct. Support is always something I try to design around. It usually comes off of an angle or compound curve with no resistance, but a flat has always been
  3. Hi all, I don't suppose there are any folk on here who use simplify 3D as their slicer are there? I'm exceptionally pleased with it on my UM2 but I do have a query when it comes to support material, largely in the difficulty of removing it post print. Done suppose anyone has support settings they are happy with and wouldn't mind sharing? CJ
  4. Hi Sander. Thanks for the comments. Oh yeah she'll fly alright. Side wind shouldn't be a massive issue as the finished weight is going to be reasonably high, makes for good penitration as us RC hobbiests call it. That and the motors are monstrous, 3.5kg of thrust @ WOT (wide open throttle) each. So I'll have 14Kg of lift to play with. I'm aiming for a total weight with lipo's of around 5kg. The speaker was going to go in a 1/12th scale Lancaster bomber model I have but it's been reassigned to this for engine noises, blasters etc... just before I start her up I've also got a sample of the han
  5. Hi all. Mine would go in the man shed if I could move in there. It desperately needs a clear out. It is a bit chilly in there as well. Convinced SWMBO to let me keep it in the study and came across an absolute gem of a find. Server cabinet, with keys, on wheels, with a working 230v thermostat controlled fan deck in the top. Outside a cleared out office at a site I was working at. Next to the skip. Barely a scratch on it. A little snug, and I need to wheel it out and open the back door to change the filament, but it keeps it at a nice 35deg.C with the cooling fans only coming on occasionall
  6. Thanks for the warm welcome guys. Feedback always welcome, positive feedback even more so . It does look a little inadequate when compared to that monster star destroyer I saw further down this section. But sketchup has its limitations. If my company go for this new printer I've also set aside a budget for solidworks as well as training for myself on the software to save time, and make them superior components. If I have the heart to I may redraw it on solidworks should they agree to pay the £9k bill. Chances are I might not bother though. I've got so many hours invested in this already. A l
  7. For an added sense of scale, here's the model in simplify 3D on my UM2 build plate. Initial print time estimates are 36 hours with support, 150 micron layer height and 55mm/s general print speed on the stock 0.4mm nozzle. CJ
  8. Hi all. Bit of a long intro as this is my first project post. Been hammering on the anvil of 3D printing for close to 6 years now. Got the company I work for interested in getting the UM3X based off the parts produced on my UM2 (to produce M&E components for a large UK supermarket chain). Spoke with a lovely chap by the name of Shaun Pulford whom works for Ultimaker GB while getting an invoice and after over an hour on the phone swapping techniques and whatnot he thought I would be interested in joining the community here. Having had a good poke around I've seen some very impressive prin
  9. Did you have a design in mind? I printed and flew a small lightweight model about 4 years ago, Printed in sections on my UP! Plus printer. For both the wings and fuselage I printed the ribs, leading and trailing edges, as well as the nose and tail of the plane. Linked the fuselage with CF Tubes (as suggested above). Then I covered it with solarfilm (a common RC plane wing skin material) which adhered to the ABS really well and shrinks when heated to form a tight skin over the wings and fuselage. Worked for me, printing the wings solid or hollow was too heavy for the size of model I had design
  10. Do bear in mind, most low end UPS' have a changeover time. I've measured this across a few units with an oscilloscope and have found that the nasty "modified sine wave" (square wave to you and me) doesn't properly kick in for 15ms in some cases. If you really have a concern about this, look up a "duel conversion" UPS. They are always outputting from their inverter (and most output a proper sine wave). So when there's a blackout or brownout, the supply is never lost. Then it's just a case of sizing one for your printer. CJ
