Chris Walby Posted July 27, 2018 Share Posted July 27, 2018 Hi Martin, I have been following with interest as one of our younger club members "printed and assembled" a ME109. Wings seemed very stiff and quite light. Issues with its fixed U/C and looked quite a stable flight until last time out. Discussion regarding its damage revolved around which bit to reprint and where to cut and shut, needless to say if it had been a far eastern more holes than wood model it would have been totally unrepairable. Just love the complex inner sections an tunnels. All the best and slow/steady with those CA fumes. Quote Link to comment Share on other sites More sharing options...
Martian Posted July 27, 2018 Author Share Posted July 27, 2018 Thank you Chris to be honest there is not much to say I'm hoping it will be of some help to anyone venturing down this new route and\ as Ian has said a lot of views but none the less thank you and by the way I read view every time you post Quote Link to comment Share on other sites More sharing options...
SR 71 Posted July 27, 2018 Share Posted July 27, 2018 But it is nice to get a little feed back, shows there is a interest, I prefer to see comments on my threads wether good,bad or of topic,shows there is life out there Quote Link to comment Share on other sites More sharing options...
Martian Posted July 27, 2018 Author Share Posted July 27, 2018 Hello Chris W , the fact that they are light may make impact less damaging but as you say cut and shut is possible as I have found out due to mistakes Quote Link to comment Share on other sites More sharing options...

Bob Cotsford Posted July 27, 2018 Share Posted July 27, 2018 and few of us have experience with printed models so there's not much constructive comment to add. Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted July 27, 2018 Share Posted July 27, 2018 We're watching and enjoying Martian. If it's any help my experience has been of breaking parts by dropping them on a tiled floor before assembly. They're a little bit brittle. But, once constructed, I've not had any problems at all. Here's another couple from aerofred, both fly really well. Quote Link to comment Share on other sites More sharing options...
Martian Posted July 28, 2018 Author Share Posted July 28, 2018 I,he found they are likely to break on the print line so soon fixed. Those two look great Chris i hope i manage to get a good finish like that. I'm going for the Red Bulls p38 polished Ali using rustoleum chrome spray over Halfords primer Quote Link to comment Share on other sites More sharing options...
Slickriff Posted July 28, 2018 Share Posted July 28, 2018 I'm another secretly watching with interest. IMHO this could be the future of model building as 3d printers get better and cheaper. It sort of has karma as well, as most of us started building airfix kits and could end up printing and building what are essentially giant airfix kits.

Martian Posted July 28, 2018 Author Share Posted July 28, 2018 Exactly what I said to my wife " look at this giant airfix plane" but you are right once you buy the files you can print as many as you want and these geniuses will create even more detailed and complex models in the future . Invest in a printer get to know it's setup and print a plane a week ,I still love balsa planes though .😎 Quote Link to comment Share on other sites More sharing options...
Chris Bott - Moderator Posted July 28, 2018 Share Posted July 28, 2018 Mine are both just the colour of the plastic its printed in, with some vinyl decals applied. I'll be very interested to see how you get on painting. Quote Link to comment Share on other sites More sharing options...
Martian Posted July 29, 2018 Author Share Posted July 29, 2018 Nearly painted but meanwhile some interesting facts about PLA polylactic acid not to be confused with people's liberation army any way it is biodegradable and boiactive made from renewable resources such as primarily corn starch ,cassava and sugarcane . It is soluble in chlorinated solvents ,melting temperature of 130_180c . A 3d printed plane will deform if left in hot sun or a closed car in the sun . Being biodegradable it will eventually breakdown but only in the right conditions . From what I have learned it is best not to use cheap PLA it s printing properties are unpredictable ,there is a market leader that sells reels of 1kg for about £30 .hope this info helps Quote Link to comment Share on other sites More sharing options...
Martian Posted July 30, 2018 Author Share Posted July 30, 2018 Hello all onto the last stage of the assembly which are the control surfaces These are the printed templates to bend the uc wire to I need to get some 3mm piano wire . Quote Link to comment Share on other sites More sharing options...
Martian Posted July 30, 2018 Author Share Posted July 30, 2018 I mentioned the mess up withe tailplane the next 2 pics show the start of the cut away process then when done the edges were cleaned up and reassembled the completed airframe with control surfaces fitted and primered then final coat which is chrome .although the print lines and joints are visible also were excess CA was not wiped of properly I'm reasonably pleased with it. The following close up give an idea of the surface defects from the print process I would imagine this would improve with refinements in the printing process. I can live with it these sort of defects are hard to see from several meters away. Halford primer adhesion was good Rustoleum chrome spray adhesion was good although the chrome surface comes of on your hands but that is not specific to 3d printed material I used the stuff on my Mustang and it was the same .when marking and logos are added I will give it a light coating of clear laquer. More later Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted July 30, 2018 Share Posted July 30, 2018 Posted by Andy Meade on 11/07/2018 09:05:53: Slightly off topic, but would your nephew have an STL file for that full bodied pilot that he'd be willing to share please Simon? They seem as rare as rocking horse teeth. The filelooks like the one that is is available for sale on CGTrader, the chap who designed them also does a USAAF, Luftwaffe and Imperial Japanese Navy pilot. The files aren't cheap - $25-39 a pop, plus VAT, but are nicely sculpted. Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted July 31, 2018 Share Posted July 31, 2018 You really seem to enjoy this 'new age' build, Martian. And maybe that's just the 'main thing' regarding building. Just take care of the US 'stars' position when finishing the deco for your birdie as you'll probably not be able to call in your friend Trump for a second time in a row...

Martian Posted July 31, 2018 Author Share Posted July 31, 2018 Ha ha Chris no chance of getting them wrong this time there will be none this is the Red Bull plane. the thing is with this new age build I,m willing to embrace something different but at the same time it is nowhere near the same as balsa but a more rewarding step from foam for me anyway Quote Link to comment Share on other sites More sharing options...
Martian Posted August 2, 2018 Author Share Posted August 2, 2018 Hello all well the airframe is completed and painted complete with Red Bull loge and red/white striped rudder. just have to fit all servos and retracts etc. Quote Link to comment Share on other sites More sharing options...
Slickriff Posted August 2, 2018 Share Posted August 2, 2018 Looks pretty impressive. It all looks to sit true, which would be a worry building from small blocks. I like it. Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted August 3, 2018 Share Posted August 3, 2018 ... I'm missing those US stars a little bit, Martian. It looks like you're going to put some mighty EDFs in there... Very nice work there on this 'special' bird. Cheers Chris Quote Link to comment Share on other sites More sharing options...

Thanks. it looks true up close so i hope its ok ..if the sections are printed accurately then all parts will fit I said earlier in the post that some sections are quite flimsy until glued and it is difficult to hold them is place while gluing so I glued small edges at a time a bit like stitch welding, patience is the key Quote Link to comment Share on other sites More sharing options...

Chris Bott - Moderator Posted August 3, 2018 Share Posted August 3, 2018 That look great Martian. I too was very surprised at just how true a fus or wing comes out after glueing many short sections together. The face ends of each part must be very true indeed. I guess they're guaranteed to be by the printing process. Quote Link to comment Share on other sites More sharing options...
Martian Posted August 3, 2018 Author Share Posted August 3, 2018 Next step has started by the acquisition of an Anet 8 so I can continue to experiment printing more planes i,m convinced it's possible to produce low cost repairable planes no real need to paint unless wanted . But I still want to build in balsa , the more these planes are designed and built the more the method will grow and improve Quote Link to comment Share on other sites More sharing options...
