My turn to share my projects ! 
If you’re new to aeromodelling, think “small airplanes you design, build, and fly from the ground” 
. My corner of it is RC gliders. They often have no motor; you launch them by hand, then they surf rising air from slopes and warm thermals like birds on an elevator 
. It looks simple, but making a light, stiff, precise airframe is the real challenge. Wood and foam can get you there, but it’s a marathon of cutting and sanding until your bench looks like it snowed indoors 
. Carbon-molded gliders fly brilliantly, yet the price climbs while your wallet… does not 
. I am French, how you say, ze goal is to fly more and sand less 
.
Here is my plan. I would print a two-meter span sailplane on the K2 Pro Combo, using recognized airfoils and lightweight foaming filaments: LW-PLA, LW-ASA, and HT-LW-PLA 
. These materials expand as you tune temperature and flow, trading solid plastic for micro-bubbles 
. Think of it like a really good baguette: light inside, crisp outside, and it still holds its shape when you slice it. That means low mass with skins that feel surprisingly stiff, exactly what a glider loves .
The printer suits the job. I need to print wing modules with roughly 30 cm chord, and that fits the platform so the airfoil stays honest and the number of joints stays low 
. A warm, stable chamber keeps foaming predictable, which helps with LW-ASA and especially HT-LW-PLA . The extrusion path handles abrasive formulations, and I will pair it with the hardened nozzle to keep edges sharp 
. With CFS I can run multi-material jobs so skins and inserts share the print without drama 
.
I already flew a first prototype. It launched, circled, and behaved… right up to the moment I parked it in a tree 
. The airframe passed the test; the pilot will get a firmware update 
.
I am now modeling the V2 in 3DExperience, aiming for about 500 g all-up at 2 m span by dialing gyroid infill and local wall thickness 
. For the span and cost, that target sits in a very happy place if I compare it to what I can find in the market 
. First wing already printed (just have to sand the glue now)
I want this to be reproducible. I will print small foaming coupons to map expansion versus temperature and speed, then lock flow settings that preserve dimensions for each filament 
. The wing will be modular with printed shear webs and spar sleeves, snug joiners, and clean leading and trailing edges so the profile stays true 
. LW-PLA will cover most skins, LW-ASA will guard the surface contact between each part, and HT-LW-PLA will reinforce hot spots like the nose or motor mount 
. I will use simple jigs for incidence and washout, keep weight logs and CG checks, and run quick torsion tests so others can copy the recipe 
.
Flight testing starts with gentle hand launches, then slope and thermal sessions 
. I will log sink rate, wing loading, and glide impressions, and I will share what actually works in the air, not only what looks pretty on the bench 
.
Once V2 is printed, flown, and refined, I will release everything for free: .3mf files, STLs, slicer profiles, a compact build guide with flow curves, temperature ranges. Then I will scale the method to a four-meter RC sailplane. Same idea, bigger smile 
. And that’s why it’s funny. Mechanically speaking..It will be easier to print as the airfol is way bigger (just will take longer to print though) !
From gyroid to glide, let us trade cost for know-how and turn sanding marathons into repeatable prints. Bon vol 
.
And just to notice any late participants, the event ends in 6 hours, 28 minutes, 12 seconds so share your projects 
! The more, the better
Never got scared at night ? Lol
Lets just say I almost had to move K2 out of the dinning room…. Wife and kids got use to them over time. I also now have a battle droid printed on the three older CR-10s.
Project: Double Ritter Sport Box
I already have the K2 Plus. If I’m chosen as the K2 Pro Combo pioneer on the forum though, I will use both together to build a very serious solution to a very serious problem: The forum admin keeps ending up with a single Ritter Sport in a 3D printed box when I visit events and give it to his colleagues to bring for him as a gift. My project is to print a box that safely carries two bars and actually deliver two.
K2 Pro prints the PA-CF outer shell for stiffness and drop resistance while the K2 Plus prints the lid and inner insert at the same time.
I can swap the CFS between them. If I want multicolor labels or icons on the lid I move the K2 Pro CFS to the K2 Plus for up to eight colors. If I need to iterate two designs that hold the chocolate best, I split four and four and test both at once.
If I win and then deliver a double chocolate box, some people might take it as proof that Optimus is bribable. That is obviously false. It simply proves he can be influenced by high quality snacks stored in well engineered containers. This is a serious project with a practical, real life application. Completely different.
I want to print swords for cosplay which have electronics built into the printing process instead of printing in halves, placing the electronics, and gluing the parts together. I think this new printer with the large base can do that for me. Thank you for reading.
From conception to construction ? So you will use a code in python or something like that (Fortran maybe ?) instead of the classic slicer ?

Thank you so much !
I’ve been jumping around so much like an idiot, I think I broke one of my toes, but it was worth it. ! Lol
