LW PLA Stress Test | Reinforcing and Painting 3D Printed Parts | RC Harrier

[@maxun1]

What I love is the pain shaker LOL fantastic idea.

[@ThreenaddiesRexMegistus]

Excellent methodology! I am envious of your superbly organised workshop.

[@GRDwashere]

The other lesson I took from this video is that I need a grinding room, a printing room, a composites room, assembly room.....

[@renerosentraeger]

😅👍

[@nevillecreativitymentor]

Standing on YOUR shoulders .. I see further !! THANK YOU. ❤❤❤❤❤❤ I am building a 3D printed Winglet and this knowledge is priceless. Whenever I am done I will share my expereinces.

[@PaulinKantue]

Really good video! This is why we use youtube for experimental learning. I will definitely try reinforcing my LW-PLA with glass resin for additional strength and to compensate for the available porous structure.

[@renerosentraeger]

Go for it mate 🙌

[@edfhobbies556]

WOW !! Just looked at the stress test and 3 - 4 lbs on the outer edge of the part is EXXCENT !! I'm really impressed with LWPLA !!! This video is very informative !!!

[@renerosentraeger]

Thanks mate 😁🙌

[@edfhobbies556]

@@renerosentraeger have you attempted fiberglassing the outer skins of lightweight PLA for strength test. I want to build larger models with lightweight PLA and would love to know if fiberglassing the outer skin would make a considerable difference versus just resin and filler

Super Video René. Hätte nicht gedacht, dass es durch das Bestreichen mit Harz einen signifikanten Festigkeitszuwachs gibt

[@renerosentraeger]

Und das bei minimaler Gewichtszunahme 😊👍

[@marcp.5679]

hab das jetzt nicht ganz rausgehört... ist das normales Laminierharz oder ist das ein Spezial resin zum Drucken 😅

[@paoloraddri]

Thank you René for all the useful knowledge you are sharing. I've just finalized my F35 and I'll test without resin but on next frame I'll consider for sure the epoxy coating.

[@renerosentraeger]

You're welcome Paolo. Are there any pics of your F35?

Hallo Rene, tolle Arbeit. Ich habe neulich für mich sehr ähnliche Versuche gemacht, nachdem ich nicht viel über die "Veredelung" von LW PLA gefunden habe. Ich habe gleich mit 49g matte gestartet. Allerdings zunächst aus Jux mit DLP UV Harz. Das funktionierte jedoch sehr gut. Und es lässt sich punktuell und auf Kommando aushärten. Man muss es nicht anmischen und bei künstlichem Licht hat man eine praktisch unbegrenzte Verarbeitungszeit. Anscheinend habe ich mit Mikroballons abgespachtelt und mit 1000er nass geschliffen. Die Lackierung steht noch aus aber die Oberfläche sieht bereits sehr gut aus. Ich finde gut das die deine Modelle auch ohne Panellines anbietest. Das macht das aufziehen der Matte schließlich wesentlich leichter;-) Danke für deinen Beitrag!

[@renerosentraeger]

Ja gerne.

[@nocknock4832]

great video! liked the whiteboard part

[@renerosentraeger]

😉👌

[@RC-Jetprint]

Nice video Rene….perfect analysis and tips ….keep on this passion 👍

[@esmaeel.kargar]

16:50 Preheath the sanded part before doing resin coating and use lower-temperature resin. this method helps the resin to get sucked into the LWPLA foam matrix.

[@maxun1]

Actually will be nice to have a room with temperature control and do the job inside. LOL

[@evel-knievel]

Hi René, Nice video as usual, good work on the lw-pla resin combo research! I have been thinking about similar technique using SLA resin to coat parts and curing with UV. Thx for the tip, will be trying that out myself soon ;-) Cheers

If you could add a resin and glass covered part in the comparison, that would make it even more interesting. I'd really like to know how it compares in terms of weight and strength. Some really nice work you're doing nonetheless!

[@renerosentraeger]

Is in preparation 😁👍

[@robtomben]

I glassed one of my printed flying wings. It added a lot of strength and rigidity. It also added heat and puncture resistance without adding very much weight.

[@Athiril]

@@renerosentraeger did you end up making this test?

[@Athiril]

@@robtomben what was the before and after weight? What gsm glassfiber did you use? 1 layer with resin brushed on?

[@maxun1]

I'm a composite airline mechanic and yes will add some weight but will be super strong.

Yes here kzbin.info/www/bejne/a4Spknydqcqkrdk

[@rafiotlecomte]

Nice process what do you think of lw asa ? Maybe nylon with carbon will not need resin on it ?

Asa is more temperature resistant but less stable. So no fortune.

can you suggest a 3d printer if i wanted to start printing large planes? i was looking at the bamboo labs but it seems really small for the sized planes i would like to build. thanks

[@renerosentraeger]

Bambu x1c is the best. And has the optimal size. Qidi x max 3 is also very good and bigger.

[@vmaksym]

Is there any surface deformation on direct sunlight?

[@jpbevin]

Hi Rene, awesome video with great information. I'm currently considering how to prepare and paint a fully 3d printer lw-pla aerobatic plane. Which handheld grinder are you using for your surfaces?

I am trying to print a wing of 500mm in Lw pla. Do you recommend printing the wing all at once. Or would the be more at stability by glue the parts together? ( have mod z axis to my 3d printer)

Depend on the stiffness of the wing and precision of your printer👍

Moin, durch dein Video bin ich auf den Aktivator für Sekundenkleber gestossen, was ich bis dahin nicht kannte. Kannst du mir mitteilen, welchen Kleber und Aktivator du erfolgreich verwendest? Irgendwie finde ich den aktivator nur zum sprühen und nicht zum pinseln.

[@tungym]

Will water based polyurethane has some rigidity advantage? Less messy to apply.

[@renerosentraeger]

Think it is not strength enough.

[@olisandy0]

Why not lw-pla + surface light carbon fiber ?

[@renerosentraeger]

Makes it too complicated and too heavy.

[@zozolione]

Hallo René, ich versuche mir meinen Traum Jet zu basteln 120mm EDF Mirage 3 der Schweizer Luftwaffe. Meine Überlegungen hierzu sind ob ich den Rumpf probieren sollte aus LW-PLA zu drucken und diesen danach mit Epoxy zu verstärken, oder doch so wie du das erstellt hast mit der Urform. Das Drucken von LW-PLA Teilen ist ja schon eine Kunst für sich ;-).. Masse, Warping usw. Hast du für den Harrier Jet Rumpf ein Positiv Modell gedruckt oder dieses freihändig oder evtl. mit dem 3D Drucker erstellt? Danke für deine Rückmeldung Gruess

[@renerosentraeger]

Hi, der Harrier wurde positiv gedruckt und anschließend abgeformt 👍

[@michaelmueller9635]

If it's just about the surface and you want to flatten it from the 3d printer pattern, you could use isoprop(anol) + polysmooth.

[@renerosentraeger]

Nice hint, thx 🙌

[@ericklassen13]

Did you ever end up testing the carbon fiber as well?

[@MrAliCAN6566]

Hi Rene, I just come a cross your another video, how are you ? Well, about that fin printing , next time design if you do T (male and female shape plug) on your next design where contact surfaces then, you can simply click them (of course glue it before) then it becomes a solid part and it will be very firm. Just quick reminder ,, take care

[@renerosentraeger]

Very good idea 😁👍👍

[@SwertPertoto]

Rene, would a 5 min (or 30 min) 2-part epoxy work ?

[@renerosentraeger]

30min works. But thin it up with spiritus.

[@kwinzman]

Thanks for the video! Just a nitpick: ground, not grinded more smooth, or smoother, not more smoother.

[@renerosentraeger]

Thanks for improving my english!

[@taxart]

One way to get pla 3d print stronger is to have a bigger nozzle, like 0.8mm and have thicker layer size like 0.4mm.

[@renerosentraeger]

Do you have any experience with that?

[@taxart]

@@renerosentraeger Yes, a lot. Happily sharing experience. Send me a pm.

[@bensonfilmworks7595]

Agreed. It prints very well at 0.8 and .5 mm layer. Surprised. But it seems like the part is heavier.

[@taxart]

@@bensonfilmworks7595 Well, the thinest you can do when it comes to walls and infill is 0.8 instead of 0.4 with a standard nozzle, so you have to compensate the amount of walls and percentage of infill to end up with the same weight.

[@spirit_wolf123]

After all that work to put resin on the part you might as well put fiber I've found it is better to just laminate just like a foam plane. It ends up being a good balance between strength time and cost. One thing to note laminating is good for 2 m or under anything bigger carbon fiber.

[@TheWITTERAT]

Nice

[@KevinMardirossian]

Other than aesthetics, what is the purpose of the filler?

[@renerosentraeger]

UV protection 👍

[@MTBCrafter]

Ist das das LW-PLA von colorfabb? Und mit welcher Temperatur hast du gedruckt? Ich bin auch am Überlegen, mir LW-PLA zuzulegen, aber es ist definitiv nicht das günstigste Filament.

Heads-up grinding means something else... I believe the word you are looking for is "sanding". I can understand what you mean but every time you say grinding I picture you taking an angle grinder and cutting through something. But never the less what you are doing here is "sanding" the surfaces, not grinding them.
