Velleman Buildtak 3D Print Bed Surface for K8400

I bought this as a last attempt to get anything usable out of some Hobbyking polycarbonate I bought on sale a while ago. I'd tried glass with various adhesives at ever increasing temperatures but the warping was always too much after a few layers and the prints peeled right off. Having seen Polymaker sell Buildtak with their PC filaments, I reasoned it would be a good option for my more generic stuff. Adhesion to the PC was excellent. First trial was on a raft (also often recommended for PC) at 140C bed and 280C nozzle. The part stayed stuck (there was major delamination further up the thin-walled part, probably due to low nozzle and chamber temperature) and the raft peeled off the surface with a little encouragement. The second attempt was a small Companion Cube straight onto the surface at 130C. That came out as well as any filament would, which was great, but the nozzle was set a bit close and removing it took a chunk of the sheet with it. Fortunately it wasn't in the middle so I have plenty of usable area and this was my fault. It does mean this experiment was a success and I can now print the toughest rigid plastic fairly easily! This particular sheet seems to be good value compared to other build surfaces on Amazon. The text and logo are actually translucent, not white. I haven't yet used it for any other materials as I prefer my tested method of 3D Lac on glass.

I think it sticks to much unless you have a spatula on hand

STICKY STICK STICK STICK! This thing is unreal! before this I was using masking tape and it was always a challenge, but now I just hit print and walk away, no problems whatsoever. Installation was a doddle, I just removed my bed, stuck down the Buildtak surface and trimmed the edges. For the screw mounts I sliced a cross though the Buildtak with a scalpel and simply reassembled as normal. Works perfectly! I'll definitely be buying this in the future.

I'll preface this by saying the buildtak worked well, almost too well for the first few prints, adhesion was excellent, if not a bit difficult to remove from the platform. The biggest problem with it however is it's total lack of instructions, application was fine but when it comes to cleaning it, it's super easy to ruin it. I used a very small amount of isopropyl alcohol on a cloth to lightly wipe it down and now nothing will stick to it at all. There are no warnings or instructions packaged with it, and after much googling I found buildtak's support page that states not to clean it with anything stronger than rubbing alcohol. That's 13 quid wasted.

This is just the right size for 3D bed, Mine is made of Aluminium, Warmed it up a bit, And this sheet of Buildtak is held down firmly. And flat, If you place the sheet, in the incorrect position, It will not come off easily. UpDate this Product did not last Very long. Very hard to get the 3D print, off the Surface. It sticks too well, Damaged the surface of the of the pad.

My buildtak failed after 5 prints. It's amazing at sticking down prints but getting them off is horrendous! When I pulled the object the plastic buildtak came up too and bumps appeared. Unusable now!

I have purchased two of these now. first one I did not do a great job of fitting and had a few bubbles. I left it on and glad I did, this is one of the greatest surfaces for 3D printing. Adhesion is great and using PLA not bed temp required. I replaced only because I accidentally scratched the surface deeply and this carries to my printed object. Great Item and will continue to buy when the next one gets broken by me.

This was sorely needed! Having bought my printer, I found the hotbed came with painters tape on it. It lasted one print before I had to replace it and was using a glue stick to help adhesion. Soon got fed up with that and decided to purchase this item, and I'm very glad I did - it has proved to be a great addition to my printer - no more bumps affecting my prints, and no more sticky fingers! Highly recommend!

Works well with Anet A8 Prusa I3 3D printer. Hassle free, no more masking tape and hair spray, worth the investment.

Ich benutze diese Bettoberfläche nicht mit einem Velleman-Drucker sondern mit einem Anet A8 (Prusa i3) mit beheiztem Druckbett und es funktioniert trotzdem sehr gut. Die Fläche haftet enorm gut am Bett, weshalb man beim Aufbringen vorsichtig und genau sein sollte, da man kaum eine zweite Chance hat das Teil wieder unbeschadet abzunehmen. PLA haftet sehr gut daran, ABS habe ich bisher kaum ausprobiert. Man bekommt die fertigen Drucke trotzdem recht gut von der Fläche, notfalls hilft man sich mit einer Spachtel. Man sollte allerdings aufpassen, dass der Druckkopf sich nicht direkt am Druckbett aufheizt oder sich dort länger an einer Stelle befindet, da die Fläche auch nur aus Plastik besteht und bei Temperaturen von 200°C punktuell anschmelzen kann. Ist mir leider gleich zu Beginn passiert, da ich einen Druck kurz nach dem Start abbrechen musste und vergaß den Druckkopf sofort beiseite zu schieben. Nachtrag: Vorsicht, wenn man vor dem Druck eine Lösung aus ABS und Aceton auf die Oberfläche schmiert, um die Haftung des ABS-Drucks zu vergrößern! Die Oberfläche verträgt offenbar kein Aceton, sondern löst sich darin. Habe das herausgefunden, weil ich die getrocknete ABS-Flüssigkeit überhaupt nicht mehr entfernen konnte. Deshalb habe ich das ABS mit Aceton lösen wollen und dabei die ganze Bettoberfläche glatt gerieben. Außerdem ist sie nicht mehr schwarz, sondern weiß und man sieht die Wischspuren.

mes prints ne se decollent jamais, super adherence meme sur petite surface. je recommande fortement ce produit qui regle definitivement les problemes de decollement

Es una PEGATINA, SEMI-RIGIDA, de 25x25, que se pega a tu cama caliente (o a tu cristal) para conseguir adhesion del material de impresión, sin mas. Funciona muy muy bien con PLA y PETg. Con ABS hay que tener más cuidado y hacer un buen "SKIRT" bien amplio, pero pega. Con PLA la adhesión es simplemente espectacular. Sin lacas ni leches. Me gusta muchísimo, y queda hasta bonita. Viene sin ningún tipo de instrucciones. Cuando lleves varios usos, es recomendable limpiar con alcohol y pasar una lija fina por toda la superficie de la pegatina para limpiarla.

Eccoci di nuovo nel mondo della stampa 3D, avevo già acquistato questo tappetino adesivo per la stampa3D. La prima esperienza era stata positiva, ma l'avevo utilizzato direttamente sul piano di metallo della stampante, ma dopo test prove e informazioni condivise con altri appassionati, ho scoperto altre potenzialità. Ho riacquistato il prodotto per un utilizzo più intensivo e soprattutto incollandolo ad un piano in vetro borosilicato (Pirex), e qui con una superficie veramente piana ( il piano in metallo si dilata e si imbarca con il calore) il vertex permette di stampare anche parti di dimensioni al limite del hotbed, senza problemi di adesione e di movimenti del pezzo. Assolutamente consigliato per chi vuole passare da scotch/lacca o problemi di adesione ad un qualcosa che permette di avere il massimo dalla propria stampante
