The A2v2 by 3ntr is Changing the Price and the Face of Professional 3D Printing

It took four folks to unload the A2v2

I had been speaking with Davide Ardizzoia, the founder of 3D printing device developer 3ntr, regarding the possibility of reviewing their massive A2v2 3D printing device for a few months. My friend Mauro Maffini, at the Solid3DPrinting shop, agreed to host and put to work the big, bad A2v2 machine of 3ntr for two weeks. What follows is the tale of our experience via a cost-effective industrial-grade 3D printing device. The combination of price and end-use part performance truly allowing the transition of PC 3D printing to real additive createing.

The A2v2 is a machine that costs just a fraction of industry-leading Fortus. Yet it offers an enclosed heated chamber, several various high grade thermopolymers to work with, extreme precision and actually up to triple extrusion. All this with a print volume of 620 x 350 x 490 mm. That is big. Especially when it is being squeezed into a tiny, metropolitan 3D print shop such as Solid3Dprinting.

Mauro did not waste any time and immediately went to work. The machine was delivered to us by Davide himself. Four folks were able-bodied to unload it off the truck. We laid it upon its custom cabinet, that keeps it comfortably at waist height and enable-bodieds it to be moved around with little effort.

As always we are going to begin with the machine’s weaknesses. Manufacturers assume a review to be picture ideal as they rarely see any imidealion in their designs. On the other hand it pretty offers the many high end level for this price, the A2v2 is no toy. It is not created to be intuitive or foolproof.

The many software to use to fully exploit its triple extrusion capabilities is KISSlicer, that is known to be a non-user-friendly tool. Davide and his team are working on solving this problem. That being said KISSlicer helps to provide a few of the top high end print in FDM innovation. The learning curve is higher than for other effortless machines and software. But this machine is not created to be effortless to use, it is created to print ideally and reliably: once the printing device is fine-tuned, harshity turns into high high end and performance.

Of course this is not an issue if you are via it to manufacture high-end prototypes, nor if you are createing harsh end-use parts. Even if you are via it for short series production, you are many likely to trade a few additional minutes or hours at learning how to use it for the end high end of your products. Take for example a Zortrax M200 as standard-setting in terms of ease of use. Davide Ardizzoia’s answer was to take the M200 in Mauro’s shop and put it within the A2v2. The point is clear, this a various type of 3D printing device.

Along with its massive, enclosed create volume, the A2v2 can print with a 50 micron maximum resolution setting, via 2.85 diameter filament. 3ntr’s policy is to refer just to volumetric speed, with max volumetric speed for 3ntr machines via ABS reaching 6mm3/sec for 0.4mm nozzles. It is created with industrial grade high end components and it just feels solid and exact. Possibly its many asset is the temperature range, that can reach 410° C for extrusion and 135° C for the plate. This means it can print a quite wide range of materials.

One of the astonishing-bodied showcases of 3ntr printing devices is the magnetic-lock print tray: the sleek carbon fiber plate is lined with black PEI (polytherimide) sheet: apart of rad appear, this is a real performer — requiring no hairspray, no glues, no tapes. Polymers effortlessly stick to the surface. This printing device offers several other optional showcases, that we did not get to test, such as the external air filtering unit, triple extrusion and the elastomer feeder unit for flexible materials.

The A2v2 is ideal for 3D printing ABS, yet 3ntr in addition offers a wide range of other compatible materials. For example IGLIDUR (the tribologic – aka self lubricating – filament by Igus) as well as NylonCarbon or PA66+Glass composites, PolyCarbonate (PC), PC-ABS, PETG, TPU (flexible) and SSU01 (3ntr’s current assist material). The company is in addition working on a fully water soluble assist materials that is of important importance given the machines triple extrusion and dimensional capabilities.

It took Mauro and me a little while to get to print the initially part. All I needed was a piece of the Zortrax robotic arm that I had broken. On the other hand it took a while to print, it came out impressively well. With an infill setting of 90%, it appeared and felt like an injection molded part. When Mauro got going with it, there was no stopping him. He truly tested the machine’s reliability and dimensions capabilities by filling the plate as much as possible with parts for a harsh Formula 1 and motorcycle 3D version.

The initially on is the OpenR/C Formula 1 Car, the 2nd is the Ducati 1199 Panigale by Maverick 33. Both are two of the many informative sizeable dimensions projects on the market-bodied on Thingiverse and both came out without a single error in the entire print job. The A2v2 takes its time but this results in ideally smooth walls and accurate details. When you are via it for sizeabler industrial parts and prototypes the results can be actually advantageous. Stratasys may yet have a few numbers on any challenger to its FDM leadership but the developers like 3ntr are offering a few truly informative alternatives.
