Longer B1 40W - One of the Best Lasers Gets More Power

so I've been a fan of longer lasers for a long time I started with a 5 wat Ray 5 about 2 years ago upgraded to a 10 watt laser then a 20 W Ray 5 and then longer came up with a B1 and I got a 33 wat B1 but they're not done which means I'm not done either this is the longer b140 W laser and it's the subject of this video I'm going to put it through his paces and you can decide if this is one worthy of an upgrade or a new laser if you're looking for a 40wt laser and with that let's get started hey it's Steve and welcome back to the shop now this video should be a bit shorter than a normal review video I would do and that's because I've already covered the longer B1 the 33 watt laser and if you haven't seen that review click up in the corner here and go watch that but then come back because once you know all of the mechanical concerns of this laser uh I want to focus on this 40 W laser module it's actually 44 to 48 watts of power and I'll do some standard benchmarking of course but I also want to compare it to some of the other 40 W lasers I've looked at recently and maybe I'll do a little project just to see how this laser compares to other lasers in the real world and we'll start with the benchmarks so I'll run my standard benchmark test here and you can see the laser working I'm not going to go through all of these tests in detail but you can see there's four of them there's a cut test a material test a gradient test and then I do an image at grayscale and we'll take a look at these results and see what they look like now let's take a look at these results you can see at 700 mm a minute this laser is cutting still really well at 100% power this laser would easily cut at 900 mm a minute that's pretty impressive but what's more impressive is this Square in the lower left corner 70 mm a minute at just 10% power and this laser cut this out this is the only laser I've reviewed that can cut this Square out moving over to the engraving a predictable result here a roughly 45° angle up between light and dark and and uh it it just works the way it's supposed to you can see the 10% line is is dropped out a bit some of that's material some of its power the 20% works well though uh on the gradient side pick a random number for Speed and this laser seems to do it uh seems best around 25,000 millim a minute now if you're wondering what happened to the title up there uh I actually had the wrong title so I re-engraved it that's why it looks a little funny moving over to the image I use those grayscale settings and I engraved this dog now it's a little ragged on the sides and that's because I forgot to turn over scan on but no big deal now I did want it to be a little bit darker uh so I I slowed the laser down and engraved this one and this one looks arguably a bit better somewhere in the middle is probably the right setting but I choose this this image because you can see his dark brown jacket and the darker brown floor uh and you can still kind of make out the the edge of the of the material there so all in all great results uh with Hardware stored plywood that's not a bad achievement so I'm pretty happy with how this laser works so the results are in for the 40 W longer B1 and they're predictably good I'm not surprised but if you were buying a B1 and you're on the fence between the 30 watt laser and maybe spending the extra money for the 40 watt you know which one should you do well I I did you a favor here I pulled the 30 wat uh results from the tests now they aren't exactly Apples to Apples but if you look at the cut test for example on the 30 wat at 300 mm a minute you're up to 50% power before you really start cutting by contrast on the 40 W it's 30% so definitely much more power so if you want a cutting laser the 40 W might be your choice now on the engraving side I didn't do a a a standard engraving test again I was testing differently back then but I did a a gradient test and if you look at this gradient test test and I believe I called it out in the video back then I ran into a few problems because the gradient the grayscale on this laser on the 30 watt wasn't as good you could see it was white and then there was almost no transition to Black on the gradient and as a result when I looked at the at the dog image that I engraved there I actually dithered the image because I was having this grayscale problem so it looked like a good image but dithering is kind of cheating and that laser wasn't really as good at grayscale certainly as the 40 W so if you want to do high high speed cutting or or grayscale engraving you're probably going to want to lean towards the 40 W now let's compare this to some of the 40 W lasers that I've reviewed recently and I'll just stack them up here and I'll start with the longer b140 Watt on the bottom and there's the cut test compare that to the the creality Falcon 2 it's virtually identical and then the X tool S1 and you can see see that one's not nearly as good at cutting then I'll look quickly here at the engrave test there's the B1 you can see the Falcon 2 the engraving is not nearly so nice and the S1 uh isn't quite as clean either so definitely I would call the B1 the leader in in the engraving tests and finally we'll look at gradient tests here for comparison there's the B1 uh just for reference by comparison the Falcon 2 looks pretty bad and that's because you have to cut it down to half power the X tool S1 is comparable to the B1 it's a $2,200 laser and the B1 is is keeping up head-to-head and the B1 is actually probably a marginally better cutter so keep that in mind now all this extra power comes at a price so you might want to hold on for a second the longer b140 watt is currently on sale for $1,255 by comparison the 33 w version of this laser is only $950 so there's $300 difference now if budgets your your a concern then you might want to lean towards the 30 W one you know it's it's up to you but if you're buying a 40 W laser anyway you're going to be looking at this laser this longer B1 and comparing it to things like the creality Falcon 2 the creality Falcon 2 is currently on sale for $155 so it's $200 cheaper and you might say okay why would I buy the longer B1 versus the creality well there's a couple reasons first of all the laser speed is better on the on the the B1 it's 36,000 mm a minute compared to 25,000 mm a minute and the workspace is bigger it's 450 by 440 compared to 400 by 4115 mm so it's up to you they're reasonably similar lasers but I personally would lean towards the the V1 in this particular case so take that for what it is and make your choice so that's the 40 W version of the longer B1 it's it's definitely a step up from the 30 wat comes at a price of course but you get better cutting you get better engraving and you get proper grayscale image engraving that was honestly a bit of a struggle on the 30 W laser so you know if you were in the market for for a 40 W laser for this specific one I'll put an affiliate Link in the description down below and uh definitely put this on your list if you want a 40 W laser I'll put a video up above go watch that and uh I'll see you over there and get out there make your world and I'll see you next time
