Resin Rules the Nerf Battlefield! Caliburn 4 + Bulwark, Printed + Tested

Is it worth 3D printing resin blasters? Actually, yes!
Everything in this episode* is printed on an Anycubic Photon Mono X 6K and Anycubic Photon Ultra! Get these powerful machines at the best price: bit.ly/3oMIxgB!
Can you 3D print blasters in resin? Ask /r/nerf, NerfHaven, or basically anyone, and you'll get a deafening "HECK NO!" But I'm a cyborg on the edge who don't play by the rules. I printed and reviewed two bleeding-edge blasters, and they didn't just work great in resin... they might actually work better than filament! FIGHT ME DAWG!

The Bulwark is the dual-stage Frontline Foam version, with a 10 dart-per-second pusher motor, double pusher, 3S LiPo, Fang ReVamped motors, and Worker canted grooved Hurricane flywheels.
The C4 is the most current Captain Slug release as of February 2022, with a K25 spring, sussy printed ram core, Frontline Foam black acetyl pusher, and 14" long 0.527" ID barrel.
I wasn't paid or encouraged to endorse anything - my opinions were written after completing and testing both blasters.

The potion seller reference was amazing lol

[@SquirtlePlays]

Be weary of Frontline foam. One guy told me that they ordered a talon claw from them and they hadn't started printing it after 6 weeks. When he asked for a refund they held his money hostage until he threatened legal action.

[@legoboy-ox2kx]

They had really long lead times during the holidays, Derrick even asked me if I would help him out with building blasters part time, but I live in SLC not Provo

[@mhebert350]

not only that but they manage to make 5 errors in 3 orders I pass with them. also their print quality is mediocre at best.

I've had SLA blasters get weak with UV exposure over months that were originally impact resistant. I'd be curious to see this same test in 6mo.

[@joe_ferreira]

We're they painted?

[@matthewd9356]

I'm also curious about this. Maybe have another set printed and coated with anti-UV varnish which might also help a smidge with some of the looseness introduced by being to accurate.

[@Hawk7886]

Automotive clear coat protects against UV and is relatively inexpensive. Would be interesting to try if you're not keen on covering the printed parts in actual paint.

[@ZackFreedman]

Before I actually use these outside, I need to coat them with UV-proof marine sealant. They would degrade if exposed repeatedly.

[@bakedbeings]

Spray paint em!

The grip assembly is still compatible with extension springs if you're feeling picky.

[@Vikinger119]

For the Caliburn collet system there should be a third, intermediate sized o-ring that gets sandwiched between the muzzle/frame part and the collet itself. That system works fine once you put it in.

Wow. I'm genuinely impressed by the amount of accurate resin printing knowledge on display here. I've seen a lot of very knowledgeable youtubers who specialize in FDM 3d printing tackle resin printing for an odd upload or two, and they almost invariably include a lot of incorrect, incomplete, and especially outdated information. It's great to see up-to-date, useful info reaching folks that might be brand new to resin printing as a concept.

[@ZackFreedman]

I appreciate that. I did a lot of research to prepare for this episode, especially about safety and chemistry. I had to cut a lot of it, but there's plenty left for future episodes.

[@JohnTaylorFPV]

Here's something else that works well with resin for me. For any resin parts that rubs against other parts, coat them with some teflon dry lube. It does 2 things, lubricates and keeps the resin from powedering up from friction. Almost acts like a protective coating.

For newcomers and the unaware, Frontline is known to cut corners in their products. Poorly drilled holes, wrong screws, badly toleranced metal parts, the list can go on but ask any FB or nerf discord and you'll hear personal experiences about it.

[@legoboy-ox2kx]

I've been to his store and I don't get what people are going on about. They do great work there, and of course it's never going to be perfect but their 3D printing procceses are good enough, and their blasters function great. Derrick's a cool dude and helps out in the group so much. There's a reason that they've gotten so big

[@N1sm0NIC]

@@legoboy-ox2kx it's a mixed bag. I've heard it all with both store and online orders, the real gripe is mostly non local orders. Personal experience being you cannot print a Zinc lower half on 2 walls and grid infill. It's one thing to have a bad print, and it's another to purposefully print stuff NOT at their recommended settings. And this is not even mentioning the incidents of them not paying their royalties for the blasters they are listing, but that is a whole other can of worms that I won't dive too deep into

[@legoboy-ox2kx]

@@N1sm0NIC I've heard that second story on both sides, and from what I understand that was an issue of communication for the royalties and it was sorted out, he wasn't intentionally trying not to pay. Also, I'm not 100% sure what print settings they use for the zinc, but I've used a few of Derricks and some others he's sold and they've all been solid. Some of the earlier model zincs had issues with the front barrel section coming off, but they fixed that pretty early on

[@N1sm0NIC]

@@legoboy-ox2kx well whatever they're putting out for in store display models/built variants they should that much effort to ALL orders. Like I said, personally I've seen too many fail, all ranging from hardware kits to custom machined parts, and even full built blasters. Had to either fix them myself or point them in the right direction to whoever can fix it (Zinc for instance because my printer does not have the proper tolerances to print them right). In my book they're just not worth the time and money, even if they warranty it

[@N1sm0NIC]

@@legoboy-ox2kx it is nice to hear that royalty stuff is sorted out. I don't know much of it, hence why I wasn't trying to dive deep into that

[@firstnamelastname4224]

[@cyphre]

Reasons nobody uses resin prints for foam blasters seemed pretty obvious: lack of affordable resin printers (until recently), lack of resin printers with enough build volume.

[@littlesnowflakepunk855]

resin is also expensive. 1kg of siraya tech blu is $50, and tenacious is nearly $70/kg. i reckon each of those blasters used at least a kilogram, possibly two or three. basic PLA and ABS average $25/kg

[@BlueScreenCorp]

That Potion's master reference was spot on, this video is a banger!

[@Bacon_Duck_13]

Just a heads up, Frontline Foam has a history of IP infringement, design theft, failure to compensate designers for using their work, parts that aren’t built to the correct tolerance, horrible customer service, and lying about blaster performance. They’re well known within the nerf hobby as a brand to be avoided at all costs. They also happen to support a particular blaster designer, who I won’t name for sake of not stirring drama, who is horrifically transphobic, homophobic, racist, and has been banned from just about every corner of the hobby. I’d highly encourage you support more ethical shops like Out Of Darts, Foamblast, Captain Slug, Silverfox Industries, Orion Blasters, and others.

[@Hawk7886]

Damn, sure glad I saw this. There's no way I'm gonna support bad actors like them. Thanks!

[@grahamturner2640]

Plus, they modify files for some of the blasters they sell (e.g. from what I’ve heard, the Zinc and XC). Hopefully the Woozi is the last thing I get from them, especially since I’ve had worse experience with their customer service lately with my Woozi project that’s still ongoing.

From what I've seen, the tenacious resin is best used to mix into weaker resins to give them better flex and durability

[@ZackFreedman]

It’s a pretty solid upgrade to nearly anything. Siraya assured me that they formulated to print in 100% tenacious, but I’ll be damned if I’ve ever seen anyone pull it off.

[@bakedbeings]

@@ZackFreedman try warming the room to 30C (or putting your printer in a grow tent with a fan heater)

[@BEdmonson85]

@@ZackFreedman it's not difficult, you just have to print it in a hot room, or heat the resin. It says it right on the bottle =P 25C is a minimum imo, but better around 30C. Just don't forget the resin heats up when cured, so if you're printing larger parts the temps will go up after you start printing so don't make it too hot at the start.

[@etch3130]

@@ZackFreedman I have printed some enormous parts in tenacious notably some L shaped pieces 150x130mm they came out completely strainght after about 3 test prints. The most important part is that the part is corrrectly oriented then supported. Not every model can or should be printed in tenacious; its just too flexible for some mechanical parts.
