Re: 3D Printed Speargun (Inverted)
Quote:
I do agree 3D printing is the future, either consumers will have one or will just go to a local Amazon outlet that prints stuff on demand although I don't know if it is just around the corner. Definitely in our lifetime, though. Large scale injection molding usually involves CNC aluminum and equipment that is cost effective for runs in the tens of thousands. The muzzles aren't injection molded (everybody assumes they are), the process is closer to the way custom parts are made by hand for the medical and film SFX industry, using older techniques that suitable for runs in the dozens or low hundreds.

Re: 3D Printed Speargun
ARTIZ Fantástico
Is long enough, hard and tough the plastic 3D printer? <º))))))>< <--------------<< ¿Es suficientemente duro, ligero y resistente el plástico de la impresora 3D?

Gracias por su comentarios Ramón . He estado usando los 3 cañones prototipo durante el verano sin ningún problema en todos por lo que el plástico impregnado con carbón es de hecho lo suficientemente fuerte ... su duración es otra cuestión de rutina. Thanks for your comments Ramon. I have been using all 3 prototype guns over the summer with no problems at all so the carbon impregnated plastic is indeed strong enough... how long they actually last is another matter of course.

Re: 3D Printed Speargun
The Polycarbonate 3D printing filament has been a total success... the strength of the material is no different to a manufactured plastic speargun handle... you can throw it around in much the same way. Printing did take a little while to workout with the Polycarbonate filament from Polymaker called PC-Max. The real breakthrough came when I used a new printer bed adhesion called WolfBite MEGA It completely eliminated all the warping problems and made using the polycarbonate filament so much easier to use. My prints below are very low resolution and were relatively quick to print at 10 hours either side... does mean a bit of post print work but the finished article is everything I could have ever hoped for. I am close to finishing off this 'traveler' version with the break down Riffe shaft... which is fortunate because I leave for the Med on Saturday to begin my round the world trip. The Riffe shaft is a bit long (and expensive) but it was the only one I could get at short notice... I'll put some images up of the finished version broken down for packing into my rucksack and then fully assembled if I get time. As you may have guessed I've given up on the aluminium version for now... just too technical for me to get detailed casts with the basic equipment I was using... I'll wait until I get to the far east and see how possible/affordable it is to get it made over there. I am also considering publishing my designs online so that others can download and print... any chance I could get some feedback on this please. New Poll thread here...

Re: 3D Printed Speargun (Inverted)
Glad to hear that filament worked out okay. The Wolfbite stuff really works, particularly their nylon formula. Previously I had tried pva, garolite, superglue, none were anywhere near as good.

I also had big problems before WolfBite and eventually broke my heated bed glass using a polyurethane glue so I know exactly what you are talking about. |

Re: 3D Printed Speargun
I think you explained this in a previous thread but you are putting a prebuilt SS mech into your handles (like the kind that goes into a routered grove in a wood stock)?

Re: 3D Printed Speargun
I just chanced on this thread, https://forums.deeperblue.com/thread....102131/page-2, so this 3D printed gun project, as expected, is something that has taken some time and effort where you have maintained a firm goal and realized it by working steadily towards it. By the way the inefficiency of coil sprung energy storage due to coil buckling and rubbing on any guide tube that supports the spring makes it a poor choice for a speargun. It was used at the dawn of mechanical spearfishing as the spring conveniently fitted in the guide tube for the spear.
The spring gun was taken to its most refined form in the Hurricane "Carabine", but that was an expensive side-track that had already been obsoleted by the pneumatic speargun, once the latter had finally been rendered pressure-tight! |

I did give up the spring idea pretty quickly by the way. Last edited by artiz; 10-27-2016 at 02:39 PM. |

Re: 3D Printed Speargun
ARTIZ 3D print amazing carbon fiber parts. Markforged gives you parts you can’t create on another 3D printer.

I took it back within 14 days and exchanged it for an Ultimaker extended... each to his own though! |

Re: 3D Printed Speargun
SketchFab 3D model here! Latest iteration now printed in very strong/durable CarbonX material. This printing filament also enabled me to design/print my wheels/pulleys with their own bearings inside... still to be fully tested yet though. The cost from a 3D printing service called Innovate 3D was $250 delivered to Thailand from the UK. Much cheaper for anyone who already has a 3D printer which is able to print using this or similar astonishingly resilient and reasonably priced filaments of course! It has taken a few years but prices for printers which can now print using Carbon Nylon mixes are becoming available at a much more reasonable cost thereby opening up the ability to 'home manufacture' our own strong and durable designs/working parts for spearguns and their unique requisite forces and conditions of use! Not before time as far as I'm concerned though! Rigging this up is proving to be a little bit challenging but I am obviously working at a snails pace anyway... I will eventually post up further trials/tribulations which I manage to catch on pics/video! I have now completely sealed this first Carbon Nylon (PA12) version with a polyurethane varnish and silicone gap filler incidentally! Last edited by artiz; 10-04-2021 at 06:38 AM. |

Re: 3D Printed Speargun
Handle looks good, muzzle... not so much! But I understand an inverter requires to have the pulleys and all that if you want to pack any power within such a small package.
Keep up the good work! Mikel |
