insutama Posted June 25, 2017 Share Posted June 25, 2017 Hey everyone im back and recentlty got a 3d printer does anyone know of any usefull tools or powder scoops that i could i print Link to comment Share on other sites More sharing options...
PyroFrank Posted June 26, 2017 Share Posted June 26, 2017 I have a 3d printer too and just successfully printed my own hemisphere molds- 1.75", 2.5" and 3". No more buying hemis for me! I used abs plastic and it worked great for holding up to the stress. I also made a 6-pin mini star plate, but have yet to try it out. If you are interested in any of these things I would be happy to send you the models I created. Here's my hemi molds. I acetone treated them so they would be smooth and release better. 3 Link to comment Share on other sites More sharing options...

lloyd Posted June 26, 2017 Share Posted June 26, 2017 I'm late in this. However, it seems the "tools you should make" are "the tools you need". Go from there! Lloyd Link to comment Share on other sites More sharing options...

Those are good looking molds. I just had a quick question about how how they work. Are they the type where some number of layers of patterned pieces paper/chipboard/strawboard are sandwiched together between the female and male parts of the former? I normally see pieces shaped somewhat like snow flakes or an asterisk used. Link to comment Share on other sites More sharing options...
lloyd Posted June 26, 2017 Share Posted June 26, 2017 (edited) Mumb, those 'snowflake patterns' are called "gore patterns". They're similar to the designs necessary to make hot air balloons. I recently made one for a client from PVC sheet as a pattern for manually cutting gore sheets for testing various papers for making shells. It's a chore, cutting enough paper by hand for making a shell, but a valuable capability if you wish to evaluate many different papers.

insutama Posted June 27, 2017 Author Share Posted June 27, 2017 what i would love is a tube roller made from a 3d printer i would pay for the .sti file. I still find rolling good rocket tubes quite a challenge Link to comment Share on other sites More sharing options...

Are they the type where some number of layers of patterned pieces paper/chipboard/strawboard are sandwiched together between the female and male parts of the former? I normally see pieces shaped somewhat like snow flakes or an asterisk used. Yes, exactly. I sized and printed a snowflake pattern to cut the layers as you described. I use 2 layers of corrugated cardboard and 2 layers of kraft as laminates on the outside and inside of the hemi. Not the fastest process, but I can make one in 15 minutes including cutting time, and I am very satisfied with the quality. what i would love is a tube roller made from a 3d printer i would pay for the .sti file. I still find rolling good rocket tubes quite a challengeI could probably help you out with that, I've become pretty proficient in solidworks. Is it just a rod with a slit along the side of it? If you needed something more specific you could make a rough sketch and some dimensions. Link to comment Share on other sites More sharing options...
insutama Posted July 1, 2017 Author Share Posted July 1, 2017 im not exactly sure to be honest i have seen a few in action on youtube however they all seem to be 3 metal rollers and 2 sides with some groves for the rollers and a slot to move the top roller down or up.

Maserface Posted July 1, 2017 Share Posted July 1, 2017 I've got a motorized tube roller, and except for a few parts, the whole assembly would be easier, stronger, and cheaper, using traditional machining methods. Mines mostly aluminum, little bit of steel, couple plastic gears, and a motor Link to comment Share on other sites More sharing options...

BlueComet24 Posted July 2, 2017 Share Posted July 2, 2017 This sort of circle cutter works pretty well for cutting cardboard and paper disks: https://www.thingiverse.com/thing:189956Also a hand drill is nice for having more control while carefully/slowly drilling out passfires (seriously, go slowly!) or drilling though tubes and nozzles with no live comp around without having to use an electric drill.https://www.thingiverse.com/thing:792988 Link to comment Share on other sites More sharing options...
Maserface Posted July 2, 2017 Share Posted July 2, 2017 Where did you buy it from ?I bought it from a friend, who built it for himself. He no longer is actively doing pyrotechnics (he keeps busy with oil painting and hobby machining). I bought it for three reasons, one because I was already getting some stuff from him (the lathe he built it with), two to learn how to build a better version, and three to roll tubes!! When I get through my list of projects, I will take it apart, measure everything, and release plans to build your own 1 Link to comment Share on other sites More sharing options...

Arthur Posted August 17, 2019 Share Posted August 17, 2019 While it's a chore to cut hemi blanks manually hemi factories will use huge power tools cutting several sheets at a time punching with a sharp tool to get hundreds of leaves per minute.

Bigmark Posted August 29, 2019 Share Posted August 29, 2019 What would you guys say is the easiest to use printer for sarting out. Out of the box and ready to run. Link to comment Share on other sites More sharing options...
Jandabuilders Posted August 30, 2019 Share Posted August 30, 2019 Hands down the Ender 3 from Creailty. It’s cheap compared to others and preforms really well out of the box. Some tinkering can be expected to achieve optimum performance, but it will produce great prints regardless. There is a slight learning curve when leaning 3D printing though, however there are lots of great forums online to help. You do have to assemble it once ordered but that isn’t really complicated and there is a great deal of YouTube videos about it. Link to comment Share on other sites More sharing options...
