Plastic Cannon??

Hi, I'm currently in Year 10 and we have been assigned to make a USB lamp. Now, I'm fine with the assignment only I cannot think of how to shape my idea realistically. I wanted to make a cannon shape, with a sphere like bottom before it curves into a thin neck. However, I don't know how to make the plastic bend into the sphere like shape. It's really difficult and I'll include a picture of my idea if it helps!

Plastics in the Automotive Industry

This isn't an in-depth tech article or anything but it's interesting to realize just how much the auto industry runs on plastic: http://www.paxonplastic.com/the-automotive-industry-welcomes-a-plastic-future/ I even read that a 3d printed car might be hitting the market as early as the end of this year. Not sure if that's just a rumor but it doesn't seem far off.

plastic/metal tube branding?

I am looking to brand my own products for my store. The products are small tube batteries about the size of a sharpie's body. They come in two materials, a plastic/rubber material that is difficult to scratch/dent but has a soft feel and the other is a stainless or anodized metal. I see two possibilities for branding but need help figuring out how to accomplish the desired effect. 2) I transfer my logo onto the tube by rolling it over a stamp with an ink/epoxy of some sort ( *magic ink* product unknown)\ 3) I get decals printed/made and transfer them onto the material. I don't know much about decals or permanent printing liquids, and would like to hear from you what you think! Please check out the attached picture as well

Other media besides plastic?

So I recently started looking into some of the 3d printing stuff as a way to make a number of laboratory items that are not easily had other ways.  While 3D printing seems really promising, i'm noticing there's not alot of work being done on non-plastics. Are there resources out there for 3D printer enthusiasts who want to use metal or ceramics in there creation?  Off the top of my head, i can think of a few ways that they could be encorporated into an existing 3d printer (metal and ceramic powders in a wax binder that can zapped with a laser to fuze it into place), but I'm only just barely getting into this and i'm really not looking to reinvent the wheel simply because i didn't know that it's already been done.  If plastic went entirely by the wayside, pieces that could be cured in a conventional oven could be printed, but fully cured, ready to go products are sorta the point of a 3d printer.

Moulding plastic - for a knife handle or holster ??? Answered

Hi ... I would like to ask fro help to find the proper ENGLISH word/name for what I'm looking for. I would like to make a plastic handle (for a knife) and a holster. My grandpa had a stuff for this, where he moulded it, put the metal part of the knife handle inside and left it to become hard. I have found something like the POLYMORPH but I'm just a little bit concern - wouldn't it be to soft ??? Or the low melting point ??? The stuff that my grandpa used became hard as a rock. And when you wanted to remove it, you had to break it ... and it breaks exactly like rock, glass (it wasn't soft). Thank you in advance for any suggestions.

Hi all ! I want uncolored plastic, or uncolored latex, and I need to know how it's possible. For have light color, pastel color. Like nightblue => lightblue. It's used for cleaning old yellow plastic, like old white or grey computers or consoles, but it's maybe only for have the origin color, not for uncolored the color in the mass. It's yellow because the plastic is oxyded. With hydrogen peroxyde + UV. So, do you know if this combo is good for my project ? Or who I can make it ? It's for custom parts. With many friction, and it's bad to use paint for that. Hope yoou help me, see you soon. Thanks in advance.

What type of plastic should I use for heat forming??

I need help selecting a type of heat-forming plastic. Can any plastic experts offer advice? I'm nearing the end of the design phase of a project, and I need some help selecting the right material with which to make it. I'll essentially be building a solid, 3-dimensional form by setting a plastic sheet over the form and hitting the plastic with a heat gun, and then trimming. Are there any plastics that would "droop" onto the form when heated, but stiffen up again properly when they re-cooled?  A pliable, but still fairly rigid plastic that resembles the stuff those cheap black plastic oil receivers are made out of would be ideal.  If this type of plastic exists, where would I get it? Also, what thickness would be best? I would like it to be as thin as possible, but still function as described above. I have looked into vacuum forming, and while AMAZING, it is too expensive/difficult for my purposes.  Any advice??

Electrically Conductive Plastic: a general discussion.

I find i have an odd set of interests. Specially with regards to this forum.  I'm interested in electrically conducting plastics. I've been hitting the Wikipedia pretty hard looking for information on the topic.  I've found a couple of interesting articles:  http://en.wikipedia.org/wiki/Polythiophene http://en.wikipedia.org/wiki/Polyaniline My main reason for pursuing this as of late is because I think electrically conductive plastics offer a way to create high efficiency photovoltaic cells on the cheap (least relative to growing pure Silicon crystal without oxygen contamination).  Azodyes, which are popular doping agents for current thin film photovoltaic cells  can be linked directly to the organic back bones of the polymers, and i think this will make the conversion of photons into electrons more efficient. There's other organic compounds (specifically i'm thinking of metallocenes which can be used to generate positive valences, also known as "holes" within the molecular structure of the plastics) which can be used to dope an organic solar cell, but azodyes are the most obvious. Anyway... gonna hit up google. if any y'all have ideas post em up.

Identifying plastic so I can weld a repair

I am repairing a broken wheel on a old lawnmower for which spares are not available. The hub (holding the roller bearing) has broken away from the rim and tyre. I've managed to weld the two parts back together using the hot air gun on my rework station but some small pieces are missing and I'd like to replace these and reinforce the welds by adding material.It is possible to buy rods of different plastics to carry out these repairs but I need a better understanding of the material I'm working with. It is an opaque white plastic with a greasy or soapy feel. It melts relatively easily (I used the heat gun at 180 degrees C) and bonds back to itself well. I suspect it is a polypropylene of some flavour - straight Polyprop, HDPE or LDPE.I don't have scrap material to test without removing some from the wheel. Any thoughts on what it is likely to be and do I have to know exactly which it is or will the different materials bond with each other?

Good type/thickness for a clear acrylic sheet which may(will) be taking occasional impact? Answered

I've got a martial arts gym setup in my basement, and we're tight on space. There's a lot of stuff I have hanging on the walls (sword racks, training pads, weaponry, the like) and I'm looking to put up some acrylic sheets or something similar, hinging up at the ceiling, so that that stuff is protected, and more importantly, that if a sparring session gets a little wild, nobody is going to get thrown against a wall of (potentially sharp) gear.  Home Depot sells acrylic sheets, and I'm thinking I can fashion something workable to support them, but they're not super cheap, and I don't particularly want to waste money on something that will break the first time someone bumps into it. Any ideas? I'm not springing for bullet-proof glass- lemme rule that one out. TL;DR: Impact-absorbing clear plastics, sold in ~40"x~20" sheets?

For emergencies or simple application: how to make your own nuts out of (p.e.t.)-plastic bottles:take a bottle (#1 plastic, preferably smooth, w/o imprinted patterns or design etc) > cut off bottom and neck > start cutting (scissors) > the resulting ´tube´ into a consistent (width, depending on desired usage), slightly diagonally, thus sort of ´peeling´ it > wrap the strip around the screw/threaded-part/etc you need the nut for twice (for a start) > ´melt´ the edges of the wrapped part = joining them (i use a little solder-iron) > this way the wrapped beginning of the strip wont come loose > ´brush´ with the solder-iron (or whatever other source of heat) over the wrapped part (w/o) burning holes in it > this causes the plastic to shrink and press down into the thread and adopt its shape > once set keep doing more wraps of the rest of the strip until you reach a desired diameter > now, again, join the edges of the wrap with heat, and afterwards brush again over the outside of the created ´nut´, so that the plastic shrinks down & compacts > after having cooled off: unscrew the ´nut´ with pliers > ready for useps this is just a simple sketch. got no camera to take photos. sorry. so, please, ask whatever if you got any question. and any kind of feedback is more than welcome. bowing.

What is the melting point of molded plastic epoxy ?

Hello. I would like to know what is the melting point for most integrative circuits epoxy molded plastics ? The kind of plastic I am talking about would be the ones used for BGA chips found in smart phone IC's (integrative circuits). I would think that a decent powerful household kitchen microwave should have enough power to melt this type of epoxy material used for BGA IC's. I would like to de-cap the BGA. PLEASE note that I will be using a cheap throw away kitchen microwave to melt the IC and the BGA is not important even if the heat generated damages the die layers made of silicon. This is strictly for hobby purposes. The same question but does anyone know what kind of metal is the bottom part (the tiny metal circles ie solder balls) of a BGA IC made from ?

Adding Other Materials to the Mix

Over the past couple of years, I've evolved from being totally captivated by my 3D printer, making everything I could think of out of the three plastics I can print with, ABS, PLA and Nylon, to having the Replicator, sitting in my shop and becoming "another tool".  A tool that stands in as an "employee", who can make things while I do other things. Along with doing a pretty good job of making my designs, I've experimented with stepping in, during the print, adding components made of other materials, such as cloth, metal and other plastics.  I've successfully made pulls on tie bags, an electric push button, aluminum mounts for my project car and spring clips to hang my wife's potato chip and popcorn bags in the kitchen. Has anyone else been able to use their printer to make items, not 100% plastic?
