Styrene Tutorial Guide basic intro plastic model making modeling tips and tricks (Part 1)


my name is Eric Strebel welcome to
another video of mine about industrial design whether you’re designer or a
model maker and you’re just looking to make high quality models something
beyond a paper model that you may normally make styrene is probably a
great choice it comes in tons of different varieties
thicknesses and shapes flat stock mainly but you can get it in sheets and rods as
well these sheets here they come a little bit
textured so it gives you a little variety it’s not just smooth so if
you’re looking for some sort of a texture finish or something like that it
also comes in a clear and you can get a lot of this stuff at a good hobby shop
or on eBay it’s sold all over the world you can also vacuum form styrene quite
easily it’s a little example of some vacuum form wheels that I made out of an
old European coke bottle around 1995 vintage something like that these wheels
were cast into a male model meaning it was sticking up and you can see the
definition on the one side is much better than the other here’s some simple
forms these were machined out of rennes something i just modeled up in the
computer infusion for another project and I had a machined out and then these
are some of the ensuing blanks they were just used to paint color onto
them for color samples here’s a quick example of vacuum forming and process
this is me just drawings down some heated styrene over a male model we suck
the air out of it any forms to the shape it’s a very simple
process once it cools you can cut it up and use it for whatever project you’re
working on as I noted earlier it comes in
rods and tubes of all kinds of variety not usually in color like the flat sheet
stock does the neat thing about some of these tubes is that they are made to
slide into each other so you can easily make like a little hydraulic jacks or
Rams stuff like that but it’s really easy to form and get some tube shapes
evergreen is a popular supply place here in the United States any good hobby shop
should have that you can certainly search for ebay or amazon for evergreen
you can get what you want also in metric sizes any sort of a model
kit that you see in your local store hobby store is also made out of styrene
so those pieces will work with your flat sheet stocks when you glue them together
either using a solvent weld or super glue this inal acrylate something like
that this is a quick example of a model that I built out a starring a little
solar charger and it’s used to simulate the final product show material
thickness it’s very easy to make a functioning model out of styrene the
petals on this solar charger here where a vacuum formed first that’s what you
saw before in that vacuum forming video and then they were laser cut out so
they’re all the same and then it’s all assembled and easy to make a functioning
working mock-up now the PVC piping that you can buy at the Home Depot also comes
in larger tube sizes really readily available here in the United States you
can theoretically also use that and bond that to the styrene you should be able
to use this glue if not superglue should work just
fine the beauty of that is it’s readily available there’s tons of different
glues as well I’m showing you the two in the can are very thin like water and
then you can get the thickened stuff here I put it on my hands
it’s just thickened version of the other stuff and it allows you to not have the
glue run all over the place for some people that’s a little bit easier now
applying this glue is fairly simple you could use a brush like I have there on
my cutting mat but I prefer to use a syringe it allows me to control where
the glue is and this is the reason I like this system is that I use these
luer lock syringes just like they use in the hospital allows you to use whatever
tip you want these are all blunt tipped needles meaning they are not pointing on
the ends so they work out really good for applying glue they come in different
gauges you can put them onto a squeeze bottle like I have there I also happen
to sell those on eBay as well you can look for them there the beauty of this
system is that I can just put in whatever material that I want into the
squeeze bottle or the syringe and then if I need to change the tip for a
different application I can just go and switch out the tip very easily now some
good tools to have for cutting styrene or just model-making in general one a
scalpel I like it to make curved cuts and then have good standard exacto blade
I like the kind that you twist tight on the end that have a little bit more grip
through the middle they hold the blades much better when
you’re cutting styrene just a couple of scores on the styrene and then you can
bend it over and it breaks right along that score line it’s quite easy to do
that I use that cutting mat to help me cut the pieces straight the other option
is to flip the blade 90 degrees and you’ll actually gouge the styrene
and you can break it off I like using a file to straighten out and flatten the
pieces you may also need to take the burr off the edge of the styrene as well
and here you see me doing that just scraping it with an exacto blade to get
that little burr off the edge from the cut I like using a file because the file
is already flat and straight doesn’t usually get gummed up or clogged up like
a piece of sandpaper I use a file that’s flat on one side and then has a curved
surface on the other and allows me to also sand or file curved surfaces here
I’m placing the partic on a piece of wood just to help me stabilize the piece
and get good even pressure across the piece of styrene the other option of
course is to use a piece of sandpaper here I think I’m using about a 180 grit
piece of sandpaper on top of a piece of wood of course so it’s flat because the
object is to get the styrene flat so that I can bond it nicely to another
piece of starving another great little tool is these little files nail files
you can buy them at your local beauty store or you can make your own little
piece of styrene or plastic and I spray mount some different grits of sandpaper
to those strips so I can make my own and I label them so I know exactly what grit
sandpaper is just great for taking off the little burrs and rounding corners so
now let’s actually glue a couple pieces of starring together I take my syringe
with my blunt nosed needle in there and I insert it into my can and I just suck
up a little bit of solvent into the syringe it doesn’t affect the syringe
once I’ve got my two pieces prepped I’m doing it on a piece of wood because the
solvent will eat away my cutting mat the grid you can see where it’s already
started to dissolve I’ll put a little bit of the solvent here on the edge and
you can’t really see it but it’s actually dripping down this edge and
it’s coating the entire edge and basically softening the plastic so I
then take the two pieces of plastic and I put them together and the solvent
literally melts the styrene at a molecular level and it creates a fairly
tight strong bond instantly it pretty much sets
it’ll take a full let’s say an hour for the solvent to evaporate and fully cure
but you can get something quite nice so the beauty of that is of course is that
glue isn’t squirting out all over the place that’s quite thin here I’m just
gluing a couple pieces together I’m going to drill a hole in that flat piece
and glue the two pieces together now if you don’t want to solvent weld it or you
don’t have that stuff you can glue it together with see a sign alacra laid and
the stuff in the blue is the sun’ll acrylate the stuff on the right and the
brown is a kicker it kicks off the sign alacra laid much
faster so you don’t have to let it dry you can put a little drop of that is on
the drawback of that of course is that it gums up the sandal acrylate and it
doesn’t always make the most beautiful joint the best joint you will get will
be with the solvent weld that kind of covers the styrene model
basics I’m gonna have another video after this where I’m actually going to
get Bosch a quick model together out of some different plastics including the
styrene and just show you how quick and easy it is to model something up using
different plastics don’t forget to subscribe to my youtube channel below

  1. 7:37 I need to glue two pieces of plastic together and it needs to be a strong joint. I've tried superglue and Araldite without success. Will that Solvent Weld do the trick, or is there something even better?

  2. Hi, I can't work out what the two types of glue/solvent you are using are. All I can read is 'Acrylic' on the tub. What kind of glue should I get, please? Not just the brand (as I live in the UK and it might not be available here), but the type of glue.
    Many thanks.

  3. At 3:13 the flower opens and folds can someones explain the hinge mechanism please ould love to use this for a project

  4. Thank you for the vid! So many useful things can be made out of scrap material. BTW, I am always in search of some solvent or adhesive suitable for those "difficult plastics" such as PET bottles (polyester, mylar) ands their caps (PP? HDPE?). Do you know any? Thank you!

  5. You should tape the corner together dry before you glue it, then you can be sure its square and straight. πŸ™‚

  6. Hi, great tutorial. I don't have a vacuum forming machine but do have a rough 3d cardboard shape that is made of strips to create a curve. Can i use styrene sheets and a heat gun/hair dryer to form over my 3d form to create a smoother curved piece, or is it easier to use strips of 2mm plasticard and sand the edges round like half a ball? Thanks in advance.

  7. The down vote is in protest of the all to rampant use on YT of unnecessary, annoying background β€œmusic” that serves no purpose whatsoever other than to make it harder to hear voiceover or to unsuccessfully hide overmodulated or other amateur audio quality like on-camera mics.

  8. i'm wondering whether using a "warm" to "hot" lacquer thinner in an airbrush to chemically etch in lieu of sanding would work well.

    i'm a beginner car model builder, and am finding that complete body sanding is a chore i'd like to avoid, if possible.

  9. GREAT VIDEO!!! Thank you for the helpful tips!!! Do you know how to bend / mold styrene plastic? As for scratch building models?

  10. I know I'm late to the party here……but I just stumbled upon your channel Eric………one thing you and your viewers should know……..Evergreen makes virgin styrene………other MFG's might not produce virgin styrene………becareful with what you buy.

  11. Is 1.5mm to 2mm styrene sheet easy to bend to shape at room temperature without it breaking? And if so does it hold that shape ok?

  12. Thank you for this posting.Β 

    To my fellow hicks I recommend a good art supply store. I'm amazed at the access to materials and techniques they offer. Also, often well-hidden urban plastics supply houses have been accommodating of my need both for specialized materials and advice.
