For a long list of epoxy benefits, it has one main drawback, which is toxicity and it has a cumulative effect like a dose of radiation. This may...
I just mentioned the shrinking issue in another thread. Depending on the type of polyester you are looking at 2% or more of linear shrinkage...
It has been a while since starting this thread, wish the progress was a bit faster, but nevertheless, I am still happy there is a progress and it...
4mm plywood and pour-in polyurethane foam. Only it may not be comfortable to seat as you will lose some legroom
In my experience, something that originally comes as a simple idea once being implemented becomes an increasingly complex project with a ton of...
If finishing the surface on a one-off mould or plug, would it be any easier to get the shape and surface with the mould/plug and work out the...
Few thoughts on the mould function Let's look at two extremes. 1) They build one-off boats or prototypes without moulds and arrive at a fair and...
let's zoom in and try to understand the objectives of a mould and how PE system suits them from a rational point of view: 1) we want a good...
epoxy can be UV stabilized, but the above is in the context of a mold, so UV is not a concern. tooling surface coat is epoxy version of gelcoat,...
it is about hardness and abrasion resistance of the surface coat, regular PE needs additives to increase those, but epoxy is already sufficiently...
right, styrene vapor is 3.6 times heavier than air, good point! I positioned my exhaust intake up above thinking the incoming cold outside air...
Does it mean that as long as the hardener remained sealed and resin crystals are melted, the epoxy is most likely to be good enough? ;) I have an...
My printable volume is 30 x 30 x 32cm, printer itself was $300, material is $16/kg. The cost of plug surface formed by the printer comes...
Now we have several scenarios: 1) resin from a trusted supplier with accurate datasheet but that is beyond its shelf life 2) some fresh resin...
off-topic, but on the subject of plugs... I started with EPS for my plugs, then switched to XPS, and then realized the 3D printer beats me in...
it has been a while since I looked into that foam. the deal there was that it is the same physical foam as what Diab sells as Divinicell but cut...
The point is the structural engineer comes up with a laminate schedule for the project sorely based on the properties of the materials. The...
The flexural modulus test is about controlled breaking of a sample and measuring the braking load. Using the known dimensions of the sample and...
these fellows do miracles with EPS: www.youtube.com/user/adenHynes/videos
structural properties of epoxy are measured by several parameters, which can be quantified and are declared in the product datasheet. while...
