My single diodelasers have 5 Watts, but the fibres are combined pairwise, so with a combined pair i have 10Watts.

I have to check when receiving a complete pumping unit vor salvage - it's possible, that two pairs are combined to 20 Watts too ...

For really high powers with diode-lasers you can even combine much more (80+) when focussing them in a ring-array - look here fo a sample ... but this is high-tech, so not suitable for DIY ...

Another methode is to use small collimators (e.g. 5mm in diameter) for the single fibers, arrange as many of them as possible parallel in the diameter of a plan-convex focussing-lens and you'll have all outputs combined in a single spot ...]]> VDX General Wed, 17 Feb 2010 03:38:08 -0500 https://reprap.org/forum/read.php?1,35281,36391#msg-36391 https://reprap.org/forum/read.php?1,35281,36391#msg-36391 -------------------------------------------------------

Simple thermodynamics- dTemp(barrel)/dt is proportional to Tnichrome - Tbarrel, so if Tnichrome = target temp, Tbarrel will asymptotically approach it but never actually achieve it, and if Tnichrome = target + 1, Tbarrel will take a long time to reach target, but if Tnichrome = Tbarrel + lots, Tbarrel will reach its target quickly at which point the closed loop control kicks in.]]> Triffid_Hunter General Wed, 17 Feb 2010 01:59:56 -0500 https://reprap.org/forum/read.php?1,35281,36373#msg-36373 https://reprap.org/forum/read.php?1,35281,36373#msg-36373 -------------------------------------------------------

In the past i built 3 lasercutters for cutting plastic-foils and thin sheets with sealed RF-CO2-lasers from 3 to 5Watts power, worked with some comercial NdYAG-lasers, welding- and pulse-lasers from 10 to 30Watts CW or 2kW pulsed ... and have now a 50Watt fiber-laser and a 1Watt diodelaser working at home and are busy applying the exhausting/filtering and implementing the lasers as tools in my CNC-programs.

In the next days i'll receive some 5Watt-diodelasers for testing with low-power-sintering and designing simplified modules aimed as changeable toolheads for rerraps/repstraps/CNC-mills.

But until now i know only a handfull of people i can commit such a dangerous tool ... and most of them are in my location (Germany)

But on the other side you can buy a ready to use cutting laser with a 60Watt-CO2-tube off the shelf or in ebay if you're over 18y ... no other terms ...

So it's maybe only the organisation of some local centres for teaching the know-how and handling? ... maybe the LRUG's are a good starting point?]]> VDX General Tue, 16 Feb 2010 15:34:41 -0500 https://reprap.org/forum/read.php?1,35281,36331#msg-36331 https://reprap.org/forum/read.php?1,35281,36331#msg-36331 -------------------------------------------------------

you are probably correct. Someone posted an alternative method here recently that I liked a lot. You apply a sintering inhibitor for each layer and then swipe a heater like a halogen lamp over the layer which fuses it. this avoids lasers yet comes with many of the benefits of the laser process. One nice thing with lasers is you can do metal parts if the machine is enclosed and new atmo pumped in...but we are a long way from that here.]]> maitri982 General Tue, 16 Feb 2010 15:04:50 -0500 https://reprap.org/forum/read.php?1,35281,36328#msg-36328 https://reprap.org/forum/read.php?1,35281,36328#msg-36328 -------------------------------------------------------

I don´t think so.
I found it trivial to design a new head for the RepMan
but the mounting on the RepRap is just tiny.
Nothing but an extruder or a very thin device fits there.
I´m still wondering how Bogdan managed to do his Flex-Shaft
milling-head with the flex shaft comming out between the top
2 bars.

And I certainly don´t see any automatic toolhead-switching as
the mounting of the head requires screws to be turned.

I have a larger printer and can use only a fraction of the space

concrete. (A PourStrap is a RepRap made with a mold rather than a
thermoplastic extruder. This is true even if you RepRap the molds first.)

It is a beautiful concept, including fun things like papercraft or
laser cut sheet-molds.

*Please remember to take off your jeans before filling them with cement. :)

---

Technical issues (this is all guesswork on my part, I'm no expert):

Hydrostatic pressure

Epoxy and concrete has a high hydrostatic pressure and will burst
through where you have sewn if you have tall column of concrete. This
may be true unless you are using generic firehose-canvas used by
firefighters.

The seams are not as much of a problem as the holes where your rods
and static parts (fixtures, through holes, embeded nuts) are. Those
holes in the fabric will be difficult to seal properly, and material
will ooze out. You can seal them from the inside with modeling clay.
... You can frantically patch leaks from the outside with modeling clay.

Your second mold will have many less leaks than your first mold.
If you are lucky, you will not end up with a 50 kg pair of pants
epoxied to your workbench or floor as a permanent desk ornament.

Geometry and mechanical degrees of freedom

If you are making a monolithic PourStrap, you have a number of
fixtures and rods, and you need to align them with 1-2-3 blocks, lego
bricks, masonite or steel pegboard, etc. (In which case you might
make the mold from pegboard and food-type plastic wrap rather than
fabric.)

If you are making a Lots-of-Parts PourStrap, like a Mendel clone,
Darwin clone, Eiffel Clone, Delta-clone, you need each poured subunit
to have 2 geometric ... "constraints"? 2 through-holes, 2 flats, 2
fixtures, 2 embedded nuts, 1 embedded rail + 1 throughhole, etc. Call
it 2 geometric "features".

Because if we describe the Lots-of-Parts PourStrap as a 3D mesh or
graph located in space, even if it is made from toothpicks and
marshmellows, each marshmellow has 2 toothpicks and is connected to 2
marshmellows. (Ignoring 2 end marshmellows).

Locating and controlling the orientation of those 2 features requires
pegboard, 1-2-3 blocks, or RepRapped thermoplastic molds or fixtures
(rod holders).

You get 1 free flat area at the top of your cast, where gravity makes the top of
the epoxy "perfectly" flat. But you need jigs and fixtures to locate
and hold a rod at a specific angle and location with resepet to
to this flat area.

One thing you need for a pourstrap is a plastic drafting triangle,
T-square, and lots of shim stock. Maybe a straight edge. Or a full
machinist toolchest, if you have 100-500 dollars of measurement
technology on hand.

---

An octopus or hermit crab uses optical control and feedback (aka
looking and correcting movement) to specify where the toolpoint is
moving, and doesn't need 2 geometric "features".

Since most RepStraps are dumber than hermit crabs, I think it is
necessary to build in precise geometry.

I apologize for not really understanding the real technical issues or
mechanical engineering to describe the geometry requirements better.

---

I think a monolithic or lots-of-parts Eiffel is the best way to begin
with PourStraps. Right now the best design is lots-of-parts and
lots-of-metal-rod. I think that is a little silly, but it is the best
working design we have, and ships well via the postal service.

... not moulds ... i think you know the air-inflated 'jump-castles' where children can crawl in and jump over the elastic/springy basis and against the walls?

A similar concept but redesigned for an inflatable rerpap-frame with some support-structures ... all made from sheets of fabric or plastic, glued or sewed together to represent the 3D-structure when pumped up or filled with a fluid but hardening material ...

So you're working only with flat sheets, cutting contourlines, combining the right pieces along the outlines ... and when inflated - voilá! ... a 3D-structure :)-D

... some time ago i saw a report where airplane-wings were made from carbon-fabric: - first cut the exact contours, then sewed the parts together, inflated, impregnated with 2K-epoxy, cured and last trimmed/milled for fitting.

Has anyone thought a similar strategy for building a solid frame?

I've been thinking about an Eiffel / RBS PourStrap with large [[RBS/Beams]] of steel or sheets of acrylic to make the mold, and using food-type plastic wrap as a release element.

Or laser cut sheet for molds. Or CNC router made molds. I think about molds a lot. And self-replication a lot. That's why I like the idea of using [[RBS/Beam]] for as a mold to make [[RBS/Beam]]. Or using [[RBS/Beam]] and large sheets of acrylic to make a [[PourStrap]]. Or using a [[Laser Cutter]] to make a [[FlatPack PourStrap]].

You can inserting some stiff plates and fixatures for mounting the additive components or mill the fitting areas after curing ...
I'd definitely go with with embedded fixtures or RBS-holes. Milling is a bootstrapping problem.

I think a separate section of the wiki is a great idea. I am enthused about some of the directions things are taking.

I had thought of an 80/20 prepacked as well, but perhaps now I don't have to worry about it thanks to goinreverse. The nice thing is there will still be room for people to innovate within whatever design we start with using extruded T's.

As I previously stated, lasers provide great promise to solve several key FDM problems, so I am glad to see progress on that front as well. The sintering inhibitor process is also interesting as it may achieve similar results with no needed laser.

If some of these designs can be multi-tooling...even if its just:

* High accuracy FDM
* CNC
* Pick and Place

Then you may have a device that can have a real impact on the world in a positive way. if we get lasers working too then that would be a real coup.

Of course each step presents difficult challenges, but getting a good solid structural design of T-channel with solid electronics should accelerate needed improvements as this is very flexible framework to work within.

Just post the parts list and specifications in detail. That way individuals can acquire the parts completely independently of you and you won't incur any liability. Mouser, Digikey, Alltronics, Mcmaster all sell heaps of dangerous parts that when put together can become even more dangerous, there isn't a big issue because they sell it as parts (also for example makerbot sells unassembled parts). Just search instructables and you can find about 10,000 things more deadly than what we are talking about here where the primary risk is blindness or fire (though the extruder is a major fire hazard itself, probably more so).

Wickedlasers here in the US has fair pricing for reasonably high quality laser eye protection.

That fact that we all already play with suspect electronics connected to 900F nichrome wire, I don't think I really see a laser as being any more dangerous than that. I think the main danger is that people think if they can't see it it won't hurt there eyes which isn't true and as long as that info gets out there accidents can be avoided.]]> goinreverse General Fri, 12 Feb 2010 04:52:25 -0500 https://reprap.org/forum/read.php?1,35281,35909#msg-35909 https://reprap.org/forum/read.php?1,35281,35909#msg-35909
I think the start could be in English ... in our German CNC-forum we have some serious disputes regarding lasers and security, but most real work is done beside the forum in P2P-networks and small 'closed' groups with 2 or 3 persons, so this actually isn't a point to worry about legal stuff.

But this will change rapidly, when the kits are in the wild ...

I'm glad to hear that 8020 (and the other extruded-aluminum "ExAlRap?" folk, presumably) are so organized. This means that once folk have developed and documented, it will be super-easy for you and other folk to do up and sell a 'ExAlRap' vitamin kit.

Personally, I need to design, do, and document Eiffel and RBS before I can get into 8020.]]> SebastienBailard General Fri, 12 Feb 2010 03:27:01 -0500 https://reprap.org/forum/read.php?1,35281,35896#msg-35896 https://reprap.org/forum/read.php?1,35281,35896#msg-35896
I am still working out what media and formats I am going to be documenting with but I have no problem whatsoever with it appearing on the reprap site and will most likely license it under creative commons SA which I think is compatible with repraps documentation license.

There should be a pretty foolproof 8020 repstrap coming from me forthwidth. I am talking to them about making it into a kit (they offer that as a service for pretty nominal fees) that you can just direct order through any of their distributors and it comes flat-packed, pre-cut, etc in 2-3 days flat. Just add water, err electronics and motors.

As a side note they are outstanding folks over there at 8020, one of the easiest industrial companies I have ever had the pleasure of working with. I should say I work for a business that is likely to do some large volume production with them on other things but my guess is that they would be just as nice to anyone off the street. If you are in the West US I would also strongly recommend copper state nut & bolt (an 8020 distributor).]]> goinreverse General Fri, 12 Feb 2010 02:43:03 -0500
