Are there any disadvantages to 1.7mm filament? Their site makes it sound like it is an improvement over the 3mm.by TheFerminator - General
There is one available here: I am thinking of getting their single extruder for the printer I am designing. They have the option to have it preassembled for an aditional $10. They are just getting started and are in the preorder stage at the moment. Being preassembled you would just have to mount it level to your bed.by TheFerminator - General
Does printing a raft not allow you to remove the cardboard from the part? As far as other base materials are conserned you could try unfired clay. Once clay has dried it is very porous(some more so than others) and will easily disolve in water. I would try one from the stoneware category, they are the roughest and most porous. Earthenware and porcelain would probably work also. Just add water toby TheFerminator - General
How strong is the power supply you are using? I remember seeing somewhere that you need 4.5 amps for a basic printer and you should add 11 amps for a heated bed. Based on that I have calculated that that you need around a 200W power supply with a heated bed.by TheFerminator - General
Could layers of conductive paste or gel be extruded between layers of ABS to make printable electronics? I was thinking something like the biomedical stuff available here:by TheFerminator - General
I saw a youtube video of someone extruding solder into chanels whith a RepRap type printer. Would it be possible to extrude a metal by heating it enough to soften it, but not completely melt it? Or maybe have a cold bed so it solidifies on contact then the next layer heats the last just enough to bond?by TheFerminator - General
No matter what you use to disolve the cardboard you are going to either end up with wood fibers or pits where they used to be. If you want a smooth finish on the bottom I would add an extra layer or two on the bottom and sand/cut them off. Maybe you could print a crosshatched pattern first that could be peeled off of your actual part? I don't know how else you would remove the texture.by TheFerminator - General
I might try a delta later on if I have a place to set up a permanent machine with a large print area. They look like they would handle that well.by TheFerminator - General
just soak the cardboard in warm water untill it is very soft. peel off what you can and scrub the rest off witha a sponge.by TheFerminator - General
The delta looks cool, bit it seems like it would be harder to control movement(mainly stay on a level plane). I am also trying to design a collapsable, portable printer similar to the on Ben Heck showed off at Maker Faire. I don't think this would be very easy to do with a delta. It looks like they take up a lot more room hight wise. Those videos did give me a good reference as to the capabilitesby TheFerminator - General
Thanks, that is exactly what I was lloking for. How much slower are threaded rods than belts, and how big of a cost difference is there? I was planning on doing all three axis with threaded rods, but if I can find reliable belts for cheaper I would probably switch to just using threaded rods on the z axis. Is there a good web site where I could find threaded rods and belts for a good price? I amby TheFerminator - General
Hello, I am currently working on designing my first printer. I need some help deciding what to use for the movement systems. I have seen a lot of pictures of printers with threaded rod systems, but also some with belts. Can someone give me some tips as to the advantages and disadvantages of each. In my head it seems like the threaded rods would be slower, but more acurite(depending on the threadiby TheFerminator - General
