Re: Dying PLA/ABS/Nylon - 11 years ago

Hello I was giving a general look at this forum and I think it helps. I have no expertise in chemistry, but it looks very interesting. I have the following idea and if someone from the forum can help me with this reasoning, it will be good. It is as follows: Using a good UV resin or for use with blue light, very reactive immediate application of a compound of powdered ABS, nylon or PLA, and this

Re: Visible Light / Near UV curable resins - 11 years ago

Hello guys .. This forum helps me a lot and keeps me updated, thanks to all. Is it possible to transform a liquid or viscous these resins cited in this forum to one or more types of powder, as is the need on the grain size? Thank you. I await answers. I think it will be great if we can have a photosensitive resin powder, grain varied and that works well in the length of blue light, as this color

Re: Old SLA resins - 11 years ago

Hi .. I also think this is the best way for the future of RepRap 3D printers. Just think resins that harden with Ultra violet light or blue light, may be worked better from powder particles, it will be easier to develop a print nozzle more efficient way compared to today as it is cured. Think about it. The grain size may be of varying sizes as may be applicable to each type. If you h

Fabbing and sintering objects from different materials - 11 years ago

Hi .. I've been reading the comments above and am also very interested and curious about all these possibilities. I lay in Chemistry, but I've been thinking and I think the Sugar, water (distilled, burricada) more any type of alkaline liquid (alcohol, methanol or other) may be useful for the production of 3D parts the method Ultra_Violeta. Perhaps even more with the addition of a thin resin plus

New SLS Co2 laser 3D Printer - 11 years ago

Hi .. Researched so far, you just need a laser beam up to 1000 Watts of power (without lens) and a means of distributing the powder, either polymer or metal, which is larger as the temperature of these material, the lower the power requirements of the laser. Among polymers and metal powders major differences exist and need a very efficient device for controlling the laser, from 20/50 Watts for f
