Request Sample

Hello everyone,

Actually, I am really interested to buy a new 3D printer such as Mendel one.

However, I am really doubt about its quality.

You know, AFAIK, there are architectural and engineering project that demand a high resolution, good quality and finishing.

Please take a look at below image for an example of high resolution 3D printer work:

And if anyone here don't mind, I have a 3D part as a request to be printed by Mendel 3D printer itself, to see whether Mendel 3D printer is suitable for me or not.

Please see the attached of the 3D .stl file and a screenshot of it:

Unfortunately the RepRap is a rather low-end printer. While the output is amazing for the price, it is not capable of producing anything quite like you've pictured, at least not without a lot of post-print finishing.

Edit: I would look through Thingiverse to see examples of what can be done.

A lot of those pics are from the ZCORP machine which uses powder.

You can if you want to, use a small nozzle, in the region of 0.25mm dia as opposed to 0.5mm dia standard.

Makes sense. I though those looked way too high resolution to be FDM produced.

Yeah... powder printers produce a lot weaker parts, though, from what I've heard. I guess it depends on if you want accuracy or strength when choosing between FFF (FDM) and powder.

Please read the following before judging the print

I have only been at this for a few months and I am not very well versed in Skeinforge settings yet.

This is the first time I've printed a part using support and I seem to have overdone it bit. The mesh is probably double what it needs to be..... made it rather hard to remove and leaving it looking a little ragged. Given a little time it could be cleaned up to look much better.
Although hard to see in the picture the slotted collar printed quite well.

The machine itself had no problem printing the spines however the extruder was not appropriate for that application. It has a large melt chamber designed for printing at high volume (not so good for starts and stops) and the nozzle at roughly .37 mm was a bit too big for the job. Together they left the spines looking pretty blurby. Just to say: The poor quality of the spines was the result of poor choice of hot end and not a limitation of the machine. A slightly smaller nozzle on a smaller more articulate hot end would have produced a much nicer print.

I just bought some .2 mm drill bits, maybe I'll give it another go

It seems to me that that part would print with less support material if it was turned upside down. Those parts that look like bristles would act as support.

The print result turned out very well IMHO.

Hi Bruce, that looks really good for just 2 months work, well done.

That actually looks very nice! I think you're right that with a .25 mm or so nozzle and a small melt chamber you could probably print the spines very nicely.
