Title: 3d Printer
Post by: klz on November 17, 2017, 09:30:47 pm
Hello all, I am thinking about getting a 3d printer (Christmas) but I am having a problem finding enough parts to print on places like thingiverse.com I would like to use it for ships wheel, bollards, search lights, life rafts that sort of stuff but dont want to spend hours trying to put something together in a 3d creator is there enough free files out there to make it worth while and where are they I dont seem to be able to find much.

Thanks in advance.

I have a 3d printer, and I am a CAD draughtsman, when I want a part its a matter of moments to draw it up and a few hours to print it. the good bit is that if its been drawn up and is out there, you can easily print it to the size you want.
otherwise I just google the part I want with stl.

try grabcad as well, but the search with the items you mention above (with stl as well) brings up a decent selection.

Thank you for your reply just looking at grabcad now  :}

What scale / size are the parts you want to print?
 
If they are anything close to 1:96 or smaller, then the results from a cheaper filament type of printer might disappoint.  Look into what the printer can do and would you be happy with the finished result before buying.
 
Like Grendel, I too use CAD and Sketchup to produce my 3D models but I send the files to the likes of Shapeways or 3DPrintUK for printing as the parts I need are so small that home printers just cannot cut the mustard.

my model is 1/12 so I can manage with the print quality from my printer.

At that scale these printers are just about ideal I would say.  Maybe even down to 1:32.  Might be a bit difficult at 1:50 though.

at the moment I am looking for 1/12 most my models are in that area, I have just noticed Aldi are selling one from tomorrow any thought on that model?

I have never heard of that one, it looks like minor construction may be required (most require minor or major construction, unless you go for a da-vinci like mine - but then you are tied to their filament which is slightly more expensive)
if you do get one I would love to see a report on its ease of use and performance.

I have done some googling and its a re-badged wanhao i3 plus, it seems to get a resonable review.

I use google Sketchup, which has a warehouse on it so you can download models from there without drawing them. There are also websites like Shapeways that has loads of bits on it and another called thingiverse!

I cant comment on the Aldi one but I have a Prusia i3 from ooznest. It was £450. They don't make it anymore but I chose this as all the electronic boards were made by reputable companies rather than knock off boards from china. My thoughts were that I would be able to purchase new boards and replace components easier as they are available from companies here in the UK. Hope this makes sense!

Does anyone know about obsolescence in 3D printers. There were a lot of improvements in printing materials over the last few years, and this (I assume) affects the type of printer/head that would be needed, and the granularity of the printing area (not sure of terminology) in turn affecting the print process.

Is this an issue? Does this advancement continue at a rate that needs to be considered when buying a printer?

while there are advances, in the affordable range its still extruded filament, or uv hardened resin for your average modeler, there are some new materials, flexible materials, water soluble material (for supports).
one trick, to get abs to stick properly to the bed, create a film over the bed of abs, by mixing some scrap with acetone, to make up a slurry, then spread it thinly across the bed.

I have an i3 I have found it was a bit of a fiddle to get set up ever time i used it.
 Mods
Get rid of the aluminum build plate replace with glass.
Bolted the printer to a 12 mm piece of ply for the base. Now when i use it i don't have to level it every time i move it.
Mix 50% PVA 50% water cote the base before printing.
Now i would look at the CR-10 bigger base. £30.0 will get the extra Z feed kit. Also £50.00 will buy you a blue laser engraver kit for it.
Happy printing.
Regards Andy Quirot

went in to aldi today to ask when they were coming in.......the manager dealt with my request and went to his office and came back out with the latest aldi booklet.......sadly they were mail order only and are now sold out for those waiting for them to hit the stores.

Our local Aldi store had a few in stock last Wednesday, but they were only there for a day. I didn't buy one as I don't have a use for it, in any case, my brother-in-law has one so if necessary I could use his.
