Re: Up! mini - perfboard

The method I use to check the nozzle height is to look at the "nose wipe" that the printer performs before printing. This comprises of about 1 1/2" of material laid down as 2 tracks on the left side of the platform. Each of the two tracks should be about 2mm wide when printing at 0.2mm. This indicat...

Re: Disconnecting USB cable

Re: Printing at lower temps for aftermarket ABS

I agree ABS is the best material for most purposes, it has a better feel, is less brittle and does not bio degrade. However there are a few engineering instances where PLA wins out. I needed to make a threaded support inside a petrol (Gas) filler pipe. ABS won't crack it as ABS goes floppy near such...

Re: A love hate relationship

Not sure if this observation may be valid. I bought an UP! late last year, have put about 3Kg of ABS through it, only about 500grams of the OEM, the rest is mainly natural with some black and some safety red all from 2 different UK suppliers. The reels are marked Makerbot. I print large and small, a...

Re: UK Filament suppliers?

Hi, I have a standard UP printer, with filament feeder. (Only mod is Drew's extruder arm design) Had a friend mill me one. Try Robosavvy at http://robosavvy.com/store/index.php/cPath/2003_2008. They carry a large range of 1.75mm ABS and It has all worked for me (The spools are marked Makerbot.) I bo...

Re: Make your own Paint (Uk users only)

Just tried Lego, whilst it works, dissolved in MEK it is not as good as I expected, So I guess I will just start building Lego models with what I have left.

Re: Painting models

Just tried Lego melted with ABS. While it works I would say that the dyes used seem to remain as fine solids in the MEK solution. (Some colours only) This gives a "gritty" look to the finish. Has anyone tried pigments intended for colouring polyester GRP resin, will they dissolve in MEK/Acetone or m...

Re: I want to buy another 3D printer

Hi Wackojacko, OOOOOPPPPSSSS, I reckon the Saturday night beer session got to me. I just checked my Kapton tape, it is NOT 120mm, I think that was my desire, it is in fact 80mm (Ebay item 170886075546). I use a centre 80mm then 2 x 30mm to fill the plate. Sorry to get you excited. Must remember to m...

Re: I want to buy another 3D printer

A minor correction to Julia's comment. You do not need a glass plate for Kapton tape. I print ALL my objects on Kapton tape laid direct onto the UP black plate. The only thing to remember is to wipe the shiny back of the Kapton tape when you first use it, as it has a molecular layer of release subst...

Re: I want to buy another 3D printer

The UP printer may well meet your demands. I have made parts that are mechanically strong (bearing Slides for print industry printers) and items that are left exposed in gardens. PLA is biodegradable and somewhat brittle so is not really suitable for your purposes. The UP printer is designed, primar...

Make your own Paint (Uk users only)

Hi, Just a thought, I recently bought a pack of Lego (made of ABS), to make some paint by dissolving the Lego 50:50 in MEK or Acetone. Of course I have far more Lego bits than I need. So is there anyone in the UK who would like to buy off me some packs I could make up. I am thinking of 50 gram packs...

I note the Upers section of the this forum also has a wish list thread. Is it possible for the manufacturer to advise us if they are acting at some time in the future on any/all of the issues raised. It would be a shame if others looking to purchase a UP printer read through this site, see the issue...

Re: Painting models

As mentioned in other threads on this subject. If you want to make your own ABS paint in many colors, buy some Lego bricks and dissolve them in acetone or MEK, Lego is ABS.

Re: Why is this not working?

The latest UP software will sometimes convert from mm to inches and vice versa. So if you have exported to STL in inches the UP software may think it is mm, mm is the default dimensions for the UP. To check open the scale option in the UP window, you should find a scale by 25.4 and scale by 0.3937. ...
