Reply To: Is there a way to rough up the print bed safely?
Good to know – thank you.I’ll refrain from using sandpaper (or anything else) on it again, so long as it continues to “grip” the print job against the print bed. I’m 8/8 of my last 8 print jobs, so...

The reason I set the base so big is the reason I bought this printer was to be able to build in the entire space so I wanted to test it’s capabilities. Most of what I am printing most likely won’t even...

@jkao in your other posts you use TAP plastics pigment at 0.5% by volume. http://www.tapplastics.com/product/fiberglass/resin_fillers_dyes/tap_premium_pigments/50Is that your current recommendation?

@kevinrau You’re right, I hear it’s damaging. But the VAT is otherwise useless because the teflon film was kinked. I bought the materials to pour a new silicone layer and apply a teflon film when this...

In general, the standard practice for all resin based stereolithography machines, both laser and projection based, is to rotate the part, usually something like 10-40 degrees in both of the X and Y...

I believe I’m now up to 11/11 successful prints in a row (all different objects, by the way) – and with the hard VAT at that. Each time, I’ve been changing the exposure time lower (on layers 2 to the...

You can try reducing your exposure time somewhat, but it’s a delicate balance between reducing light bleed without reducing part hardness below the threshold necessary to hold the part together during...

Also, 0.5% is a good starting point that won’t overpigment resins that already have pigments in them. Some people have gone even higher in order to achieve higher detail.

Thank you Tdixon1000. I’m going to try to get a sample and experiment with the Color Con formulation you suggested: Color Con MD-1364-NR NT12 BLACK. Couple of things during this long print, I broke it...

Thought I’d add that I Use a triple balance beam and input 1 to 2 percent pigments by weight vs volume. It’s easier IMO to add by weight if you have an accurate weighing mechanism and helps with having...

I tried some black Colorcon ink in it, I don’t have an amount as my scale did not pick up the small amount, just a tiny amount that still yields a transparent part but turned the orange to more brown...

During the days I tried stirring the resin, I could never continue to print without making some sort of visible line at the mix location…I wanted more turn key to start and walk away until finished…The...

After three thousand layers, I wasn’t able to get the part to keep printing. I was printing this part at 50µm and after the second set of layers, the part ended up going up to a random Z height that...

The only solution I can think of is to at this point run a long full print of the remaining shaft like object but do this in 3DM-ABS. I like 3DM-ABS as it’s able to not settle for 12 hour plus prints...

@tdixon1000 – you got down to 2.5 second cure time per layer – but what were your XY and Z microns? Without those, we can’t get a benchmark if that’s good/ok/bad.

James, I was trying to explain that after you print say that to do the multipart print I had a total of 4700 layers. I put only 1500 layers in the model folder and printed these. Then I would put in...

Tdixon1000, thanks for that advice. I’ll call them today and see if they’ll part with a sample bottle of the ink. Much appreciated. Also the I remember you were experimenting with another mixture for...

I was printing with X-series and finding over time even though it has toughness it would slowly deform under load, changing it’s original printed shape and failing to hold a weight, once relaxed it...

I see. So the only problem is that the end-of-print raise sequence lifts the Z level to a height that you can’t jog back down to because the amount is not a multiple of 0.1mm?If that’s the only...
