B9 Creator v1.2 HD - Red/Cherry 1:1 Mix test

[alanbuttler]

Hi all,

 

After a week or so of tinkering I've had my first successful print from a B9 Creator v1.2 HD.  This model is capable of 30 micron xy axis, though with quite a small build area at that resolution of 57.6 mm (2.67″) x 32.4 mm (1.28″) x 203.2 mm (8.0″).   By tilting your 3D model you can however print slightly larger objects.

 

In September I'd had Tebee's Welshpool & Llanfair Beyer Peacock & Co 0-6-0T printed on a Statasys Objet Edan 260V, at 200 micron xy and 16 micron z.  I figured this print would set a bar to measure against once I'd got the B9 operational.  So far, with a little more tweaking I think the B9 comes out better with less striping and improved detail, the material is also much tougher.

Some jewellers on the B9 Creator forums have been having good results with a 1:1 mix of the B9 Red and Cherry resins, so that is the material I've started out with at 30 micron XY and Z.  Over Christmas I'll be trying the same print with pure Cherry and Spot-HT.  It's been quite a learning curve to get something productive, mainly because a UV filter hadn't been removed from the projector assembly which meant to get anything to print I had to use much higher exposure times.  Thankfully B9C support were able to quickly identify the issue and from that point onwards I've been able to print using default settings.  I think I'll try for longer settle times on the next print as I think these will help to reduce some traces of lines in the print where the resin has been curing as its still settling.

Not bad at all and a nice prototype to boot! I've been using the Spot HT resin mixed with 0.125% black pigment which has been giving me some good results. Not tried Cherry or Red yet but having seen these I think I might just give them a go once my machine is back in business again judging from your prints!

 

Just for interest, I've attached a couple of pictures; the first is pure Spot HT resin and the (almost) completed model was done with the Spot HT/Black pigment combination (sorry it still needed a little work to get it sitting level on the chassis).

Nice one Steve, just had a look through your site, you've been busy! Some great models on there. I've got some Spot-HT, I'll give it a go with the same design in the next week or so, I think the PDMS can just about handle another..! On that note, have you seen these NuVat's that have been developed recently? Seems to be a glass replacement for the PDMS, it's been tested on jewellery sized pieces, sounds quite promising!
