So, spent some time to designing a holder for the E4 so I can use it to image my PCBs.
3D printed a first attempt yesterday and based on that design I made some tweaks/changes. The new version fits nicely and I created a slot to allow a velcro strap to fit through.
Sure, please post the files - who knows when they might come handy
But right now I'm more interested in details about the 3D-printer you're using - the resulting quality seems to be really good.
Ok, Sketchup/STL files attached. The only potentially tricky part is to find a hardware store that sells the 1/4-20 nutsert. I had a few from a bunch of years ago laying around - amazing I could remember where they were.
The 3d printer is a makerbot replicator 2. It does manage to work reasonably well most of the time (phase of the moon, goat blood etc). My initial problems were to get the print to stay 'stuck' down to the work surface. We have 2 glass sheets 1/4" thick to print on. A decent coating with cheap hair spray seems to be the 'magic' to make the initial layers stick down, if they don't, the model warps or comes off completely during the print. The other issue is that sometimes the extruder stops extruding the molten plastic - I assume the extruding tip gunks up or something - certainly the filament roll is free to rotate.
These 'home' quality printers have quite a ways to go before I would consider purchasing one. Once some 'real' companies get into the act then the quality should increase enormously. I look at current 'home' 3d printing equipment as the equivalent of the early days of inkjet printers - either super expensive high end units or consumer level stuff that had clogged inkjets 2 out of 3 times you tried to use them.
Once companies like HP, Epson, Canon, Lexmark etc get into the home 3D printing then we'll see equipment that works reliably and produces quality with durable plastics. It just requires the mainstream companies to determine whether the size of the 3d printing market is large enough to justify the R&D to provide the products - bit of a chicken & egg though.
Most printers right now use PLA which is a great plastic to 'print' with, but can be awful in terms of real world use. PLA has a glass transition point of 60C (great for printing) which means if you print something and leave it in a hot car on a summer's day it WILL deform... ABS is the other common plastic (approx 100C glass transition point), but it can be more problematic to print with and requires a heated work surface to prevent peeling/warpage. The higher end printers use various other plastics/resins and better extruders or lasers for curing/printing.
Anyhow, the 3D printing is fun and the tool flow is pretty easy. Sketchup is free and after a bit of a learning curve is pretty easy to get a model drawn up. A free plugin for Sketchup allows an STL to be created and then you have a standard file format that can be fed into the 3D printer software to slice it for printing. Hopefully in another year or two or... we'll have better consumer level AND sub $1k 3D printers available and improved higher temp plastics to choose from.
