But I’ve picked up some valuable insights along the way that I’m excited to share with you.

Pre-Print Preparations

The key to successful resin printing starts long before you hit that print button. Proper preparation can make the difference between a stunning model and a blob of half-cured resin stuck to your build plate. (Trust me, I’ve had my fair share of those!)

First things first: resin storage and handling. These materials are sensitive to light and temperature, so proper storage is crucial. I keep my resins in a cool, dark cabinet, and always give them a good shake before use. It’s a simple step, but it ensures consistent results print after print.

When it comes to slicing your model, orientation is everything.

I’ve found that angling your prints at about 45 degrees often provides the best balance between detail preservation and support structure efficiency. It takes some experimentation, but once you find that sweet spot, your prints will thank you for it.

The Printing Process

Once your print is underway, it’s tempting to just walk away and hope for the best. But keeping an eye on those first few layers can save you hours of wasted time and resin.

I always stick around to make sure the initial layers adhere properly to the build plate. If something looks off, a quick intervention can often save the print.

One aspect of resin printing that took me a while to master was exposure times. Every resin has its own optimal exposure time, and it can vary based on your printer’s light source and the geometry of your model.

I highly recommend running exposure tests whenever you switch to a new resin or printer. It might seem tedious, but it’s the best way to dial in those perfect settings.

Post-Processing Innovations

Post-processing used to be the bane of my existence. Hours of cleaning and curing, often with mixed results. But recent innovations have made this step much more manageable.

Automated washing stations have been a game-changer for me. They clean prints more thoroughly and consistently than I ever could by hand.

Curing has also seen significant improvements. UV curing chambers with rotating platforms ensure even curing from all angles. Some even have built-in heat control, which can help reduce warping in larger prints. It’s the kind of technology that makes you wonder how we ever managed without it.
