Fast printing with a PDMS resin tank

One of the 3D printing community's strong interests is fast printing without waiting hours to print 1 inch tall object. A print speed of 1 inch/hr is considered as standard for DLP based printers. The most time consuming step besides actual exposure is separating the cured layer from container bottom and refilling the gap with liquid resin. To do this, the build platform needs to move vertically or horizontally, which takes 2-7 seconds per each layer depending on mechanism, settings, build area, and resin.  A key is how to make an inhibition layer. CLIP technology from Carbon3D offers a true continuous printing,...

Printing single pixel wide micro-patterns with Mono1

One of potential applications using high resolution 3D resin printers like Mono1 is affordable alternative to patterning micro-structures. Usually micropatterns are fabricated using equipment for manufacturing semi-conductor devices. Of course they are expensive and hard to access or process. I've got several requests how well Mono1 can do this.  Here's a brief test and you can get a rough estimate about Mono1's capability in the area of microfabrication. Let's check out test results first.  I printed narrow and long extrusions using B9C cherry resin. The designed widths are 25, 50, 75, 100, 150, and 200 microns and those widths were converted...

High resolution printing with Mono1

High resolution printing with Mono1

Here are some recent test about high resolution printing with Mono1. I usually use Fun To Do resins (Deep Black, Industrial Blend, and Snow White) for high resolution printing since they offer a fast curing time and cheap price tags, however they have a limitation when it comes to extremely high resolution printings. I've tested FTD Deep black resin using Mono1 and Optoma HD37 to print 23 micron xy resolution and 50 micron layer thickness. It generally shows nice details, but light bleeding can't be controlled at minimum exposure times. Then I decided to try a wax resin from B9Creators, Cherry resin....
