UV aging of 3D-printing resin tested by Eindhoven University

Researchers and students at the University of Applied Science investigated the UV aging and UV stability of 3D-printed Liqcreate resins. The aim of this research was determining the effect of UV light on Liqcreate resins in the long-term. The analysed resins in this research were the Tough-X, Flexible-X and Strong-X resins. The resins were aged [...]

How to get a clear surface finish on 3D-printed parts?

Clear and transparent 3D prints are ideal for creating clear prototype parts, showing internal cavities and details. Applications like LED housings, prototyping lens parts and microfluidic devices are a few examples of application 3D-printed with clear resin. Resin 3D-printing is one of the only 3D-printing technologies that can create high resolution transparent plastic parts. One of [...]

Linear shrinkage of 3D-printing resins

In the field of resin 3D-printing there are two mainstream resin technologies. One based on acrylates and the other one based on epoxides. In large scale SLA 3D-printers like from UnionTech, 3DSystems, Raplas, RPS, EnvisionTEC and others, epoxy resins are the standard. These materials cure by a mechanism of ring-opening-polymerization which limits the shrinkage which [...]

Solid density of 3D-printed resin parts after post-processing

The liquid density of 3D-printing resins is provided in all technical data sheets. From time to time we received questions regarding the density of solid, 3D-printed parts. In this article you can find the solid density of Liqcreate resins. Density and of different objects make them behave different in a liquid, source Anton Paar. What [...]

Water washable resins: the advantages and disadvantages

Over the past years a wide range of water-washable resins were introduced to the market to make resin printing more consumer friendly. But what are the advantages of these water-washable resins and how do they compare to other resins? Post-processing of 3D-printed resin parts One of the biggest disadvantages of resin 3D-printing is the post-processing. [...]

Low odor & odourless 3D-printing resin

One of the downsides many people experience with resin 3D-printing, is the bad odor of some of the resins and cleaning agents. In order to avoid this smell in their working area, many people get creative and build their own fume hood, just like the picture below. The question is, can this be avoided? Source: [...]

Best practice for 3D-printing with Composite resins

Liqcreate Composite-X is one of the stiffest and strongest resins available in the market. With a flexural modulus over 9000 MPa and a flexural strength of 150 – 170 MPa it is superior to almost all photopolymer resins currently available. Liqcreate Composite-X is fairly easy to use for experience users on all open SLA, DLP [...]

How to work with Liqcreate Hazard Glow, glow in the dark resin?

Liqcreate Hazard Glow is the first ever glow in the dark resin for SLA and DLP technologies in a range of 385 – 405nm. This material is optimized in having the highest possible glow-effect while remaining processable in DLP, MSLA and SLA 3D-printers. Parts 3D-printed with Liqcreate Hazard Glow can be activated with almost every [...]

How to process flexible 3D-printing resin?

Learn about Flexible and elastic 3D-printing resins

Whilst the 3D-printing market grows rapidly, the demand for better 3D-printing materials grows with it. This leads to the development of a wide variety of materials. All new types of resins are finding their way into the market for specific applications. Earlier we wrote an article about the Strongest and Toughest materials available. One of [...]
