Learn. Test. Create. Sell.
Master UV laser engraving from your first glass test to advanced crystal production.
The RTC Ultimate UV Laser Glass & Crystal Engraving Guide is a comprehensive digital reference for beginners and experienced engravers working with UV lasers, with a strong focus on glass, crystal and 3D crystal engraving.
Built around the xTool F2 Ultra UV workflow, this guide takes you from understanding UV laser technology through material testing, artwork preparation, engraving, troubleshooting, production workflows and profitable product ideas.
Learn UV fundamentals, how UV compares with Fiber, CO₂ and Diode lasers, and the principles behind cold marking.
Glass types, artwork preparation, starter settings, test grids, troubleshooting and production workflows.
Crystal types, subsurface engraving, focus techniques, starter settings, common mistakes and quality optimisation.
Voxels, point clouds, layer spacing, depth creation and workflow optimisation.
Starter settings, material comparisons and test grids to help develop reliable settings for your own machine and materials.
Diagnose chipping, cracking, clouding, poor detail, focus issues, crystal fractures and inconsistent materials.
Move beyond experimentation and learn how to approach repeatable production.
Explore personalised drinkware, awards, memorial products, corporate gifts, crystal products and personalised gifts.
UV laser results can vary depending on the machine, laser source, lens configuration, material composition, supplier, focus and environment.
The settings are starting points and educational references. Run your own test grids, optimise results and build your own proven settings library before production.
Learn → Start → Test → Optimise → Record → Repeat
The goal isn't simply to give you a setting. It's to teach you how to produce repeatable results.

About Rellaw Trading Co
We are a small, family-owned South African business built around a passion for precision, creativity and practical solutions.
Our journey began with a love of laser engraving and precision craftsmanship, creating personalised products and exploring what modern laser technology can achieve across different materials and applications.
As our experience grew, so did our interest in helping other laser users get better results from their machines.
Today, Rellaw Trading Co focuses on laser engraving education, digital tools, workflow systems and practical resources designed for beginners, hobbyists, makers, side-hustles and small laser businesses.
Our digital guides and systems are built around a simple philosophy:
Learn → Test → Adjust → Record → Repeat
Rather than chasing one-size-fits-all settings, we believe laser users should understand their machines, test their materials and develop workflows that produce repeatable results.
Our resources cover areas including laser settings, calibration, engraving workflows, troubleshooting, coin engraving, UV glass and crystal engraving, and laser business opportunities.
We believe good results come from a combination of knowledge, testing and experience.
As a family business, we take pride in providing practical resources, honest information and helpful customer service. Every product we develop is created with the aim of making laser engraving easier to understand, easier to test and easier to turn into something you're proud of.
