When setting up a resin 3D printer, one of the most common dilemmas makers face is choosing between standard photopolymer resin and ABS-like (or tough) resin.
While both print using ultraviolet light (SLA, MSLA, or LCD technology) and capture incredible microscopic details, they behave entirely differently once cured.
Choosing the wrong one for your project can lead to shattered models under stress or wasted money on expensive engineering formulas you didn't need. Here is a head-to-head comparison to help you decide which bottle to put in your shopping cart.
Material Strength and Brittleness
The single biggest difference between these two resins is how they react to physical force.
Standard Resin:
Highly rigid, but extremely brittle. If you drop a standard resin figurine or bump a thin protruding part (like a sword, staff, or wing), it will snap cleanly or shatter like glass.
ABS-Like Resin:
Engineered to mimic traditional acrylonitrile butadiene styrene (ABS) plastic. It offers higher impact resistance and flexural strength, meaning it can absorb shocks and bend slightly under pressure rather than breaking instantly.
Ideal Applications
Matching the material's physical properties to your project's end use is crucial:
Best Uses for Standard Resin:
Tabletop gaming miniatures, display statues, highly detailed artistic sculptures, and decorative desk items that will sit safely on a shelf.
Best Uses for ABS-Like Resin:
Functional mechanical parts, snap-fit enclosures, hinges, tools, brackets, and any prototype or toy that requires durability and daily handling.
Cost and Availability
Standard Resin:
The most budget-friendly option on the market. Because of its massive production volume, it is widely available in dozens of vibrant, translucent, and opaque colors.
ABS-Like Resin:
Generally carries a modest price premium (often 15% to 30% more expensive than standard formulas) and tends to have a slightly more limited color palette, usually focusing on functional grays, blacks, and whites.
Printing Process and Post-Processing
From a machine's perspective, both resins print similarly, but you may need to tweak your settings:
Viscosity and Exposure:
ABS-like resins are often slightly thicker (higher viscosity) than standard resins. Because of this, you may need to bump up your bottom exposure times slightly or warm up the resin bottle before a print to ensure reliable bed adhesion.
Cleanup and Curing:
Both types typically require a post-print wash in isopropyl alcohol (IPA) and a thorough UV post-cure. However, cured ABS-like prints are often easier to sand, drill, and tap without chipping.
Quick Decision Guide
Go with Standard Resin if:
You are printing miniatures or display models where ultimate visual detail, vibrant color selection, and low cost are your top priorities.
Go with ABS-Like Resin if:
Your prints need to endure mechanical stress, drops, assembly, or functional real-world use where durability matters more than a flashy color.
Modern hybrid and rubber-toughened ABS-like resins now feature elongation-at-break percentages exceeding 30%, bridging the gap between rigid plastics and semi-flexible elastomers for advanced engineering prototyping.
Additionally, many manufacturers are now introducing low-odor bio-blended ABS-like formulations that eliminate the strong chemical fumes traditionally associated with tough engineering resins, making them much more comfortable to use in home workshops and shared maker spaces.
