Common Resin Printing Mistakes with Elegoo (and How to Avoid Them) 🧪🚫

Resin printing is amazing… until something goes wrong.

Layers that won't stick, prints glued to the FEP, miniatures snapping when you remove supports, details that disappear, or prints that simply fail completely.

If you're using Elegoo resin — one of the most popular on the market — you should know that most failures aren't caused by the resin itself, but by small misconfigured settings.

In this guide we'll walk through the most common Elegoo resin printing failures and, more importantly, how to fix them step by step.

1️⃣ Print won't stick to the build plate (and stays stuck to the FEP)

The classic failure.

You start a print, everything seems fine… and when you check, the part is stuck to the bottom of the vat.

🔍 Why does this happen?

• Bottom exposure time set too low.

• Build plate not levelled properly.

• Worn or damaged FEP film.

• Ambient temperature too low.

✅ How to fix it

• Increase the bottom layer exposure time.

• Re-level your build plate.

• Check that the FEP isn't scratched or loose.

• Try printing at 20–25 °C.

This issue can occur with Standard, ABS-Like, and Water Washable resins alike.

2️⃣ Layers delaminating mid-print

You've made it past the first layers, but suddenly the print splits or stops forming correctly.

🔍 Common Causes

• Poorly placed supports.

• Wrong model orientation.

• Insufficient exposure time.

• Resin that's too cold.

✅ Fix

• Add more supports in critical areas.

• Tilt the model between 30° and 45°.

• Fine-tune your exposure time settings.

• Make sure the resin is properly mixed before printing.

This is especially common when printing highly detailed miniatures with 8K resins.

3️⃣ The print comes out brittle and breaks when you touch it

Many users blame the brand, but the real issue is usually the type of resin they chose.

🔍 What's going on?

If you're using a Standard resin for functional parts, the print will be rigid and brittle.

✅ Fix

If you need durability, switch to an ABS-Like V3.0.

It's more flexible, handles impact better, and holds up under stress.

4️⃣ The surface is still tacky after curing

This is a more common issue than you'd think.

🔍 Reasons

• Not washed long enough.

• Dirty alcohol.

• Insufficient curing time.

• Resin pooling in fine details.

✅ How to avoid it

• Change your alcohol regularly.

• Wash for at least 2–3 minutes.

• Make sure the print is completely dry before curing.

• Cure for the recommended time based on the size of your print.

With Water Washable resins, this can also happen if the print isn't rinsed thoroughly enough.

5️⃣ Visible layer lines or banding

If you're seeing heavy layer lines or banding, the resin isn't always to blame.

🔍 Possible causes

• Dirty or poorly lubricated Z-axis.

• Layer height set too high.

• Vibrations from the printer.

✅ How to fix it

• Lubricate the Z-axis.

• Reduce layer height to 0.03–0.05 mm.

• Check that your printer is stable and not wobbling.

Elegoo 8K resins help minimise this effect thanks to their higher precision formula.

6️⃣ Bubbles or microbubbles in your print

This is a very common issue when the resin bottle hasn't been shaken properly.

🔍 Why it happens

• Resin not properly mixed.

• Low ambient temperature.

• Over-shaking without letting it settle.

✅ How to fix it

• Shake the bottle thoroughly before use.

• Let it sit for a few minutes before printing.

• Filter the resin when pouring it back into the bottle.

7️⃣ Warping or deformed prints

If your print is warping or bending:

🔍 Causes

• Insufficient supports.

• Unstable temperature.

• Uneven post-curing.

✅ How to Avoid It

• Reinforce supports on flat areas.

• Keep temperature consistent.

• Cure all sides evenly.

ABS-Like resin tends to warp less than Standard resin in functional parts.

8️⃣ Strong Smell During Printing

Even though Elegoo has improved formulations, resin is still a chemical material.

🔍 Causes

• Poor ventilation.

• Lid left open.

• Resin vat left exposed for too long.

✅ Solution

• Print in a well-ventilated space.

• Use an activated carbon filter.

• Consider the Water Washable version — it typically has less odour.

9️⃣ Repeated Failures Even When Settings Seem Correct

If everything looks right but prints keep failing:

Quick Checklist:

• Have you updated your slicer?

• Is the LCD screen clean?

• Is the FEP film taut?

• Is the resin still in date?

• Have you tried a different print profile?

Sometimes a small tweak to your exposure time is all it takes.

Is It a Resin Problem or a Settings Problem?

Here's the uncomfortable truth:

In 90% of cases, the issue isn't the resin — it's down to:

• Poor calibration.

• Wrong orientation.

• Incorrect parameters.

• Cold environment.

Elegoo is one of the most consistent brands on the market. If you're using the right resin for your project and dialling in the correct settings, the results should be excellent.

Conclusion: print smarter, not more often 🚀

Resin printing has a learning curve, but mastering these common mistakes will put you a step ahead of the rest.

Remember:

• Miniatures → Standard or 8K.

• Functional parts → ABS-Like.

• Home use → Water Washable.

And if something goes wrong, check your settings before blaming the brand.

At Mr Resin, we work with Elegoo resins every day — and we know that with the right settings, the results are truly spectacular.
