Tired of Failed Prints and Wasting Time?
You model something in Blender.

It looks great.

You send it to your slicer… and something goes wrong.
- Parts are too small
- Holes appear out of nowhere
- Pieces don’t print right
- The slicer throws errors
- Prints fail halfwayÂ
You try to fix it.
But Blender (and your slicer) doesn’t tell you what the issue is.
đź‘Ž Common Problems That Ruin Prints
These are the real reasons your prints fail:
Wrong scale – your model is the wrong size because Blender uses meters and your printer uses millimeters
Huge polygon count – dense geometry crashes your slicer or takes forever to slice
Holes or missing faces – your mesh isn’t “watertight,” so the slicer gets confused
Mesh is too tall / too thin – your print fails halfway
Unapplied modifiers – Mirror, Solidify, and Boolean don’t export unless applied
Supports are breaking off the slicer bed – your printer just stops out of nowhere
Inverted normals – your model looks fine, but faces are pointing the wrong way
Support breaking in half during print – AGAIN, your printer fails
Paper-thin walls – looks okay in Blender, but walls break after printing
Printing takes hours and hours (WAY too long) – you’re wasting time and money
Overhangs – cool shapes, but gravity says no
Bad export settings – STL looks nothing like your Blender file
Gaps between your mesh and filament droops all over the model
Constant back-and-forth – fix, export, slice, fail… repeat
Supports difficult to break after printing – you break it, then the entire model breaks with it. Money wasted. Gotta re-print again.
Sound familiar?
Well, this course has step-by-step solutions and visual explanations for all of these issues.
The Fix: A Step by Step 4-Hour Course That Solves It All
This course shows you how to fix every problem above using Blender.
No fluff. No guesswork.

Just clear answers and walkthroughs.
In less than 4 hours, you'll learn:
How to clean up the mesh in Blender before export
How to use Blender for 3D printing (tools & workflow)
How to check for holes, bad normals, and broken geometry
How to make sure everything exports the way you see it
How to prep any model to actually print – you need a clean and manifold mesh
How to spot slicing issues before you waste time and filament
How to handle overhangs, thin walls, and tolerances the right way
We even show the full workflow using one of our mech models from the Accelerator course.
None of this is theory – we show you how to do everything step-by-step inside the course.
Who This Is For
Â
This course is for you if:
- You know the basics of Blender

If you’re serious about getting clean, reliable 3D prints from Blender…
This is the shortcut.
4 hours.
One course.
Every major Blender-to-printer issue solved.
⚠️ “WAIT! But I Don’t Own A Printer…”
Guess what?
You don’t even need to own a printer.
A friend of mine runs a freelancing business where he simply prepares models for 3D printing.
He just sends over the file to whatever client he is working with.
He also re-sells STL files for people who do own printers… but don’t want to model.
So if you still want to work within the 3D printing space without owning a printer, you can.
(People are making $$$ doing this as freelance work as well)

But Hold Tight… I Know What You’re Thinking
“I can learn this for free on YouTube!”
Sure - if you’ve got weeks to waste piecing together outdated, half-baked tutorials. This course gives you everything you need - clearly explained, in under 4 hours. You're not paying for random info. You're paying to save time and fix your prints now.
“$397 for this course is a bit pricey…”
So is wasted filament, failed prints, missed deadlines and lost client opportunities. One bad print can cost way more than this course. Lack of info means you can’t make money using this skill. This is a small investment to stop losing money before it happens.
“I don’t own a printer and have never printed before.”
No problem. Many of our students don’t print themselves - they sell printable models, or prep files for clients who do. This course shows you how to make sure your Blender files are actually printable.
“This won’t work with my printer or slicer.”
We use a specific slicer and printer for demonstration, but the principles - clean geometry, scale, wall thickness, and correct normals - are universal and work with any slicer and any printer.
“But won't AI just automate this too?”
No. Unlike retopology, UVs, or texture nodes, 3D printing is physical and practical. Models still need to be manually prepared for slicing. Clients still need real-world solutions. This is one skill that won’t be easily replaced - in fact, it’s only becoming more in demand.

Return on Investment: How Fast This Course Pays for Itself
| Scenario | Without Course 💀 | With Course 🚀 |
|---|---|---|
| Print fails due to wrong scale | $10 wasted filament + 3 hours lost = $80 | Fixed in minutes — $0 lost |
| Print fails halfway due to supports breaking off | $7 filament + 6 hours print time = $130+ | Pre-checked in Blender — $0 lost |
| Client job: model fails, needs rework | Missed deadline, lost gig = $200+ | Clean export, delivered on time — $200 earned |
| Selling STL: customer says file is broken | Refund + 1-star rating = reputation loss | Print-ready file = repeat buyer |
| Time spent learning on YouTube | 10–20 hours wasted and your prints still fail | Full workflow learned in 4 hrs |
