The 3D Printing by Kevin knowledge hub
Find the right 3D printing guide for the job in front of you
You should not have to search through dozens of posts to answer one practical question. Use this directory to learn the workflow, choose equipment, design a part, select material, improve quality, diagnose a failure, or start a custom project.
Not sure where to begin? New printer owners should start with the absolute beginner guide. If you need one finished part rather than a new hobby, go directly to custom design and project intake.

Choose your path
I am completely new
Understand models, slicers, materials, first layers, safety, and the first successful print.
I need the right printer
Match build size, material support, reliability, service, and total ownership cost to real projects.
I need a custom fit
Measure the interfaces, define requirements, build the CAD model, and test the riskiest feature.
My prints need work
Name the visible symptom, return to a known baseline, and change one relevant variable.
I have a broken part
Decide whether the part is printable, safe to reproduce, measurable, and worth redesigning.
I need the result, not the hobby
Send a sketch, file, photo, measurements, or sample for a custom project evaluation.
Start here: 3D printing fundamentals
3D Printing for Absolute Beginners
A step-by-step FDM workflow covering essential equipment, a simple first model, slicer preview, build-plate preparation, first-layer checks, troubleshooting, and safety.
Can a 3D Printer Make Your Ideas Real?
A realistic look at useful home projects, total costs, safety limits, learning value, and whether buying a machine makes sense for your goal.
P.R.I.N.T. It: Practical 3D Printing for Beginners
Kevin’s structured beginner ebook for turning a problem into requirements, interfaces, material and method choices, then a controlled test.
Credible 3D Printing Resources
A verified directory of official documentation, slicer help, CAD manuals, calibration guidance, model libraries, and correctly attributed creators.
Choose a printer and supporting equipment
Guide to Choosing the Right 3D Printer
Start with what you plan to make, then match material capability, build volume, enclosure, maintenance, workflow, and support—not just headline speed.
Creality Space Pi Filament Dryer
A fact-checked specification guide explaining when a dryer can help, what the Space Pi supports, its 70°C ceiling, and why drying is not the same as storage.
Directory policy: Printer models, prices, bundles, and availability change quickly. This hub links to maintained selection criteria instead of naming a permanent “best” machine.
Design, measurement, and prototyping
How to Measure a Part for 3D Printing
Learn how to establish datums, capture important dimensions, measure mating features, account for clearance, and record what matters before opening CAD.
From Idea to Finished Part
See how a sketch, broken sample, scan, CAD model, material decision, prototype, and test fit become a usable custom part.
Acquiring the Skills to Design 3D Objects
An introduction to developing the design habits and software skills needed to move beyond downloaded models.
The P.R.I.N.T. Method™
Define the Problem, Requirements, Interfaces, Next-Best Materials & Methods, then Test & Tune. Use it before committing to a full print.
Materials, filament condition, and storage
Professional-Quality PLA Prints
Improve PLA results through a controlled baseline, appropriate temperatures, cooling, first-layer preparation, orientation, and symptom-based tuning.
3D Printing With PETG
Understand PETG’s strength, temperature resistance, adhesion behavior, stringing tendencies, and where it can be a better fit than PLA.
3D Printing With ABS
Learn why enclosure temperature, ventilation, warping control, material handling, and part requirements matter with ABS.
Drying Is Not Storage
Recognize credible moisture symptoms, run a controlled before-and-after test, and combine heated drying with sealed storage and maintained desiccant.
Print quality, calibration, and troubleshooting
Fix Common 3D Printing Problems Quickly
Match visible problems to a short list of causes, return to a known baseline, and change one relevant setting or mechanical condition per test.
Stop PLA, PETG, and ABS Warping
Separate first-layer problems, plate contamination, thermal contraction, cooling, enclosure conditions, and geometry before adding more adhesive.
Verified Support and Tuning Sources
Find official printer documentation, OrcaSlicer and Cura help, CAD manuals, Ellis’ tuning guide, and experienced educators.
Replacement parts and practical repairs
Broken Brackets and Clips
Evaluate load, environment, interfaces, failure mode, material, and consequence before reproducing or redesigning a broken plastic part.
Discontinued Plastic Parts
See when reverse engineering can extend a product’s useful life—and when another manufacturing method is safer or more economical.
Plastic Mounts and Holders
Plan a mount around real loads, access, hardware, mating geometry, clearances, and the direction of the printed layers.
Tool Holders and Organizers
Turn awkward storage and workflow problems into measured, purpose-built organizers and holders.
Official documentation and independent resources
This directory organizes Kevin’s own guides. When you need model-specific firmware, maintenance, slicer, calibration, or CAD instructions, use the separate credible 3D printing resources directory. It explains why official documentation should usually come before videos, forum guesses, or copied settings.
Source rule: Match every recommendation to your exact printer, nozzle, material, slicer, and software version. Check the date, look for a repeatable test, and keep a known-good baseline.
Custom 3D design, prototyping, and printing
You do not need to buy a printer to get one useful part made. Kevin can evaluate projects that begin with a sketch, photograph, broken sample, measurement set, STL, STEP, OBJ, or an early concept.
| What you have | What to send |
|---|---|
| A broken or discontinued part | Overall photos, close-ups, a ruler for scale, mating object, failure location, and what the part must withstand |
| A sketch or idea | Purpose, key dimensions, mounting method, environment, quantity, deadline, and what success looks like |
| A printable file | STL, STEP, or OBJ plus size, material needs, quantity, finish, fit requirements, and intended use |
| A confidential concept | A non-sensitive summary first; use the documented NDA workflow before sharing protected details |
Use the P.R.I.N.T. Method™ to navigate any project
- P — Problem
- Start with the real need, then choose the appropriate directory section.
- R — Requirements
- Capture dimensions, loads, heat, environment, appearance, quantity, budget, and deadline.
- I — Interfaces
- Identify mating surfaces, fasteners, clearances, and measurement references.
- N — Next-Best Materials & Methods
- Use the material, equipment, and source guidance that match the requirements.
- T — Test & Tune
- Prototype the riskiest feature, measure it, and change one variable at a time.
Directory questions
Where should a complete beginner start?
Begin with 3D Printing for Absolute Beginners. It explains the full FDM workflow without requiring you to understand every setting first.
Where can I find help for one failed print?
Use the common-problems guide and identify the visible symptom. Then compare the advice with documentation for your exact printer and slicer.
Where should I compare current 3D printers?
Use the printer selection guide. This directory intentionally avoids a permanent “best printer” claim because models, prices, firmware, and support change.
Can Kevin create a model if I do not have an STL?
Yes, some projects can begin with a sample part, sketch, photograph, measurements, or concept. Use the project intake form so the design and printing requirements can be evaluated.
