Summary of "3D Printing Was AWFUL 5 Years Ago"

High-level summary

The video’s creator (Adam) reviews how consumer 3D printing has changed in roughly five years by revisiting an Ender 3 V2. He demonstrates the practical pain points of older budget machines and explains the industry shifts that made modern printers faster, more reliable, and more user-friendly.

Ender 3 V2 — hands-on demo and problems

Stock features

Upgraded screen, integrated PSU/motherboard, small toolbox.
Bowden extruder (motor mounted away from the hotend).

Key drawbacks of the stock configuration

Bowden setup: lighter print head but poor for flexible filaments due to long PTFE tube/back‑feeding, causing slop and extrusion issues.
No auto bed leveling.
Single Z lead screw: susceptible to gantry tilt/slump if the eccentric nut or fasteners loosen.
PTFE tube routed close to the hot zone (risk of softening/degradation).

Common user fixes / popular mods

BLTouch‑style bed leveling probe to replace manual spring/screw leveling.
Dual Z lead screw upgrade for gantry stability and alignment.
All‑metal hotend (e.g., Microswiss) to avoid PTFE overheating and to enable PETG/higher‑temperature materials.
Direct‑drive extruder swaps to reliably print flexible filaments.

Practical workflows and older pain points demonstrated

Manual mesh bed leveling and saving mesh to EEPROM.
Cutting filament at a ~45° angle to ease insertion.
SD card formatting issues and odd file/compatibility failures.
Glass bed adhesion problems (e.g., PETG printing without glue).

Real‑world impact

Older budget printers were much slower: example given of prints that took ~10 hours on an unmodified Ender vs ~2 hours on modern fast machines.
As a result, some users relied on having multiple printers in parallel rather than investing in speed upgrades.

Demo note

The hands‑on attempt to print a simple “nacho tester” on the Ender 3 V2 illustrates common setup friction; the print was not completed.

Industry turning point — Bamboo Lab X1 Carbon

What the X1 Carbon did

Packaged several features into a consumer product, making them accessible and reliable out of the box rather than as piecemeal mods:
- Automatic bed leveling
- Input shaping and vibration compensation
- Micro LiDAR / toolhead scanning to auto‑adjust settings
- Filament runout sensing, accelerometer‑based tuning, filament cutter
- Consistent part cooling and an enclosed heated chamber (256 mm cube)
- Multi‑material/multi‑color “box” accessory

Effect on the market

Raised mainstream expectations: features that were previously add‑ons became expected out‑of‑the‑box capabilities.
Other manufacturers quickly adopted similar conveniences (multi‑material boxes, purge wipers, nozzle scrubbers, etc).
Bamboo Lab’s success attributed more to packaging and user experience than to inventing each individual feature.
Pricing (~US$1,200–1,500 for combos) was framed as fair value for a highly integrated experience.

Current and near‑future trends

Tool changers

Emerging as the next major wave in consumer 3D printing.
Examples mentioned: Snapmaker U1, Bamboo H2C, Bond Index (upcoming), and Vontek (referenced by commenters).
Advantages:
- Enable multi‑material/multi‑color printing without the same purge waste penalties of single‑nozzle multi‑material boxes.
- Better support for multi‑tool workflows (e.g., swapping extruders, mill, or other end‑tools).

Market prediction

Within about a year, more brands are expected to offer or announce tool changers, shifting momentum away from single‑nozzle multi‑color solutions.

Overall trajectory

Printers are becoming faster, more automated, and more integrated across hardware, firmware, and slicer software — making them more consumer‑friendly.

Guides, reviews, and tutorials referenced

Channel’s early mod videos: step‑by‑step guides for adding bed‑leveling probes, dual Z installs, all‑metal hotend conversions, and direct‑drive swaps (creator notes these early videos are “bad” but exist).
Hands‑on demo: the Ender 3 V2 “nacho tester” print used to show typical setup friction.
Practical tips repeated in the video: manual mesh leveling and saving to EEPROM, filament insertion technique, SD card troubleshooting, and PETG bed prep.

Practical cautions and technical notes

PTFE liners/heat limit: PTFE begins to degrade near ~240°C — use all‑metal hotends for PETG or higher temperatures.
Spring‑based beds: stock springs on Ender‑style beds often lose level quickly; stiffer springs or auto‑level probes help maintain consistency.
Bowden systems are problematic for printing flexible filaments; direct‑drive is preferable.
SD card and file compatibility issues were common on older machines; saving settings and file formatting could be unreliable.
