Drying temperatures and re-absorption time corrected
· How to Dry Filament (and When You Actually Need To)
The drying table gave PLA 45 to 55 °C and PETG 60 to 65 °C for 4 to 6 hours without a source. It now uses manufacturer figures: Prusa lists 45 °C for 6 hours for PLA and 55 °C for 6 hours for PETG, and Bambu Lab lists 50 °C and 60 to 65 °C for 8 hours. The article also said dried filament takes days to weeks to re-absorb moisture. Bambu Lab says that at about 55% humidity it can pick up enough to affect print quality within 2 to 12 hours, and the article now says that.
Unsourced retraction and travel-speed ranges removed
· 3D Printer Stringing: Causes and How to Fix It
The article gave retraction distances, retraction speeds and a 150 mm/s travel speed with no source. Those figures were removed and replaced with values from Prusa, Bambu Lab and OrcaSlicer documentation.
Temperature and heat-resistance ranges replaced with sourced figures
· Types of 3D Printer Filament: PLA, PETG, ABS, TPU and More
Several temperature and heat-resistance ranges had no source. They were replaced with Prusa's figures (for example, PLA softens above about 60 °C, PETG is used below 80 °C, and ASA is rated up to 93 °C). An unsourced answer about the strongest filament was removed.
Layer-height rule of thumb corrected
· 3D Printer Nozzle Sizes: 0.2, 0.4, 0.6 and 0.8 mm Compared
The article said layer height should be 25 to 75% of the nozzle diameter. Prusa's guidance is to stay below about 80% of the nozzle diameter, and the article now says that. The hardened-steel temperature advice was also aligned with Prusa's figure of about 5 °C.
Unsourced first-layer figures removed
· 3D Printer First Layer Problems: Causes and Fixes
Z-adjustment step sizes, a first-layer speed range and bed temperatures were given without a source. They were replaced with Prusa's guidance (about 75% speed for the first three layers) and Bambu Lab's stated bed temperatures. A claim that a warm bed causes elephant's foot was removed because no source supported it.
Claims not found on Creality's pages removed
· Creality Ender-3 V3 SE: Cheap Auto-Leveling Starter Printer
A claim that the printer prints within 20 minutes of unboxing and a 235 mm PEI plate accessory were removed because Creality's current product and support pages do not mention them.
Weight, availability and related-model claims corrected
· Creality K2 Plus: 350 mm Enclosed Printer for Large Parts
The printer weight was given as 33.5 kg; Creality's page says 35 kg. The page was described as out of stock when the store listed it as in stock. A line that Creality lists a K3, K2 Pro and K2 SE was removed because only the K2 Combo and K2 SE 4C appear in the store. The page now notes that the CFS multicolor system is not compatible with flexible TPU.
Prices replaced with US store prices
· Prusa Core One: Enclosed CoreXY, Kit or Assembled
The kit price (from $925) and assembled price ($1,202.78) were not US store prices. With US shipping selected, Prusa lists the CORE One+ (Gen 2) kit at $999 and the assembled printer at $1,299, and the article now shows those.
Firmware wording corrected
· Elegoo Centauri Carbon: Enclosed CoreXY, No Cloud Needed
The article referred to Elegoo OS firmware. Tom's Hardware's review describes an Elegoo fork of Klipper, and the wording was changed to match.
Pre-assembly claim removed
· Anycubic Kobra S1: Budget Enclosed Multicolor CoreXY
The article said the printer arrives 95 percent pre-assembled. Anycubic's current product page does not say this, so the claim was removed.
Neptune 3 Pro price corrected
· Best Budget 3D Printers Under $350: 6 Picks Compared
The Elegoo Neptune 3 Pro was listed at $179, which was a sale-banner price. Elegoo's US store lists the regular price as $259.99, and the article now uses that.
Price ratio corrected
· Cheap vs Premium Filament: What Actually Differs
The article said premium filament costs about twice as much as cheap filament, which mixed US and UK prices. The ratio is about 1.4 to 1 using US dollar prices and about 2.1 to 1 using UK pound prices. A citation labeled as the UK store also linked to the US store and was fixed.
ABS-like resin price range corrected
· Types of 3D Printer Resin: Standard, Tough and More
The article gave ABS-like resin as $17.99 to $19.99 for the core versions. That range wrongly included the V2.0 resin, which is $26.99. The article now gives the V3.0 versions at $17.99 to $19.99 and lists the older V2.0 separately at $26.99.
Unverified dryer temperature range removed
· Best Filament Dryers: 4 Picks and How to Choose One
A temperature range of 45 to 70 °C for a Creality dryer could not be confirmed on Creality's page and was removed.
Unverified specification rows removed
· Bambu Lab P1S vs P2S: Is the Upgrade Worth It?
Several specification rows and a supporting citation could not be verified and were removed. The P2S maximum speed (600 mm/s) and weight (14.9 kg) now come from Bambu Lab's spec sheet.
Creality K2 and K2 Combo prices separated
· How Much Does a 3D Printer Cost? Prices by Budget
The table showed one Creality K2 price with a note that the page also listed a second price. These were two different products: the K2 at £339 and the K2 Combo at £449.
