3D printing has two shopping lists that rarely overlap: the gear that turns physical objects into files (scanners), and the material that turns files into objects (filament). The two brands we have reviewed in this category cover one side each. Revopoint sells 3D scanners from a $239 refurbished unit up to $9,800 robotic systems. Eryone sells budget filament, a filament dryer, and parts for its own Thinker X400 printer. Neither sells what the other sells, so this guide ranks them by how well each does its own job and tells you which to buy for which task. ## Quick verdict
| Brand | Our take | What it sells | Price range we saw | Returns and warranty | Best for |
|---|---|---|---|---|---|
| Revopoint | Best overall, clearest policies | Handheld, wireless, and robotic 3D scanners plus software | $239 to $9,800 | 30-day refund or exchange, 2-year scanner warranty | Scanning parts for reprinting, CAD, and inspection |
| Eryone | Good value, thin policy pages | PLA, PETG, TPU, silk and matte filament, dryer, Thinker X400 parts | About $11 to $90 per spool | No readable terms when we checked | Cheap filament in bulk and specialty finishes |
Best overall: Revopoint. It is stronger on every policy measure we track, publishes a clear 2-year scanner warranty, and has an upgrade path that runs from hobby to factory floor. Best value: Eryone. Its per-kilo filament prices are among the lowest we have seen, but you are buying with less protection, because its shipping and return pages showed no readable terms. ## 1. Revopoint: best overall, and the pick for 3D scanning
Revopoint is a scanner specialist. Its global store lists about 74 products, 13 of them scanners, and the rest are calibration boards, turntables, cables, software, and official refurbished units. What puts it on top is the combination of price ladder and policy: scanners carry a 2-year warranty, accessories get 1 year, and you can return for a refund or exchange within 30 days as long as you keep every accessory and the original packaging. The lineup steps up by the size and precision of what you want to scan:
- Entry and 3D printing: INSPIRE 2 at $439 an infrared laser plus structured light scanner aimed at people scanning objects to reprint. - All-rounder: POP 4 at $713 which adds blue laser to infrared in one wireless unit. - Detailed small parts: MetroX at $699 and MetroY at $923 blue laser line scanners for mechanical parts and reverse engineering. - Inspection: MetroY Ultra from $1,519, aimed at quality control on small to medium workpieces. - Large objects: Trackit SR at $3,329 and Trackit at $3,486, which use an external optical tracker so you do not have to stick markers on the part. - Automation: Metrohub 09YU at $7,800 and 09TR at $9,800, robotic systems for repeat inspection. Two things to know before buying. First, the store we reviewed is the global one. US and Japan customers are sent to separate regional stores, so buy from the store that matches your shipping address. Second, 63 of 74 products showed a sale price and some compare-at prices are inflated (the MetroY lists a $7,639 compare-at against $923). Judge the current price on its own. Software is extra. Revo Design Personal ($225) converts scans to CAD, Revo Measure ($499 or $49 a month) handles GD&T inspection, and software is non-refundable. If you only want to scan a broken knob and reprint it, you may not need any of it. If you plan to model from scans, add it to your budget. A useful detail: Revopoint offers a $49 sample scan service. Send a real part, get the scan data back, and judge quality before you spend $1,500 or more. ## 2. Eryone: best value for filament
Eryone is a filament brand first. Every spool we looked at is 1.75mm with a stated plus or minus 0.03mm tolerance, and the prices are low: standard PLA and PETG at $19.99 per kilo, a 3kg PLA spool at $59.99 (about $20 per kilo), and "Bundle Sale" listings that drop PETG Lite to $10.99 and PLA Lite Matte to $12 to $13 per spool. The listings do not explain the bundle terms, so check the minimum quantity before you assume one spool gets that price. Where Eryone is most interesting is specialty finishes. The High-Speed Quadruple Silk PLA ($29.99) puts four colors on one spool, is rated for 30 to 500mm/s, and comes with published lab data (62.7 MPa X-Y tensile strength, 19.1 MPa X-Z). PLA Lite Matte hides layer lines and does not need a heated bed. TPU 85A ($36.99) is softer than the common 95A TPU, good for grips and bumpers but harder to feed through a long Bowden tube. The Snail Dryer Box M2 ($49.99) dries one spool up to 68mm wide and shows humidity on a built-in readout. What holds Eryone back is one real weakness: when we reviewed the store, its shipping policy, refund policy, and FAQ pages showed no readable terms, which makes policies and transparency its weakest areas. For a $13 spool the risk is small. For a Thinker X400 printer or a stack of spools, email support and get the return and warranty terms in writing first. ## How to choose between them
Since these brands do not compete, the real question is which problem you are solving. - You want to copy or modify a physical object. You need a scanner. Start with Revopoint's INSPIRE 2 for printing replicas, or the POP 4 if you want blue laser detail too. - You make functional parts and need precise dimensions. Look at MetroX or MetroY, and consider the $49 sample scan first. - You print every day and filament is your biggest cost. Eryone's 3kg PLA or the bundle listings are hard to beat on price. - You print display pieces. Eryone's silk multicolor and matte lines are made for vases, figures, and props. - You print in a humid room. Pair any PETG or TPU order with a dryer; Eryone's M2 is $49.99. ## What to check before you buy any scanner or filament
Scanners: match the scanner to object size, not to the headline feature. Small-part blue laser scanners struggle with car panels, and large-object tracking systems are overkill for figurines. Check whether the edition you are buying includes a turntable or tripod, since several Revopoint listings do not spell out edition contents. Budget for software only if you will model from scans. Filament: stick to 1.75mm unless your printer uses 2.85mm. PLA is easiest and best for display, PETG is tougher and handles more heat, TPU is for flexible parts. Silk PLA looks great but has weak layer strength, so do not use it for brackets. Carbon fiber blends wear brass nozzles quickly; use a hardened steel nozzle. Policies: a 30-day return window and a 2-year warranty matter a lot on a $700 scanner and very little on a $20 spool. Spend your caution where the money is. ## Bottom line
Revopoint is the brand to trust with a large purchase in this category: clear warranty, a real return window, and a scanner for every object size. Eryone is the brand to try when you want cheap or unusual filament and can accept unclear policies on small orders. Many makers will end up using both, scanning with one and printing with the other.
