Longer3D is one of those brands you meet at the moment a hobby turns into a purchase. You have decided you want to cut and engrave your own wood, slate or anodised aluminium, you have seen a machine at a price that looks too good against the big names, and the question is whether the saving is real or whether you pay for it later. This Longer3D review answers that with what can actually be verified: published prices, the warranty and returns terms in full, independent hands-on testing, and what the review scores do and do not prove.

What Longer3D Is and Who Should Use It

Longer3D began as a 3D printer brand — the name says so — and has since moved its centre of gravity to laser engraving. The company claims over a decade in the industry, more than one million active users across 120+ markets, and 56+ patents. Support runs through support@longer.net and a US phone line, +1 (888) 575-9099, with a 24/7 online specialist advertised. Shipping is free over USD 49 in the US and EU, and the official Longer3D store carries the full catalogue.

The current Longer3D catalogue splits three ways. Laser engravers are the core: the Ray5 family from USD 109.99, the B1 at USD 469.99 in 20W, 30W and 40W, the Nano series at USD 499.99, and the Nano Duo AI at USD 1,519.99. UV printing is the new bet, headed by the ePrint dual-head at USD 1,699.00. And 3D printing — the original business — is now the smallest part of the range.

That last point deserves more attention than the marketing gives it, and we come back to it below. Prices below were taken from the Longer3D collection pages and change often with promotions.

What Independent Testing Actually Found

We have not run a Longer3D machine ourselves, so rather than invent a test we looked at what independent reviewers reported. The most detailed recent hands-on we found is 3DWithUs’s testing of the Longer Nano Pro 12W, and it is useful precisely because it is mixed.

On the positive side, the reviewer described the machine as feeling high quality, with most parts made of aluminium and minimal plastic — not a given at this price. It cut 0.5 mm feather detail into 2 mm basswood, and handled slate coasters, ceramic tile, natural pebbles and anodised aluminium. Software support is open rather than locked: LightBurn, LaserGRBL and Laserburn all work, and a TF card ships with pre-configured settings.

The criticisms are just as concrete. The base work area is 100 × 100 mm, which is genuinely small until you buy the sliding extension table. There is no air assist, and the reviewer recorded scorching even on thin material as a result. The enclosure was not available at the time of testing, so fumes had to be vented manually through an extension hose. And setting up the extension table and rotary attachment took noticeably longer than the base machine.

None of that is disqualifying. It does mean the advertised price is rarely the price you end up paying, because air assist, an enclosure and a larger bed are the accessories most people want within a month.

The 3D Printer Problem Nobody Mentions

If you are searching for Longer3D because you want a 3D printer, check stock before you get attached to a model. At the time of writing the 3D printer collection lists eleven machines and only three are in stock: the LK10 and LK10 Plus at USD 299.99 and the LK5 Pro at USD 279.99. The other eight — including both resin printers, the Orange 30 and Orange 4K, and the LK4 line — are marked sold out.

Longer3D has not announced that it is leaving 3D printing, and we are not claiming it has. But a catalogue where three quarters of the models are unavailable, and where the newest launches are all lasers and UV printers, is a catalogue that tells you where the company’s attention is. For a machine you expect to source spare nozzles, belts and hotends for over several years, that is a fair thing to weigh.

Longer3D Lineup Compared

Against xTool, Creality Falcon and Atomstack, the structural difference is enclosure and safety design rather than raw wattage: most Longer3D machines ship open-frame, with enclosures sold separately or bundled on selected SKUs, where several rivals build the enclosure in. If you have children, pets or a shared room, budget for the enclosure from the start rather than treating it as an upgrade.

Pros and Cons

Pros

• Strong price-to-hardware ratio; independent testing found mostly aluminium construction
• Open software — LightBurn, LaserGRBL and Laserburn, not a proprietary walled garden
• Wide ladder of models from USD 109.99 to USD 1,519.99, so you can start small
• 12-month warranty on major parts, including the laser module itself
• Free shipping over USD 49 in the US and EU, plus 0% APR instalments
• Trustpilot score of 4.9 / 5 across 737 reviews

Cons

• Every refund carries a service fee — 8% unopened, 15% opened but unused, 25% once used — charged on the total order price including tax and shipping
• A returned machine must have “lasered less than 50 times” and keep all original packaging, so a genuine trial is not possible
• Replacements are free only for 15 days; after that it is a 15% fee, and 40% from day 30 to three months, plus return shipping
• Wearing parts — belts, rollers, cables — carry only 3 months, and out-of-warranty repairs bill you for labour, parts, packaging and round-trip freight
• Eight of eleven 3D printers are sold out, including the entire resin line
• Every product page shows a flat 5.0-star rating with no visible review count
• Permanent “sale” pricing — the crossed-out list price appears to be the price nothing is sold at
• No air assist on the tested Nano Pro, and enclosures are an extra

Warranty and Returns: Read This Before You Buy

This is where a Longer3D purchase differs most from a mainstream retailer, and it is the section we would want a friend to read.

Warranty. Major parts carry 12 months on laser engravers and 3D printers, and that does include the laser module. Wearing parts get 3 months. On the UV printer the printhead — the most expensive component — is covered for only 3 months. Packaging and complimentary items carry no warranty. Once you are out of warranty, the policy is explicit that the customer bears labour, spare parts, packaging and round-trip freight.

Returns. The window is 30 days from delivery, and every refund carries a service fee calculated on the total order price including tax and shipping. The tiers are set by the state of the box, not the calendar: 8% if the package is unopened, 15% if it is opened but unused, and 25% once the machine has been used. On top of that, all products, packages and materials must be intact, the machine must have “lasered less than 50 times”, separately purchased materials are not returnable, and exchanging a product after delivery is not allowed at all.

Read plainly: there is no free trial here. Open the box and use the machine and a refund costs you a quarter of what you paid.

Replacements. This is the term most buyers miss. The replacement policy runs three months from receipt, not twelve. Within the first 15 days LONGER pays shipping both ways. Between 15 and 30 days you pay a 15% service fee plus return shipping. And between 30 days and three months you pay a 40% service fee plus return shipping — for a machine that failed, inside a product still under a 12-month warranty. Past three months, replacement is off the table entirely and you are into repair, where out-of-warranty costs fall on you.

So the practical Longer3D timeline is: two weeks to change your mind cheaply, two weeks more to swap a faulty unit for 15%, and after the first month a fault becomes an expensive problem rather than a simple exchange. Test the machine properly in the first fortnight.

What the 4.9 Rating Does and Does Not Tell You

Longer3D holds a TrustScore of 4.9 out of 5 across 737 Trustpilot reviews. That is a large sample and a good score, and most of it reflects real satisfaction with the machines and with technical support.

Two things are worth noticing anyway. First, the distribution is unusual: roughly 98% five-star and 2% one-star, with almost nothing in the middle. Scores shaped like that usually mean reviews are actively solicited from buyers after a good experience — which is legitimate, and also means the average is not a neutral sample of everyone who bought. Second, among the small number of one-star reviews the recurring themes are stock and warranty rather than print quality: orders taken for items not held, slow escalation, and one customer alleging the company withheld promised parts while pressing for a positive review. We could not independently verify that individual account, and it is one review among hundreds — but warranty escalation, not machine quality, is the risk to plan around.

On Longer3D’s own site, every laser engraver displays 5.0 stars with no review count shown at all. Vendor-hosted ratings with no visible sample size are decoration, not evidence. Use the Trustpilot page.

Pricing and Value

The honest value case for Longer3D sits in the middle of the range. At USD 109.99 the Ray5 mini is close to disposable, and you will outgrow it. At USD 1,519.99 the Nano Duo AI competes with enclosed machines from brands with deeper support networks. The sweet spot is the Ray5 at USD 199.99 and the B1 at USD 469.99, where the hardware quality independent testers describe is doing the most work per dollar.

Budget realistically. A Ray5 at USD 199.99 plus an enclosure, air assist and a rotary attachment lands much closer to USD 400, and that is the number to compare against a rival’s all-in price — not the headline. If you want to check today’s configuration and what is bundled, the current Longer3D store listings are the only reliable source, because the promotional prices move constantly.

Verdict

Longer3D earns a qualified recommendation. The machines are better than the price suggests, the software is open, and the warranty on the laser module itself is fair. If you are buying a first or second diode laser for a hobby, a classroom or a small shop, a Ray5 or a B1 is a sensible purchase and the 4.9 Trustpilot score is not an accident.

Be clear-eyed about three things. There is no free trial: opening and using the machine costs you 25% to send it back, and a replacement after the first month costs 40%. Wearing parts are covered for three months, so the running costs are yours from month four. And if 3D printing rather than lasering is what you came for, the shrunken in-stock list is a signal worth respecting. Weighed together, that is a 3.8 out of 5 — a good buy at the right point in the range, bought with the fine print read.

Check current Longer3D prices and stock on the official store before committing, and confirm the enclosure and air-assist options for the model you want.

Longer3D FAQ

Is Longer3D a legitimate company?

Yes. Longer3D is an established manufacturer with a published US support line, a documented warranty and returns policy, and 737 Trustpilot reviews at 4.9 out of 5. The domain longer3d.com now redirects to longer.net, which is the same company rebranded to LONGER.

What is the Longer3D warranty?

Twelve months on major parts for laser engravers and 3D printers, including the laser module. Wearing parts such as belts, rollers and cables are covered for three months. The UV printer’s printhead is covered for three months. Packaging and free gifts are not covered.

Can I return a Longer3D machine if I do not like it?

Within 30 days, but never for free. The service fee is 8% if the box is unopened, 15% if opened but unused and 25% if the machine has been used, charged on the total order price including tax and shipping. All original packaging must be intact and the machine must have “lasered less than 50 times”. Separately, replacements for faulty machines are free only within 15 days, then 15%, then 40% from day 30 to three months.

Which Longer3D laser engraver should a beginner buy?

The Ray5 at USD 199.99 is the best balance of price and capability, with 5W, 10W and 20W options. Choose the B1 at USD 469.99 if you need a larger bed or more power for small-business work. Add an enclosure from the start if the machine will live in a shared space.

Does Longer3D still make 3D printers?

It still sells three FDM models — the LK10, LK10 Plus and LK5 Pro — but eight of the eleven printers listed are sold out, including both resin machines. New product launches are concentrated on laser engravers and UV printers.
