Xact XM300G vs Meltio M600
Start with the differences that could affect your part. Confirm the complete configuration with each supplier.
The big difference
- Xact XM300G uses Powder bed fusion · laser powder bed fusion (LPBF); Meltio M600 uses Directed energy deposition · laser-wire DED.
- These specifications alone cannot tell us which machine will make a given part faster or cheaper.
What this pairing comes down to
This pairing crosses process families — Powder bed fusion · laser powder bed fusion (LPBF) against Directed energy deposition · laser-wire DED — so the decisive factor is usually which process fits the part geometry, material and finishing route, not which machine is bigger. Feedstock differs as well: Metal powder versus Metal wire — powder and wire systems rarely share qualification work. The spec sheet narrows the field; your volumes and quotes decide the buy case — the calculator computes the crossing for this pair.

| Quick description | LPBF machine; compare published build space and laser configuration below. | Wire-fed DED machine; compare energy source, feedstock and published envelope below. |
| Process | Powder bed fusion · laser powder bed fusion (LPBF) | Directed energy deposition · laser-wire DED |
| Build size | 300 x 300 x 350 mm (300 x 300 x 450 extended-feed option) | envelope 300 x 400 x 600 mm |

| Public price | Current quote required | FEDERAL PACKAGE AWARD · 2025 $335,895.41 (dated public record, not a current quote) |
Build size is the maximum published physical space. Energy or laser counts describe the machine configuration; they do not prove a throughput winner.
What do these differences actually mean?
A difference may matter when your part size, material, production plan or process qualification requires it. Confirm the exact application with both suppliers; this page does not declare a winner.
What public specs cannot tell you
Real throughputYour geometry, orientation, parameters and finishing route matter.
Actual yieldPublished specs do not tell you your accepted-part rejection rate.
Total installed priceInstallation, training, service, software and options require a current quote.
Finished-part costPrinting is only one part of the complete accepted-part route.
Service qualityLocal response, parts availability and support experience need supplier validation.
Qualified application fitPublic specs cannot approve your material, parameters, tolerances or inspection plan.
